PENDERGRASS JAMES T. PENDERGRASS Captain USN (Ret.) Died Tuesday, February 3, 2009 in Hightstown, NJ at age 90. Born in Bala Cynwyd, PA he earned a BA in economics from Cornell University and an MA in mathematics from Columbia University before entering the Navy in 1941. His navy career was primarily in the cryptologic service.

In the summer of 1946 he attended the famous special course on digital computers at the Moore School of Electrical Engineering at the University of Pennsylvania conducted by John Von Neuman. His report from that course and his subsequent leadership were instrumental in establishing the naval cryptologic service‘s pioneering program to develop electronic digital computers. After a distinguished naval career he retired in 1965. He spent the following 15 years working as a mathematician at the Institute for Defense Analysis in Princeton NJ. His avocation was swimming and he was a nationally ranked Masters swimmer.
