Peter Jay Weinberger (born August 6, 1942) is a computer scientist best known for his early work at Bell Labs.

After holding a position in the Department of Mathematics at the University of Michigan, Ann Arbor, where he continued his work in analytic number theory, he moved to AT&T Bell Labs.

[2] A detailed explanation of his contributions to AWK and other Unix tools is found in an interview transcript at Princeton University.

[3] When Peter Weinberger was promoted to head of Computer Science Research at Bell Labs, his picture was merged with the AT&T "death star" logo of the mid-80s, creating the PJW Face image that has appeared in innumerable locations, including T-shirts, coffee mugs, CDs, and at least one water tower.

The sole remaining PJW Face at Bell Labs is somewhat in disarray, but there are plans afoot to repair it.
