IBM-701 Team Member McClelland Born

IBM-701 Team Member William F. McClelland is born in Bronxville, New York. He received a BS from MIT in 1947 and immediately joined IBM Watson Laboratory. At IBM he programmed the SSEC (Selective Sequence Electronic Calculator) for John von Neumann and was chairman of the Mathematics Planning Group in 1951-1953. This group developed computer specifications to solve complex mathematical problems, performed basic research in the use of a stored-binary calculator, and wrote and tested programs that were supplied to the customers of the 701.

McClelland had held various management and marketing positions at IBM until his retirement in 1982.
