WHAT DOES A NOBEL PRIZE FOR RADIO ASTRONOMY HAVE TO DO WITH YOUR TELEPHONE?
|
|
|
|
It's been a decade since the breakup of AT&T. Has the spirit passed
|
|
out of its Bell Labs, as some charge? Or is it still the preeminent
|
|
technology lab in the US, only "more nimble, more intelligent"?

|
Edward Eckert walks through a storage area behind a yellow
|
|
corrugated-metal warehouse set off a wooded road in piney Warren, New
|
|
Jersey. He presses ahead, into a cold storage area filled by a
|
|
room-sized mobile file cabinet, set on tracks. This is the archive of
|
|
Bell Laboratories, the near-mythological research arm of American
|
|
Telephone & Telegraph. Spinning a lever that opens the space between
|
|
two of the 7-foot-high files, Eckert pulls out an inexpensive black
|
|
Naugahyde case, the kind you can buy at Woolworth's for 15 bucks. He
|
|
unzips the case and fishes out an ancient, fraying 3-inch-by-5-inch
|
|
notebook in purple alligator-patterned leather. Opening it, he
|
|
delicately pages through.
|
|
|
|
The notebook's yellow-gray pages are lined with faded green ink and
|
|
begin with a penciled date, February 1876. Only the first 20 pages of
|
|
the notebook are used, filled with the minutiae of a young Boston
|
|
laboratory assistant named Thomas Watson, who made his recordings
|
|
during the winter of the American Centennial. There are a few simple
|
|
sketches of electrical devices - switches and the like. There is a
|
|
list of expenses that the frugal 22-year-old incurred during that
|
|
winter: "tooth powder - 35," "ice - 10," and even an entry for
|
|
"drawers - 1."
|
|
|
|
Cradling the notebook, Eckert turns to the fourth page. At the top is
|
|
the date - March 10, 1876. Below, in tiny script, are seven words that
|
|
are among the most momentous in the annals of science: "Mr. Watson
|
|
come here I want you."
|
|
|
|
Such were the words of Watson's employer, a 29-year-old Scottish-born
|
|
inventor named Alexander Graham Bell. They were spoken from one room
|
|
to another in Bell's laboratory at 5 Exeter Place. The tale is a
|
|
staple of scientific lore: Bell really did need Watson, having just
|
|
spilled acid on himself. More importantly, his call for help was the
|
|
very first electrically transmitted message spoken over Bell's
|
|
instrument, soon and forever after known as the telephone.
|
|
|
|
Other entries on the fourth page of Watson's notebook record more of
|
|
that day's prosaic, yet epochal communication. "How do you do," Watson
|
|
chronicles. "God save the Queen and several other articulated
|
|
sentences," is the final, triumphant entry on the page of the aged
|
|
notebook, only one of many rarely viewed prizes tucked away in this
|
|
nondescript warehouse in a clearing carved out of the New Jersey
|
|
woods.
|
|
|
|
The artifacts collected here catalog the output of Mr. Watson and his
|
|
descendants, the thousands of scientists who, throughout most of this
|
|
century, gave Bell Labs nearly as much of a monopoly on scientific
|
|
innovation as its parent, AT&T, had on international communications.
|
|
|
|
The caged and locked holds in the Warren warehouse smack palpably of
|
|
the Raiders of the Lost Ark, containing as they do prototypes that do
|
|
nothing less than define the course of our technological century.
|
|
There, in boxes, is the world's first carbon dioxide laser; on a dusty
|
|
table sits the original quartz clock; on a shelf rests the telephone
|
|
on which the first transatlantic call was made; scattered about are a
|
|
pilot's helmet used for the first ground-to-air radio transmission, an
|
|
early loudspeaker used at President Warren G. Harding's inauguration,
|
|
the world's first solar battery, and the original artificial larynx.
|
|
|
|
The archive is the resting place for quaint technological failures as
|
|
well - items like the sadly aged 1954 prototype Picture Phone. Then
|
|
there are the objects whose ubiquity underscores their importance: the
|
|
coffin telephone booth, the black 500 Series Western Electric
|
|
telephone (it once graced every office and home in America), and the
|
|
green, orange, blue, and white versions of the mod, quintessentially
|
|
'60s Princess phone.
|
|
|
|
But here in Mother Bell's basement, the most awesome artifacts of all
|
|
are the more than 100,000 scientific notebooks - tucked away in row
|
|
after two-story, pre-fab, metal-frame row - that hold the notations of
|
|
Bell Labs scientists, modern-day Leonardos whose theories,
|
|
discoveries, and inventions have immeasurably altered humanity.
|
|
|
|
Since its formal incorporation in 1925, Bell Labs's scientific
|
|
fraternity represents a Who's Who of international research. It
|
|
includes seven Nobel Prize winners: William Shockley, Walter Brattain,
|
|
and John Bardeen, inventors of the transistor; Clinton Davisson, who
|
|
demonstrated the wave nature of matter; Arno Penzias and Robert
|
|
Wilson, whose work in radio astronomy confirmed the big-bang theory;
|
|
and Philip Anderson, for his work on the deep atomic structures of
|
|
metals.
