IEEE Fellow Peter G. Neumann, a principal scientist at SRI International for five decades and a foundational voice in computer security, system dependability, and risk analysis, died at the age of 93, IEEE Spectrum reported.

Neumann spent nearly 70 years shaping the computing field through pioneering work on risks, system dependability, security, and fault tolerance. He joined SRI International in Menlo Park, Calif., in the 1970s and continued working there until his death.

He possessed a rare ability to identify systemic vulnerabilities long before they became widely recognized. He cautioned that interconnected systems, if poorly designed or insufficiently scrutinized, could fail and become targets for exploitation. He insisted that innovation must always be accompanied by rigorous scrutiny.

Neumann's work spanned computer security, voting-system integrity, nuclear-reactor safety, and software reliability. He founded and moderated the RISKS Forum, a long-running digest on risks to the public in computers and related systems, and authored the seminal text "Computer-Related Risks." His colleagues described him as a rare voice who combined technical depth with unwavering ethical clarity.
