I first encountered Peter G. Neumann at the PC party for Security in Washington, DC, back around 2000. Peter was playing a grand piano and leading a group in singing songs from Gilbert and Sullivan, Tom Lehrer, and more. I later learned that Peter can play many more instruments.
Peter and I met for lunch in 2007 in Palo Alto, not far from where he works at what used to be Stanford Research Institute and is now SRI International. I was going to speak at Apple and Google over the following week about the failure of current measures that were supposed to be making our systems more secure. Peter encouraged me, then regaled me with stories about the Multics design.
Peter has been involved in security since 1965, starting with his work on the Multics file system and overall Multics development, continuing with a provably secure operating system (PSOS). His current project involves the CHERI (Capability Hardware Enhanced RISC Instructions) hardware-software system co-design [1]).
