Edward H. Sussenguth

Edward H. (Ed) Sussenguth Jr. (October 10, 1932 November 22, 2015) was an American engineer and former IBM employee, known best for his work on IBM Systems Network Architecture. He was also a contributor to the architecture of IBM's Advanced Computer System (ACS) system.


Born in Holyoke, Massachusetts Sussenguth received his BA in 1954 from Harvard University and his MA in Electrical Engineering in 1959 from Massachusetts Institute of Technology,[1] he received his PhD in 1964 from Harvard.[2]

After he served at the United States Navy as officer in the Pacific Fleet, Sussenguth joined IBM in 1959.[3] Sussenguth started in 1959 in the Research Division in the development of formal language descriptions. In 1965 he joined the Advanced Computing Systems project to work on high performance computers. In 1970 he became Director of Architecture and Planning in the new Communications Systems Division, where he turned his attention to networking and high speed communications. In the last year before his retirement in 1990, he was appointed first President of the IBM Academy of Technology, which he held for a year.[4]

Sussenguth had been advisor to the National Bureau of Standards and Visiting Professor at some universities. He was elected Fellow of the Institute of Electrical and Electronics Engineers (IEEE) and received multiple awards and honors, In 1981 he was awarded the IBM Fellow[5] for "technical leadership in the development of system network architecture.";[2] in 1988 he received the Data Communications Interface Award;[3] in 1989 the IEEE Simon Ramo Medal; and in 1992 he was elected members of the National Academy of Engineering (Computer science).