|
|
|
|
Notes of the basic research of these Nobel laureates and other
|
|
scientific giants make the Bell Labs archive a veritable pantheon of
|
|
technological achievement. There is the work of Claude Shannon, whose
|
|
seminal information theory provided the framework for computer
|
|
programming; the research of William Pfann, whose "zone refining"
|
|
process made possible the mass production of semiconductors; the
|
|
formulations of Alfred Cho, whose molecular beam epitaxy allowed
|
|
microprocessors to shrink to undreamed-of size and complexity. There
|
|
are the scribblings of Ken Thompson, who, along with Dennis Ritchie,
|
|
developed Unix, the first cross-platform computer operating system;
|
|
and the notebooks of Bjarne Stroustrup, father of the key programming
|
|
language C++.
|
|
|
|
The archive, in total, houses the intellectual foundations of more
|
|
than 25,000 patents, nearly one for each day of Bell Labs's existence.
|
|
It is an outpouring of scientific innovation that -- in its
|
|
breathtaking variety and willingness to push beyond the temporal world
|
|
of telephony - has more than lived up to Alexander Graham Bell's
|
|
refreshing exhortation: "Leave the beaten path and dive into the
|
|
woods."
|
|
|
|
Bell's dictum is carved into the pedestal of his bust in the lobby of
|
|
the sprawling Murray Hill, New Jersey, compound, one of a cluster of
|
|
campuses where many of Bell Labs's 25,000 employees work - all within
|
|
an hour of the institution's original New York home. But if Bell's
|
|
words are cast in stone, much has changed since the time when the
|
|
steely monopoly that controlled - nay, owned - virtually every phone,
|
|
line, pole, switching station, and PBX in America, showered its
|
|
largesse upon Bell Labs, making it, according to one executive, "the
|
|
world's best university." If Bell Labs's university lacks students, it
|
|
comes complete with in-house physics, art, radio-astronomy,
|
|
astrophysics, and its own economics department.
|
|
|
|
The golden age of pure research at Bell Labs began in the mid-'30s,
|
|
when the search for a solid-state device to replace the vacuum tube
|
|
began. It was a spirited period when, one former scientist recalls,
|
|
"people rode unicycles in the halls and invented mind-reading
|
|
machines." It lasted into the late '50s, when Sputnik-phobia drafted
|
|
Bell Labs into the Cold War, even as it remained a bastion of reason
|
|
and safety against the loyalty oaths that were requisite in many
|
|
American institutions for years during the frenzy of McCarthyism.
|
|
|
|
Though staff sizes and budgets remained generous afterward, subtle
|
|
changes in mission and status came along with the anti-establishment,
|
|
anti-scientific Luddism of the late '60s. Regulatory hearings into
|
|
Bell system rate-making in the '70s further diminished its hegemony.
|
|
Then came the 1982 federal court consent decree that broke up the Bell
|
|
system, awarding Bell Labs to AT&T, while setting up a parallel
|
|
organization, Bellcore, as the research wing of the so-called "Baby
|
|
Bells." The transformation accelerated during subsequent internal
|
|
reformations at AT&T, as the company slowly moved away from its
|
|
research orientation and sought to evolve from ponderous scientific
|
|
sovereign into successful business and technology competitor.
|
|
|
|
In his searching 1984 book on Bell Labs, Three Degrees Above Zero,
|
|
Jeremy Bernstein posed a troubling scenario about the effect AT&T's
|
|
breakup would have on the scientific crown jewel that was Bell Labs.
|
|
"Clearly with the divestiture," Bernstein wrote, "Bell Laboratories is
|
|
at a watershed. If all goes well it can continue its great tradition
|
|
of basic and applied research, and if things do not go well it runs
|
|
the risk of becoming just another large, conventional industrial
|
|
laboratory."
|
|
|
|
Has the past decade written the d?nouement in the drama of Bell
|
|
Laboratories's event-horizon research? Other phone companies, like MCI
|
|
and Sprint, have become profitable and competitive - while providing
|
|
little or none of their own basic research - and have cut into the
|
|
AT&T profit margins that fund Bell Labs. Bell Labs nevertheless
|
|
remains a scientific hothouse, with a US$3 billion total budget - $2.7
|
|
billion for development and $300 million for research. It is the
|
|
richest and largest private research lab in the world, still leading
|
|
in fields as diverse as photonics, fiber optics, HDTV, artificial
|
|
intelligence, cellular telephony, digital radio, and computer
|
|
software.
|
|
|
|
Still, Bernstein's decade-old rumination resonates with some veteran
|
|
Bell Labs scientists and executives, who are steeped in the Labs's
|
|
research tradition and watch each change with some trepidation. Are
|
|
things going grandly? In the words of current vice president for
|
|
research and Nobel laureate Arno Penzias, is "the company more nimble,
|
|
the academy more intelligent"?
|
|
|
|
Or has Bell Labs conceded its preeminence in basic science, opting
|
|
instead for the kinds of business-driven technological innovations
|
|
that can come to term in months instead of years or decades; has the
|
|
institution opted, in other words, against the lightness of the
|
|
scientific and toward the gravitational pull of the commercial?
|
|
|
|
Bob Lucky, Arno Penzias's counterpart at Bellcore, believes the
|
|
latter. Lucky, who served at Bell Labs for 31 years, is one of a
|
|
number of "old-timers" who longs for "the golden years," believing
|
|
that "the spirit has gone out of the place, a spirit whose passing
|
|
people mourn."
|
|
|
|
Lucky is quick to point out that many of the changes at Bell Labs were
|
|
necessitated by AT&T's own deregulated, diminished status. And he
|
|
lauds the current AT&T chair, Bob Allen, for fighting hard for the
|
|
Labs US funding and staffing. But with a new president, Daniel
|
|
Stanzione, just beginning his administration, Lucky and others wonder
|
|
if Bell Labs is not necessarily in for a downsizing or a restructuring
|
|
that will see an increasing number of scientists attached directly to
|
|
business units rather than remaining in independent research groups.
