In 1946, he joined the Electronic Computer Project at the Institute for Advanced Study (IAS) in Princeton, New Jersey, under the leadership of John von Neumann. The project built a parallel stored program computer called the IAS machine that was the prototype for a number of machines such as the MANIAC I, ORACLE, and ILLIAC series. Pomerene designed and implemented the adder portion of the arithmetic unit.[2]
Collaborating with engineers such as Bruce Gilchrist and Y.K. Wong, they invented a fast adder which incorporated a speed up technique for asynchronous adders reducing the time for additive carry-overs to propagate. This design was actually later incorporated in one commercial computer, the Philco TRANSAC S-2000, introduced in 1957, the first commercial transistorized computer.[2]
Pomerene became chief engineer on the IAS computer project from 1951 to 1956.[1][2]
In Summer 1956, Pomerene joined the IBM Corporation in Poughkeepsie, where he and several others started the development of various electronic computer systems such as the IBM 7030 and Harvest computers.[3] He was appointed an IBM Fellow in 1976. He held 37 patents when he retired from IBM in 1993.
