shameless wikipedia ripoff:

Ritchie was best known as the creator of the C programming language and a key developer
of the UNIX operating system, and as co-author of the definitive book on C, The C Programming Language,
commonly referred to as K&R (in reference to the authors Kernighan and Ritchie).

Ritchie’s invention of C and his role in the development of UNIX alongside Ken Thompson has
placed him as an important pioneer of modern computing. The C language is widely used today in
application, operating system, and embedded system development, and its influence is seen in
most modern programming languages. UNIX has also been influential, establishing concepts and
principles that are now precepts of computing.

Ritchie was elected to the National Academy of Engineering in 1988 for “development of the “C”
programming language and for co-development of the UNIX operating system.”

An amusing photo

Here’s a publicity photo from about 1972, showing Ken and me in front of a PDP-11.

From the right, the major items of equipment are

At the far right, on the table, are what someone discerned was a VT01A storage-tube display
(based on Tek 611) and a small keyboard for it. Slightly hard to make out.
A main CPU cabinet, partly behind the table. The processor is a PDP-11/20; it must have been
our second one, with the Digital Special Systems KS-11 memory management unit. Our very first
just said “PDP11,” not “11/20.” The arrays of distorted rectangles above it and in other
cabinets are the labels on DECtape canisters.
Another cabinet. Careful examination of the image by Steve Westin detects the top of the
bezel of an 11/45 CPU barely peeking above the TTY to the right of the one Ken is typing at. A
paper tape reader is above it.
The third cabinet sports a dual DECtape drive at the top.
A cabinet with another DECtape drive, probably also containing BA-11 extension boxes within.
A cabinet with RK03 disk drives. These were made by Diablo (subsumed by Xerox) and OEMed to
Digital. Digital later began manufacturing their own version (RK05).
A cabinet containing RF11/RS11 controller and fixed-head disks. By this time / and swap
space lived there, while /usr was on the RK03s.
On top of the machine are what look like magtapes. A probable TU10 transport is barely
visible just below Ken’s chin, at least if you have the monitor brightness and contrast adjusted
favorably.

In front, we have

Ken (sitting) and me (standing), both with more luxuriant and darker hair than we have now.
Scientific American March 1999 p. 48 should have checked the IDs; we’re interchanged in its
caption of this same picture.