|
|
|
|
For his part, Stanzione tries to answer Bernstein's question by
|
|
talking reassuringly about maintaining Bell Labs's historic commitment
|
|
to scientific independence. "We have continued the tradition of both
|
|
basic and applied research," he contends, "with the percentage of our
|
|
budget still going to meet the letter of what (Bernstein) suggests."
|
|
|
|
Bell Labs's eighth president, Stanzione was most recently president of
|
|
AT&T Network Systems's Global Public Networks. Despite 17 years as a
|
|
computer scientist at Bell Labs, Stanzione's concern for the spirit of
|
|
scientific independence jibes most with the newer, business-?ber-alles
|
|
model of the place: "The measure of our success," he says, "will come
|
|
as we move forward and see whether the technology that comes out of
|
|
basic research will prove advantageous to AT&T." His point: "To simply
|
|
provide technology in broad ways and infuse the industry - that's not
|
|
the way our industry works today."
|
|
|
|
Stanzione's pledge to maintain integrity notwithstanding, Bob Lucky
|
|
cannot help but fondly recall the old Bell Labs way as exemplified by
|
|
Bill Baker, the legendary president of the institution in the early
|
|
'70s. Party to a nuisance suit, Baker was being grilled about his
|
|
responsibilities during a deposition. As president, he was asked, wasn't
|
|
it his job to manage people? Baker replied with what he, at least, felt
|
|
should be obvious. "People know what to do," he told his inquisitor,
|
|
referring to Alexander Graham Bell's prescription to seek out the kind
|
|
of men and women who, more than anything else, were unafraid to "leave
|
|
the beaten path and dive into the woods."
|
|
|
|
Where to go for ideas
|
|
|
|
|
|
|
|
"I find it hard to believe that people who are idea-driven are not
|
|
entrepreneurs today," Waring Partridge, AT&T's WASPily articulate vice
|
|
president for multimedia strategy, suggests over mid-morning coffee.
|
|
We are sitting in an empty cafeteria within the central atrium of the
|
|
sprawling, brown-brick cluster that is Bell Laboratories's Murray Hill
|
|
campus. Partridge, whose group brings to market AT&T consumer
|
|
multimedia services, has come over from his Basking Ridge offices to
|
|
tap some of the rich Bell Labs brainpower, as well as to talk with me
|
|
about what he sees as the "new tradition" of AT&T business/science
|
|
dual citizenship - a trend that has seen many once-independent Bell
|
|
Labs researchers go to work directly for AT&T business units.
|
|
|
|
Partridge is a new phenomenon at AT&T. He is an entrepreneur, a former
|
|
McKinsey management consultant and the founder of small
|
|
telecommunications, paging, and cable companies. "Instead of picking
|
|
up my chips and playing golf," he says, he decided, at the age of 49,
|
|
to sign on to one of the world's least entrepreneurial
|
|
mega-corporations. "In the '80s, I said I'd never work for AT&T,"
|
|
Partridge recalls about a company that, to his mind, is still
|
|
"commercially underdeveloped."
|
|
|
|
But when Partridge, who looks and sounds a bit like a techno-George
|
|
Plimpton, finally did take a look at the new, deregulated AT&T, he
|
|
liked what he saw: for starters, a company spending $3 billion a year
|
|
on software alone, with the resources and staying power to force what
|
|
he believes will be the technology passage to the future: the
|
|
convergence of telecommunications, broadcasting, and computing. Like
|
|
many of his AT&T colleagues, when Partridge looks at such soon-upon-us
|
|
wonders as interactive TV, he doesn't see television, he sees
|
|
telephone.
|
|
|
|
During his four years with AT&T, Partridge has become a Bell Labs
|
|
partisan. It is, he says, the kind of place "I go for ideas." But
|
|
Partridge is critical of Bell Labs's history of noncompetition, when
|
|
"people worked so far in the future they could spend their entire
|
|
lives and see their technology in the market only after they retired."
|
|
His conception of the new Bell Labs mirrors that of many of AT&T's and
|
|
Bell Labs's managers.
|
|
|
|
"It's a question of what is needed, more than what is possible,"
|
|
Partridge insists. He is unapologetic about strengthening the
|
|
arrangement under which, as he suggests, research staff "reports to the
|
|
business units that give them money." And that is why, finally,
|
|
Partridge cannot help but latch onto the notion of Bell Labs as an
|
|
entrepreneurial center, a place where, more and more, scientists and
|
|
researchers are allied and aligned with the business units.
|
|
|
|
He expresses his hopes for this notion by citing examples of Bell Labs
|
|
scientists who have taken initiative, saying to their marketing
|
|
counterparts, "We have the technology, what are you going to do about
|
|
it?" And he praises Labs Vice President of Research Arno Penzias for his
|
|
support, telling the story about Penzias's beyond-the-call-of-duty
|
|
endorsement of AT&T's new PC-based telephone videoconferencing system,
|
|
Vistium.
|
|
|
|
Prior to the announcement, in the summer of 1994, it was Penzias who
|
|
brought a couple of Vistium terminals over to AT&T's Basking Ridge
|
|
complex and set them up. Then Penzias, the man who won a Nobel for
|
|
finding proof of the big-bang theory, proceeded to walk up and down
|
|
the halls, banging on executives' doors, bringing them into the
|
|
conference room to give Vistium a try.
