Edward H. Sussenguth
American engineer (1932-2015)

Edward H. Sussenguth Jr. (October 10, 1932 – November 22, 2015) was an American engineer and former IBM employee, known best for his work on Systems Network Architecture (SNA). He was also a contributor to the architecture of IBM's Advanced Computer System (ACS).
Biography
Born in Holyoke, Massachusetts, Sussenguth received a Bachelor of Arts (A.B.) in 1954 from Harvard University, a Master of Science (M.S.) in electrical engineering in 1959 from Massachusetts Institute of Technology (MIT), and a Doctor of Philosophy (Ph.D.) in 1964 from Harvard.
After he served at the United States Navy as an officer in the Pacific Fleet, Sussenguth joined IBM in 1959. Sussenguth started in 1959 in the Research Division in the development of formal language descriptions.
This work led to Sussenguth meeting Kenneth E. Iverson and Adin Falkoff. Iverson had developed a formal notation, which was documented in a book A Programming Language. It was the original version of the programming language APL. Chapter 2 of A Programming Language had used Iverson's notation to describe the IBM 7090 computer. In early 1963, Falkoff, later joined by Iverson and Sussenguth, proceeded to use the notation to produce a formal description of the IBM System/360 computer then under design.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Edward H. Sussenguth”, the useful work is to connect “american engineer (1932-2015)” to the records capable of establishing context and consequence.
The entry’s evidential value lies in the named roles, institutions and publications that can be tested against primary documentation. The source revision retrieved here is dated May 28, 2025. The linked authority identifier is Q15995511. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1932, 2015, 1954 and 1959.
A concise life account rarely captures disputed attribution, private networks or the changing language used to describe a career. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
