He received his PhD in mathematics ( number theory) in 1969 from the University of California, Berkeley under Derrick Henry Lehmer for a thesis entitled "Proof of a Conjecture of Gauss on Class Number Two". 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 In mathematics, analytic number theory is a branch of number theory that uses methods from mathematical analysis to solve problems about the integers. It is often said to have begun with Peter Gustav Lejeune Dirichlet's 1837 introduction of Diric ...
, he moved to AT&T Bell Labs. At Bell Labs, Weinberger contributed to the design of the AWK programming language (he is the "W" in AWK), and the Fortran compiler f77. A detailed explanation of his contributions to AWK and other Unix tools is found in a

at Princeton University. Another interview sheds some light on his work at Google. Both interviews also confirm rumors about his involvement in early digital photography, especially the abuse of a photograph of his face for demonstrating digital imaging effects. 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 th