|
|
|
|
Throughout the conversation, Partridge returns to one point: the
|
|
successful technology company of the future will likely emerge, not
|
|
from the computer industry, with its vested interest in the
|
|
microprocessor box, but from the telecommunications industry, with its
|
|
tradition of networking and interoperability. He also believes that
|
|
AT&T's long-standing "plug and play" credo, which eschews instruction
|
|
booklets, will be the successful future technological research and
|
|
development paradigm. "Most things that succeed," he suggests drolly,
|
|
"don't require retraining 250 million people."
|
|
|
|
The great intelligence of the network
|
|
|
|
|
|
|
|
Waring Partridge's point is also Eric Sumner's. Sumner is
|
|
demonstrating the Sage Project - recently rechristened the more
|
|
commercial "AT&T TV Information Center" - in a comfortable, gray- and
|
|
cranberry-accented loung area up the hill from the main Murray Hill
|
|
complex, inside the sparkling new Consumer Lab. "It's the AT&T way: no
|
|
manual," says the product development vice president for intelligent
|
|
systems, as he points a handheld control at a virtual remote flickering
|
|
on the screen of a huge Sony television.
|
|
|
|
The TV Information Center is a new AT&T service introduced in January
|
|
1995. It is designed to provide onscreen messaging; rudimentary weather;
|
|
stock, news, or traffic information; but not, Sumner hastens to add,
|
|
visual phone service. Sumner and his colleagues are charged with
|
|
developing and marketing the Information Center and the next generation
|
|
of telephones, a seminal AT&T ritual that comes around only once every
|
|
30 years or so. He traces the evolution of the phone, beginning at the
|
|
end of the last century with the crank devices, evolving to rotary
|
|
telephones in the '30s, touch tones in the '60s, and, Sumner hopes, to
|
|
other Information Center-like screen-display products for the '90s and
|
|
beyond.
|
|
|
|
Unlike earlier eras, though, this time AT&T is no longer a monopoly,
|
|
says Sumner: it "can't dictate." And, heeding the early '60s disaster
|
|
of the Picture Phone (which Sumner suggests never took off because
|
|
"video phones required new behavior"), Consumer Lab researchers are
|
|
careful to use technology already familiar to the average American
|
|
consumer - like the ATM, the television, and the remote control.
|
|
|
|
Indeed, little would fluster the average PC user in Sumner's demo.
|
|
With the push of a button, the TV Information Center can record,
|
|
store, and then visually render telephone messages or faxes; it can be
|
|
programmed to automatically dial up and store voice and text services;
|
|
it can give an instant readout on all the day's relevant stats -
|
|
before you've even brewed your morning coffee, something it cannot do.
|
|
|
|
The Information Center's simplicity - you plug a black box into a
|
|
phone jack and then into your television - is hardly accidental.
|
|
Technological "ease of use," to borrow the jargon, is a major, perhaps
|
|
the major, new Bell Labs paradigm. Retiring Labs president John Mayo
|
|
compares its importance to "improving the efficiency of the vacuum
|
|
tube in the '40s."
|
|
|
|
Sumner once worked under Mayo at the Labs, but transferred to the AT&T
|
|
consumer side when, he says, "a cool new head of consumer products
|
|
brought me over here." But he didn't exactly leave Bell Labs behind:
|
|
he forages there frequently, "looking for what needs to be built, and
|
|
then wandering the halls looking for someone to build it."
|
|
|
|
Sumner has found a collaborator in Thaddeus Kowalski, chief architect
|
|
for products, into whose PC- and circuit-board-strewn lab we wander
|
|
after the TV Information Center demonstration. "This shop allows more
|
|
practical people to have an effect," the stocky, intense Kowalski says
|
|
about products that have come out of his laboratory, as he catalogs
|
|
existing pieces of Bell Labs technology that went into the Information
|
|
Center. "We borrowed the graphics, we lifted the computer codes
|
|
wholesale, and we already have the best transmission and
|
|
file-compression techniques," he says. He winds up echoing the typical
|
|
Bell Labs attitude: "People in the research area had all sorts of
|
|
technology, and they were eager to get it out."
|
|
|
|
Kowalski and Sumner are especially jazzed about another Sage Project
|
|
product that will allow the software in AT&T devices to be automatically
|
|
upgraded over telephone lines by modem. "We can download new codes to
|
|
older machines," Sumner points out. "It's nice for consumers that
|
|
Information Center boxes are less likely to become obsolete."
|
|
|
|
This process is a critical component for what Sumner sees as the
|
|
network-driven "software delivery model of the future." He believes it
|
|
will allow millions of customers to "hook into the intelligence of the
|
|
network."

