PJW's Face

``For some reason, the portrait of Peter Weinberger has always been our most popular target for picture editing experiments. It started a few years ago when Peter was raised to the rank of department head and was careless enough to leave a portrait of himself floating around. On a goofy Saturday evening at the lab, Rob Pike and I started making photocopies and, to emphasize Peter's rise in the managerial hierarchy, prepared a chart of the Bell Labs Cabinet with his picture stuck in every available slot. Peter must have realized that the best he could do was not to react at all, if at least he wanted to avoid seeing his face 10 feet high on a watertower. Nevertheless, Peter's picture appeared and reappeared in the most unlikely places in the lab.

Within a few weeks after AT&T had revealed the new corporate logo, Tom Duff had made a Peter logo that has since become a symbol for our center. Rob Pike had T-shirts made. Ken Thompson ordered coffee mugs with the Peter logo. And, unavoidably, in the night of September 16, 1985, a Peter logo, 10 feet high, materialized on a watertower nearby.''

Two different sets of T-shirts were made, shown above (thanks to Brian Redman, Pat Parseghian, and Jim McKie for unearthing the earlier shirts). Rob's original version was plain white (above left), with just the PJW face. Later Paul Glick had a second edition made in blue. This version of the shirt had the slogan Where the avant-garde meets the rear guard on the back. Another version of the shirt (above right), in both blue and white, showed a digitized rendering of pjw's face.

Brian Redman recovered the original of the Bell Labs Cabinet chart and provided a scan of this important document (see image on the right). For the sentimental at heart, beyond the pictures, we can see a few cherished names on the chart from the old days at Bell Labs, such as John Tukey, Arno Penzias, and Vic Vyssotsky.

There is only one known picture of the watertower with the logo. It is shown to the right. There was not much time to record the event: the image was painted over by plant management within one day after it appeared. Meanwhile, these two watertowers have also disappeared. Many years ago they were replaced with a single, much larger, structure that could in principle also accomodate a much larger version of the logo.

We do not know for certain who painted the picture on the watertower. Mechanically, it was done with a large template and spray paint. We do know that the paint itself was vouchered a few days later as a business expense by Fred Grampp, on behalf of a pseudo-employee G.R. (Grace) Emlin (login: gremlin), who had at that time already been entered successfully into most official databases at Bell Labs, and regularly received mail at her mailbox at 2C-501 (the Unix room).

There were many more uses of Peter's image than can be recorded here. We managed to get a transformation of the image on the cover of the AT&T Technical Journal in March 1987 (left). But we also made sure it appeared in lots of other, less conspicuous places. It appears, for instance, within the layout diagrams of some of the chips that our center produced at that time, and it appeared as a hidden tiny image somewhere on every CD cover image that we produced.

For instance, in the CD cover image on the right, PJW's face is visible in the dark area of the wrist. In the original Plan9 distribution CD, shown below, the PJW face is held by one of the characters from the movie (see arrows).

Insiders also know that hidden images of PJW can be found embedded in the cement under the machinery that was being installed around that time in our buildings. The picture on the left was taken a few days before something big and heavy was installed on the spot with the newly poured cement. Later, this slab of cement was hiding underneath new offices from the Bell Labs PR department. No doubt, the occupants of these offices didn't have a clue about it. Norman Wilson has confessed to making the imprint in the cement, using a stencil cut-out of the PJW logo.

Below is a list, in no particular order, of some the other uses of PJW's face over the years:

• PJW's face was spliced into a disabled logo outside the mens room on Stair 8 (the same stair where a large PJW face still appears on the wall in the form of magnets. The state of the magnet arrangement in March 2009 is shown to the right, in a photo taken by Peter Patel-Schneider, see also below for more on this).
• PJW's face for a brief while replaced the 5th floor indicator on the Stair 9 elevators (the 5th floor is where the original Unix room was and where most of the Unix people had their offices).
• One of the early BLIT terminals (designed by Bart Locanthi and Rob Pike, both from 1127), had a screen saver about which we will say little more than that it consisted of the PJW logo and a kicking donkey (if memory serves, we had scanned in the kicking donkey from one of Edward Muybridge's famous photo sequences).
• A transformation of Peter's image also appeared on the cover of the magazine Computer Graphics in November 1985, Vol. 19, Nr. 4. The scan on the right is courtesy of Renee French.
• PJW's face appears painted on the wall in at least one of the fifth floor offices in the Murray Hill building, 2C-517 (see the back wall in the image on the right). The office used to belong to Ed Sitar, our system administrator at the time, now retired. (Ed also appears in the 9th picture in the book, on pages 50 and 51.)
• An approximately four by four feet rendering of PJW's face, built entirely from small round magnets, appeared on the (metal) walls of stair 8, at the fifth floor. The magnets appeared when Peter Weinberger left Bell Labs to join Renaissance Technologies, in around 1996. (See the picture on the right above from, which was taken in 2003.)
• Many hundreds of prints of PJW's face were distributed as masks (with eyes and mouths cut out) at a large lab-wide meeting in the Murray Hill Auditorium, when Peter's promition to VP was announced. Unbeknownst to Peter, the masks were distributed at the entrance to the auditorium, at the start of the meeting, and on cue, when Peter took the microphone, everyone in the audience donned his or her mask, to great effect.
• A special PJW symbol was added to the symbols font of our troff typesetting system. This led to the creation of a special PJW eyechart, with the PJW face rendered in a variety of sizes. (Picture courtesy of Bob Flandrena.)
• When we decided to try and branch out from 2-d imaging into 3-d surface rendering, Peter agreed to let us take a plaster cast of his faces. Lillian Schwartz (picture 19 in the book, pages 70 and 71) agreed to help make the mask, which happened in Lillian's studio. A polaroid picture I took of the event is on the right. Our initial plan had been to use a 3-d cast of PJW's face to replace the bust of Alexander Graham Bell, in the Murray Hill lobby on April 1st. Luckily, we did not attempt this feat; it probably would not have been appreciated much.
  A little while later, Rob Pike arranged for a (green) rubber copy of the fragile plaster mask to be made by David Hagelbarger, then just recently retired from Bell Labs. Both copies of the mask are still around. (Norman Wilson is the keeper of the original plaster mask, and Gerard Holzmann is the guardian of the green rubber cast.)
• When Norman Wilson left Bell Labs in 1990, to join the University of Toronto, we commemorated his departure with a rendering of PJW's face in solid Belgium chocolate. This was accomplished with the help of the rubber copy of the mask, and a slowly melted large block of chocolate. If memory serves, Peter payed for the chocolate.
• Similarly, when Rob Pike left in October 2002 to join Google, we used PJW's image for a cake. Margaret Smith is putting the finishing touches to the cake in the picture on the right.
• Pjw's face is displayed in the upper-left side corner of Rob Pike's sam text editor, the de facto editor of many Unix users. (It also very handily helps survival on Windows systems.) In more recent incantations of 'sam' the pjw face is also used to render unrecognized character codes.
• More broadly, in the Plan 9 software, for instance when you cat a file, all characters missing from the font (as well as NUL and U+FFFD characters) render as tiny pjw faces.
• Another notable use of Peter's face was in the 'faces' program that announced incoming mail on the 1127 machines (research, fs, coma, grigg, etc.). When no picture for the sender is available, our mail server shows PJW's iconized face instead.
