From Columbia to CUNY
Kenneth King was Director of the Columbia Computer Center and Ira Fuchs Manager of Systems Programming. These two got to know Eisenpress and had the foresight to encourage his curiosity. He was hired part-time to train the operators and then full-time as a systems programmer in 1971.
In 1973, King was hired by the City University of New York as Dean of Computing, with the specific mandate to create the new central CUNY computer center at 57th Street. He brought with him many of his Columbia staff - Eisenpress, Ben Yalow, Ira Fuchs, ... who made up the initial core of the CUNY/UCC systems group.