Plan 9 From Outer Space
|
|
|
|
|
|
|
|
Murray Hill is a maze of industrial structures rivaling the Pentagon in
|
|
sheer potential for misdirection. If you are able to find Corridor C, on
|
|
the fifth floor of Wing 2, you will discover a commons room in which
|
|
computer scientists have long congregated for informal parleys, the
|
|
custom for disseminating information at an institution renowned for
|
|
openness and collaboration. For years, this gathering spot was known as
|
|
the Unix Room: chats held here in the '60s by programmers including Ken
|
|
Thompson and Dennis Ritchie spawned the Unix operating system, the first
|
|
software that allowed different kinds of computers to talk to each
|
|
other.
|
|
|
|
Today, the informal name of the area has changed. It is now know as
|
|
"Plan 9 Land," a tribute to the new operating system that Dennis
|
|
Ritchie's computer techniques research department designed and named
|
|
after Ed Wood Jr.'s legendarily awful science fiction epic, Plan 9 From
|
|
Outer Space.
|
|
|
|
Plan 9, the system, not the movie, is a descendant of Unix. It is a
|
|
shell program that allows different and differently programmed devices
|
|
the freedom to network and process distributively in the simplest and
|
|
most economical way ever.
|
|
|
|
Allowing transparent distributed processing over a network, Plan 9
|
|
already drives such products as the TV Information Center and AT&T's
|
|
World Wide Web 800-number directory. It will, according to Ritchie,
|
|
give users the freedom to work simultaneously with different
|
|
processing activities taking place in varying locations, but, to the
|
|
user, still be part of a unified activity. This is handy, he explains,
|
|
because "sometimes it's better for the data to be near the CPU and
|
|
sometimes it's better - in graphics, for example - to be near the
|
|
user." With Plan 9, the user is unconscious of where the processing is
|
|
taking place -- he or she knows only that a complex job is getting
|
|
done.
|
|
|
|
I ask Dennis Ritchie about the operating system's curious name.
|
|
Sitting in his tiny, cluttered office in Plan 9 Land, around the
|
|
corner from the former Unix Room, he answers by rubbing his chin and
|
|
repeating my question out loud. In his 50s, impish, bearded, and
|
|
dressed down, Ritchie scrunches up his face as he thinks, rattling off
|
|
other whimsical movie names his group has given their creations: titles
|
|
like 8 12, Brazil, Rio.
|
|
|
|
Ritchie shakes his head and launches into what he calls "the very
|
|
complicated history of Unix," a system as famous for its revolutionary
|
|
notion of separating hardware from software as it is for the fact that
|
|
AT&T lost untold millions unsuccessfully trying to license and sell it.
|
|
|

Not that Unix's failure to make money ever dented Ritchie's reputation
|
|
at Bell Labs: in 1983, he won the ACM Turing Award, the same year he
|
|
became a Bell Labs Fellow; since then, he has watched his group become a
|
|
cornerstone for what is today Bell Labs's most prestigious department,
|
|
computing science research. Part of the reason for the department's good
|
|
standing at the institution is that so much of AT&T's business is now
|
|
tied to software development and implementation, even a small tweaking
|
|
of a telephone-switching or billing system can result in mega-savings.
|
|
"Thousands of people are writing code: anything we can do to improve
|
|
their product means we have justified our existence," Ritchie notes with
|
|
a satisfied air.
|
|
|
|
Ten years after sending Unix out to its glorious and unprofitable fate,
|
|
Ritchie admits, he and his group were getting bored. "People wanted to
|
|
do something new, not necessarily with a product orientation," he says.
|
|
"We thought the current versions of Unix and other operating systems
|
|
were too big. It was an engineering issue to design more powerful
|
|
features with a simpler code." The result, underway in 1988, was Plan 9.
|
|
|
|
Ritchie is modest when he compares his hopes for the new operating
|
|
system with the enormous impact of Unix. "The main effect of Unix, the
|
|
portability of an operating system, can be done only once," he says.
|
|
|
|
But Dennis Ritchie's unassuming description - he's trying hard not to
|
|
scare the business types who are still calculating Unix's losses -
|
|
belies the great excitement in Bell Labs about the potential for Plan
|
|
9.
|
|
|
|
Beginning this year, Bell Labs will be offering Plan 9 on CD-ROM, with
|
|
source codes and manuals available to developers at a modest price.
|
|
The idea, Ritchie suggests, is twofold. First, he says, "it is a way
|
|
to get it out and make it visible." And second, "by making it more
|
|
available outside, it will make it more credible inside."
|
|
|
|
Plan 9's importance may be that it is an operating system designed
|
|
from the start to allow computers and communications devices to work
|
|
together in tandem. This, of course, advances AT&T's prime directive:
|
|
complete the interoperability for more and more of the highly
|
|
profitable "fat minutes" that come from the processing and transfer of
|
|
broadband data, naturally, across the AT&T network.
|

|
Firewalls and Bell fellows
|
|
|
|
|
|
|
|
It's noon at the Bell Labs. A score of scientists are gathered intently
|
|
around chess boards set up on a balcony overlooking the lunchroom, which
|
|
is fast filling with a bustling, heterogeneous mix of researchers and
|
|
executives. One game in particular seems to be gaining steam: intent
|
|
players are making aggressive, knowing moves and finishing off by
|
|
slamming their palms down to stop the chess clock. Bill Cheswick, a
|
|
43-year-old programmer in the research computation department, stops for
|
|
a moment on his way into lunch to contemplate the match.
|
|
|
|
Cheswick, co-author of the recently published Firewalls and Internet
|
|
Security: Repelling the Wily Hacker, is an expert on computer-security
|
|
gateways. He is equally well versed in the normally amicable chess game
|
|
between pure research and industrial development that has played out
|
|
between managers and scientists for nearly as long as there has been a
|
|
Bell Labs.
|
|
|
|
Over a minimalist lunch of cottage cheese, bread, and butter, Cheswick
|
|
describes the inside-out world at Bell Labs where the MO is "we tell
|
|
management what we're going to do." Or, as Cheswick restates it,
|
|
"Management presents opportunity; you get to choose your work." This
|
|
attitude is a holdover from the old Bell Labs culture, which Jeremy
|
|
Bernstein identified this way: "Either you do something very useful or
|
|
you do something very beautiful."
