Tom Van Vleck


Tom Van Vleck is a computer software engineer and security expert. Enrolling at the Massachusetts Institute of Technology as a freshman in 1961, Van Vleck chose MIT due to his interest in computers. Although MIT lacked a computer science major at the time, Van Vleck as a mathematics major took courses in computers and programming that were spread across several departments. These early courses introduced Van Vleck to machine language and FORTRAN, with the textbook on assembler for the IBM 7094 written by Fernando Corbato, William Poduska, and Jerry Saltzer.(1)

In 1963, Van Vleck took a part-time programming job with MIT's Project MAC, a DARPA-funded effort at the MIT Research Laboratory of Electronics that conducted research in operating systems, artificial intelligence, and the theory of computation.(2) It was at Project MAC that Van Vleck first worked with MIT's CTSS (Compatible Time Sharing System) that ran on the IBM 7094, and was first demonstrated in 1961.(3) In 1964, Van Vleck found part-time programming work in the MIT Political Science Department, where he wrote code for simulation, survey analysis, and statistics for multiple computer systems including CTSS. As part of this experience, Van Vleck spent many hours exploring the CTSS system to determine how it functioned, and contributed his own programs to the CTSS user community.

After graduating in 1965, Van Vleck joined the MIT Computer Center as a full-time member of the research staff, continuing to work for Professor Ithiel de Sola Pool, who oversaw Van Vleck's programming job in the Political Science department. It was during this time that Van Vleck co-developed one of the first e-mail applications, written for CTSS.(4) Van Vleck transitioned to Project MAC that same year, where he helped administer CTSS resources and assist remote CTSS users, such as Bell Lab's Ken Thompson and Dennis Ritchie, who used CTSS for their contributions to the Multics project. Van Vleck himself began work on Multics, contributing papers on resource accounting and system administration, in addition to his responsibilities with CTSS. Following work on system boot and other Multics facilities, Van Vleck moved to the MIT Information Processing Services Center in 1969, where he managed CTSS system programming, and prepared IPS for Multics.(5)

In 1974, Van Vleck left MIT for Honeywell's Cambridge Information System Laboratory (CISL), where, between CISL and Honeywell Phoenix, he continued worked on Multics until 1981. During these years Van Vleck contributed to many components of Multics, including the Multics New Storage System (NSS).(6) Following his time at Honeywell, he worked as a software designer, engineer, and research scientist, which included problems in computer security. Tom Van Vleck currently operates his self-named consulting firm, which offers expertise in web applications, programming, security, and other computer-related fields.(7)

In 2007, Tom Van Vleck contributed significantly to the release of Multics source codes and documentations as free software.(8)

He has taken a leading role in the wide-ranging and invaluable externalMulticians website, which has several notable articles on computer-security issues, including "A brief description of privacy measures in the Multics operating system" (1967); "Protection and the Control of Information Sharing in Multics" (1974); "Ongoing Research and Development in Information Protection" (1975); "Multics Data Security" (1981); "How the Air Force cracked Multics Security" (1993).
