Daniel Slotnick

Daniel Leonid Slotnick (1931 to 1985) was an American mathematician and computer architect who was a pioneer of parallel computing. With John Cocke he published papers in 1958 that first discussed the use of parallelism in numerical calculations, and he served as chief architect of the ILLIAC IV, a massively parallel supercomputer built by the Burroughs Corporation. As principal investigator on a DARPA contract in the early 1970s his work supported ARPANET development, including the Purdy polynomial for password security. He was a professor of computer science at the University of Illinois at Urbana-Champaign, where he led the Center for Advanced Computation, and was elected an IEEE Fellow in 1976.