|
|
|
|
But perhaps the era of downsizing has had a discernible effect at the
|
|
Labs. "It's possible," Cheswick says, "if you're bright enough, to
|
|
spend the year fishing on a boat, then write a three-page paper, and
|
|
get your salary.
|
|
|
|
"But it's risky," he adds with thoughtful, practiced timing.
|
|
|
|
These days, someone like Bill Cheswick is happy to avoid those risks,
|
|
so delighted is he with his job and the encouragement Bell Labs gave
|
|
him to write his book "on company time." Over a dessert of ice cream
|
|
(a soda fountain's worth of flavors and toppings is kept in a nearby
|
|
freezer), Cheswick spends a moment explaining the seemingly salubrious
|
|
arrangement in which "you keep the royalties, and the company keeps
|
|
the copyright."
|
|
|
|
"It's a good deal," he notes.
|
|
|
|
As are other perks, including his ability to acquire equipment.
|
|
Cheswick, with only a BA, has the authorization to request "any kind
|
|
of computer or software I want with less review than I have with my
|
|
wife when we go shopping." He logs into a new $20,000 3430 Dual CPU
|
|
NCR server to create extremely fast Internet security gateways. "I can
|
|
cut as much rope as I want," he smiles, "and hang myself with it."
|
|
|
|
Aside from the potential for scientific self-strangulation, Cheswick
|
|
does have a few complaints with the current system. "We are part of
|
|
the overhead," he explains. "Therefore, you get bean counters telling
|
|
you, 'I'm paying a percentage of my profits for this, what am I
|
|
getting?'" But in general, the prestige, salary, informality - today
|
|
Cheswick is wearing a T-shirt, jeans, and sandals - and interesting
|
|
assignments at Bell Labs make for an unusually contented and motivated
|
|
work force.
|
|
|
|
This includes those still huddled over chess as Cheswick excuses
|
|
himself and walks out. As he passes, another hard-fought game is
|
|
ending.
|
|
|
|
"Nothing I can do," one of the players shrugs to his audience as he
|
|
concedes the game. "I didn't use my bishops very well."
|

|
|
Pioneer One
|
|
|
|
|
|
|
|
Down one, then another, and yet another long tiled corridor, past
|
|
nitrogen tanks, emergency showers, and innumerable laboratory doors, is
|
|
the Elephant House, so called because of its 30-foot-high ceilings and
|
|
exposed pipes. The place at Murray Hill where Bell Labs technicians
|
|
still get their hands dirty, the Elephant House seems more like a maze
|
|
for white mice, so chaotically and indifferently is its floor space
|
|
divided.
|
|
|
|
Inside one of these chock-full-of-technology warrens is the Light Wave
|
|
Lab, where Frank DiMarcello, technical manager for the optical-fiber
|
|
research department, is finding ways to improve the manufacture of
|
|
optical communications fibers. These filaments of highly reflective,
|
|
light-bearing glass are rapidly replacing copper wire as the neurons of
|
|
the AT&T network, giving it the increased bandwidth that is the key to
|
|
the wired future.
|
|
|
|
DiMarcello works amid the sound of arcing electricity and the odor of
|
|
ozone. The centerpiece of his domain is a 29-foot fiber-pulling tower
|
|
topped with a furnace: rods of incredibly pure silica are heated and
|
|
then drawn down through the tower, untouched by human hands, into a
|
|
continuous 10-kilometer fiber that is 125 microns thick.
|
|
|
|
It is through these fibers that lasers can shoot highly tuned light
|
|
waves carrying an unprecedented and ever-increasing amount of
|
|
information. Information will travel in light pulses, each pulse
|
|
moving as much as 40 billion bits a second. This is the equivalent of
|
|
2.5 million simultaneous telephone conversations over a single strand.
|
|
|
|
DiMarcello fingers a length of optical fiber: it looks like
|
|
monofilament fishing line and can be tied into knots and still
|
|
transmit bursts of photons, carrying a thick bandwidth of information,
|
|
audio, text, or video. Millions of miles of such fiber-optic line will
|
|
be required to fiber the nation. AT&T produces all of its fiber at
|
|
just one specialized facility in Georgia. The race to develop faster
|
|
lasers to pump more data over fiber-optic lines is matched by a
|
|
separate race to speed up the fiber-production process.
|
|
|
|
"We're using larger tubes to try to make 100 kilometers of fiber with
|
|
each," says the thin, intense DiMarcello over the hum, as he picks up
|
|
a 4-inch-thick-by-3-foot-long glass pre-form, looking very much like an
|
|
icicle, that will be melted at the top of the tower.
|
|
|
|
Then he walks me through a door into another room in the Elephant House,
|
|
to a rocket-shaped 70-foot tower. When it is put into operation, it will
|
|
be capable of producing 15 meters of optical fiber a second, far more
|
|
than the 29-foot Pioneer One we just left behind. "We're trying to
|
|
increase the draw-speed," DiMarcello says, gesturing at the huge
|
|
cylindrical tower. "The big tower gives the polymer extra time to cool."
|
|
|
|
Watermarks and "The Wasteland"
|
|
|
|
|
|
|
|
Dave Kristol is demonstrating new Bell Labs technology that creates an
|
|
electronic "watermark," consisting of small shifts in the spacing of
|
|
text that will allow publishers to identify and trace individual copies
|
|
of works that have been printed from computer files. If successful, the
|
|
watermark will be a viable mechanism allowing payment to be extracted
|
|
for printing specific pieces of text off a computer network; it will
|
|
prevent illegal copying and allow for the collection of royalties.
