Fredkin's primary contributions included work on reversible computing and cellular automata. While Konrad Zuse's book, Calculating Space (1969), mentioned the importance of reversible computation, the Fredkin gate represented the essential breakthrough. In more recent work, he used the term digital philosophy (DP).
During his career, Fredkin was a professor of computer science at the Massachusetts Institute of Technology, a Fairchild Distinguished Scholar at Caltech, a distinguished career professor at Carnegie Mellon University, and a Research Professor of Physics at Boston University.
