Editing Jerry Saltzer (section)

==Career==
Jerry Saltzer received an ScD in [[Electrical Engineering]] from [[Massachusetts Institute of Technology|MIT]] in 1966.  His dissertation '<nowiki/>''Traffic Control in a Multiplexed System''' was advised by Fernando Corbató.<ref>{{Cite web|url=https://www.genealogy.math.ndsu.nodak.edu/id.php?id=104301|title=Jerome Saltzer|website=Mathematics Genealogy Project|publisher=Department of Mathematics, North Dakota State University|access-date=28 November 2019}}</ref> In 1966, he joined the faculty of the Department of Electrical Engineering and Computer Science at MIT.

One of Saltzer's earliest involvements with computers was with MIT's [[Compatible Time-Sharing System]] in the early 1960s. In the later 1960s and early 1970s, he was one of the team leaders of the [[Multics]] operating system project. Multics, though not particularly commercially successful in itself, has had a major impact on all subsequent operating systems; in particular, it was an inspiration for [[Ken Thompson (computer programmer)|Ken Thompson]] to develop [[Unix]]. Saltzer's contributions to Multics included the now-standard kernel stack switching method of process switching, as well as oft-cited work on the security architecture for shared information systems.<ref>Jerome H. Saltzer, [[Michael D. Schroeder]], ''[http://cap-lore.com/CapTheory/ProtInf/ The Protection of Information in Computer Systems]'' (Proceedings of the [[IEEE]], September 1975).</ref>

Saltzer led the Computer Systems Research group of MIT's [[Laboratory for Computer Science]]. In the late 1970s and early 1980s, the Computer Systems Research group was one of the key players in the development of the [[Internet]] and [[ring network]] technology for [[local area network]]s.  During this time, Saltzer patented the Proteon ProNet [[ring network]]. He is the co-author of ''[[The Protection of Information in Computer Systems]].''

From 1984 to 1988 Saltzer served as Technical Director of MIT's [[Project Athena]]. "Saltzer@mit.edu" is one of the few Athena usernames with a capital letter, and legend has it that several special case hacks were required to support this functionality. In September 1995 Saltzer retired from his full-time faculty position, but continued writing and teaching part-time at MIT.<ref name="JHS-CV-MIT"/>