|
|
|
|
"If you hand out copies to 1,000 of your best friends, we can ask you
|
|
to pay," says the Young Turk in the distributed systems research
|
|
department. Then Kristol laughs and describes another feature his group
|
|
is working on. "We call it an anonymous credit card," he says about a
|
|
system in which "a person online can pay, but the seller doesn't know
|
|
to whom his material is going."
|
|
|
|
As he speaks, Kristol continues working his way through a demonstration
|
|
of Bell Labs's SEPTEMBER Project. The nightmare of every online freedom
|
|
fighter, Bell Labs's "Secure Electronic Publishing Trial" project
|
|
offers the possibility of bringing the electronic network into the realm
|
|
of laissez faire economics and making "pay per piece" electronic
|
|
publishing possible.
|
|
|
|
If electronic copywriting and producing online credit cards is his
|
|
official raison d'?tre, Kristol is more than happy to move on to
|
|
demonstrate his real love - audio and video over the World Wide Web,
|
|
into which AT&T has jumped with a vengeance. On his workstation,
|
|
Kristol calls up a short video of AT&T chair Bob Allen giving a
|
|
speech. It is being sent from a server at another Bell Labs campus and
|
|
is part of what is known as "Nemesis," a network-friendly service that
|
|
allows video and audio to be sent and viewed straight off a server as
|
|
needed, rather than forcing a user to download an entire file first.
|
|
|
|
Kristol is equally proud of the Bell Labs's version of Internet talk
|
|
radio and the in-house "jukebox," a server on which various recordings
|
|
are stored. He plays a portion of the radio series Hell's Bells: A
|
|
Radio History of the Telephone, before getting to the p??ce de
|
|
r?sistance - over a speaker hooked up to Kristol's workstation comes a
|
|
ghostly version of T. S. Eliot's signal poem, "The Wasteland." The
|
|
solemn, late autumn sky outside Kristol's office window seems to close
|
|
in on us as Eliot's reedy voice intones, "Here is no water, but only
|
|
rock."
|
|
|
|
While it is not quite "Mr. Watson come here I want you," the analogy is
|
|
clear and powerful.
|
|
|
|
Not as OK as it used to be
|
|
|
|
|
|
|
|
Through the floor-to-ceiling windows in Arno Penzias's office, the
|
|
setting sun glows fiery bronze above the trees topping the New Jersey
|
|
ridges that march off to the West. The office, with its rich blond
|
|
carpet, blond wood desk, and generous shelving, may be the most
|
|
sumptuous room at the institutional, World War II-era Murray Hill site.
|
|
|
|
On top of Penzias's desk sit two computers, one of them with a camera on
|
|
top; this is the Vistium system of which he is so proud. On the wall
|
|
above it is a photo of the horn-reflector antenna that Penzias and
|
|
Robert Wilson trained on outer space to detect the background radiation
|
|
residue from the big bang.
|
|
|
|
Now Bell Labs's vice president for research, Penzias enters his office
|
|
in time to chat with an assistant who is putting files, including
|
|
several games, on an AT&T 486 notebook. Penzias will try them over the
|
|
weekend; he confers with the assistant about one of them, a game called
|
|
Shanghai that is based on mah-jongg.
|
|
|
|
This spirited interest in games is a happy sign. There were times during
|
|
the last decade, when Bell Labs scientists felt they had to hide what
|
|
amounted to technological game-playing from AT&T. There was Belle, the
|
|
Bell Labs's champion chess-playing computer, retired in the early '80s.
|
|
There was a ping-pong playing robot, a marvel of trajectory plotting,
|
|
fuzzy logic, and space/time coordination that was quietly ditched
|
|
because scientists feared stockholders and rate payers might grow cranky
|
|
with such seeming frivolity.
|
|
|
|
Bellcore's Bob Lucky, who moved into Arno Penzias's spot when the
|
|
latter was promoted to vice president of research, recollected an even
|
|
closer-to-home example of AT&T's unease with nonproductive science.
|
|
When Lucky inherited Penzias's office, he found a plaque made from an
|
|
AT&T advertisement produced when Penzias and Wilson were awarded their
|
|
Nobel in 1978. "What does a Nobel Prize have to do with your
|
|
telephone?" the ad asked. The questions troubled Lucky. "It didn't
|
|
ring true," he commented. "Why should you have to explain why the
|
|
discovery was important, why it was good for the telephone?"
|
|
|
|
It was an important question, and a difficult one for Penzias, who,
|
|
although clearly sympathetic to the need for intellectual elbow room,
|
|
seems compelled to toe the AT&T market-driven-technology party line.
|
|
In a discussion about Bell Labs's grand dilemma, Penzias is almost
|
|
wistful as he reflects on the Unix Room and the highly consequential
|
|
results of just hanging out. "One doesn't know when it's best to
|
|
work," Penzias says, his precise English touched by an accent
|
|
somewhere between Berlin and Brooklyn. (He was a youthful refugee from
|
|
Hitler's Germany.) "It's hard to assign a time."
|
|
|
|
I ask if it is still OK at Bell Labs to set your own time. "Reasonably
|
|
so," he answers. "But not as OK as it used to be."
|
|
|
|
Not entirely satisfied with his response, Penzias tries out an analogy.
