Peter Gabriel Neumann (September 21, 1932 – May 17, 2026) was an American computer science researcher who studied how computer systems fail and advocated for the principles that make them fail less often.. Neumann worked on the Multics operating system in the 1960s, and edited the RISKS Digest columns for ACM Software Engineering Notes and Communications of the ACM. He founded ACM SIGSOFT and was a Fellow of the ACM, IEEE, and AAAS.

Early life and education

Neumann was born on September 21, 1932, in Manhattan, New York,

His mother was commissioned to create a mosaic of Einstein and became friendly with him.

He held three degrees from Harvard University — an A.B. (1954) in Mathematics, and an S.M. (1955) and Ph.D. (1961) in Applied Mathematics and Science. He held a Fulbright scholarship in Germany from 1958–1960.

Career

Neumann worked at Bell Labs from 1960 to 1970. He worked at SRI International in Menlo Park, California since 1971.

Before the RISKS mailing list, Neumann was known for the Provably Secure Operating System (PSOS).

Neumann worked with Dorothy E. Denning in the 1980s to develop a computer intrusion detection system known as IDES that was a model for later computer security software.

Death

On May 17, 2026, Neumann died at Santa Clara Hospital due to complications arising from a recent fall. He was 93.

Memberships and awards

Neumann long served as moderator of RISKS Digest and was a member of the ACCURATE project.

He was the founding editor of ACM Software Engineering Notes (SEN), and was a Fellow of the ACM.

In 2018, Neumann received the EPIC Lifetime Achievement Award from Electronic Privacy Information Center.
