Harry Polachek received his undergraduate degree in mathematics from Yeshiva University and a masters degree from Columbia University. For financial reasons, he attended Columbia part time to complete the course work for his PhD. During the war, he took a job at Aberdeen Proving Ground, computing firing tables using the Bush Differential Analyser. He finished his dissertation at Columbia after the war. Polachek recalls being introduced to the work on the ENIAC at the University of Pennsylvania as part of his work at Aberdeen. He also met John von Neumann for the first time. After the war, he began his career with the Navy,  joining the Navy Bureau of Ordnance and moving on the the Naval Ordnance Laboratory and the David Taylor Model Basin. He recounts his interaction with John von Neumann on a range of problems in computing, including explosives,  shock waves, and Mach effects. He relates the story of the design and development of the Naval Ordnance Research Calculator (NORC) (in which John von Neumann had a hand) and the development of the UNIVAC at the David Taylor Model Basin.
