Vollum Adjunct Professor of Science and

Director, Center for Advanced Computation, Reed College [1978-2012]

Prof. Richard E. Crandall.

Richard Crandall was also an Apple Distinguished Scientist, and had previously been Apple's Chief Cryptographer, the Chief Scientist at NeXT, Inc., and recipient of the Vollum Chair of Science at Reed College. In 1997 he founded a consulting firm, Perfectly Scientific, Inc., dedicated to industrial algorithm design. His primary interest was interdisciplinary scientific computation, though he also authored numerous theoretical papers in quantum physics, biology, mathematics, and chemistry, as well as various patents across engineering fields.