|
|
"We've started operating more as ranchers than hunters and trappers," he
|
|
says. "We used to run a trading post, where you'd come in and swap a
|
|
good story for a grubstake." He goes on, "You'd get nitroglycerin, a
|
|
long rope to lead your donkey, and you'd come back with nuggets or a
|
|
good excuse."
|
|
|
|
Penzias, who has been at Bell Labs for 34 years, was an outspoken foe of
|
|
the breakup of the Bell system. There is a residue of scorn in his voice
|
|
when he talks about living "in a country where government declares
|
|
victory when you buy from overseas." He maintains a certain longing for
|
|
the era when it was not considered good form to let researchers "find
|
|
out too much about development because they might get spoiled."
|
|
|
|
"Today," Penzias continues, "we have an environment of interaction;
|
|
while it is still collegial, you live with the business people." He
|
|
admits that at today's Bell Labs, "we want more process and
|
|
responsibility," but allows that "we have to be more careful - not all
|
|
searches are equal."
|
|
|
|
Not that this is a situation without advantages. Clearly, Bell Labs is
|
|
still a scientific powerhouse. "One of our great luxuries," he admits,
|
|
"is that we don't always have to be right."
|
|
|
|
Another great advantage is that Bell Labs can invest in defensive
|
|
research. "We don't want to be blindsided," he says, citing the
|
|
example of a project investigating the neural nets of small animals to
|
|
see if they are applicable to future chip design that more nearly
|
|
approximates living intelligence. "Biology has a lot to teach us," he
|
|
says. He also mentions some of the other marvels still pouring out of
|
|
Bell Labs: the optical amplifiers and wavelength multiplexing
|
|
technology that will broaden bandwidth to unimaginable degrees; the
|
|
revolutionary digital-audio compression algorithms; the optical
|
|
trapping technology that allows levitation and precise manipulation of
|
|
matter down to the molecular level; the new type of semiconductor
|
|
laser, the quantum cascade, able to emit light at fantastically
|
|
specific wavelengths; and even the newly created lead-free brass
|
|
alloy. Then there are the Nobel Prize winners of the future.
|
|
|
|
But, finally, Penzias is a realist when it comes to assessing Bell
|
|
Labs's role. "We're filling in a piece of the technology puzzle, an
|
|
important piece but one not as grand," he says. Still, his belief in the
|
|
importance of Bell Labs is as unassailable as it is unequivocal. "We're
|
|
demonstrating that the investment in knowledge pays off in the long
|
|
run," he says flatly. "America and the world would be a far different
|
|
place without us."
|
|
|
|
Innovation, Not Invention
|
|
|
|
|
|
|
|
An interview with Bell Labs's new president, Daniel Stanzione.
|
|
|
|
Punctuating the ongoing evolution at Bell Laboratories, 23-year AT&T
|
|
veteran Daniel Stanzione is slated to take over as Bell Labs's eighth
|
|
president on March 1, replacing outgoing John Mayo. A computer scientist
|
|
by training, Stanzione's charge is to move the institution increasingly
|
|
toward software development and away from the materials sciences that
|
|
have historically been its strength. Wired asked Stanzione to comment on
|
|
some of the important trends in science and at Bell Labs.
|
|
|
|
Wired: How has the focus changed at Bell Labs over the last decade?
|
|
|
|
Stanzione: It has gradually evolved as the industry has changed. Many of
|
|
our competitors don't spend as much spotting new technology curves that
|
|
will cause industry changes, but AT&T spends US$3 billion a year on R&D.
|
|
|
|
What are those curves?
|
|
|
|
There are three basic network areas: the broadband networks, the
|
|
wireless networks, and client-server computing. If you go back five to
|
|
ten years, you'd see that these three major network thrusts were not
|
|
dominating attention, activity, or money as they are today. All of
|
|
them are getting more funding. And in each, software is a key.
|
|
|
|
Are there fundamentals that underpin all of those areas?
|
|
|
|
They all involve developments in user interface. If you look at the
|
|
history of these networks, you'll see that they were preceded by the
|
|
invention of a user interface. Before there were telephone networks,
|
|
somebody had to invent the telephone; before there were cellular
|
|
networks, someone had to invent two-way radio handsets; before LANs,
|
|
the PC had to come along; and before a new age in which broadband and
|
|
wireless will allow networks to take off, someone will have to come up
|
|
with new user interfaces. There are two other fundamentals: silicon
|
|
and software.
|
|
|
|
The AT&T ad that was done after Penzias and Wilson became Nobel
|
|
laureates in 1978 asked the question "What does a Nobel Prize have to
|
|
do with your telephone?" What is the answer to that question?
|
|
|
|
Most technological advances that profoundly affect people's lives
|
|
have, at their root, changes in the basic sciences. At Bell Labs, we
|
|
have a dual obligation and also a dilemma: to make fundamental
|
|
contributions for the betterment of all, and also to use technology
|
|
for AT&T's competitive advantage in the marketplace.
|
|
|
|
How do you do good and also do well?
|
|
|
|
We need to do a better job getting that technology to market. You have
|
|
to differentiate between invention and innovation. Invention is a
|
|
wonderful quality of uniquely brilliant people but does not
|
|
necessarily turn into real products and services. Innovation is
|
|
getting technology to the marketplace. Never has there been an
|
|
opportunity for technology to have such an impact around the world. If
|
|
innovation is being able to get invention to the marketplace, then the
|
|
golden age is still ahead of us.
|
