Jon Postel
American computer scientist (1943–1998)
Jonathan Bruce Postel (; August 6, 1943 – October 16, 1998) was an American computer scientist who made many significant contributions to the development of the Internet, particularly with respect to standards. He is known principally for being the editor of the Request for Comment (RFC) document series, for Simple Mail Transfer Protocol (SMTP), and for administering the Internet Assigned Numbers Authority (IANA) until his death.
During his lifetime he was referred to as the "god of the Internet" for his comprehensive influence; Postel himself noted that this "compliment" came with a barb, the suggestion that he should be replaced by a "professional," and responded with typical self-effacing matter-of-factness: "Of course, there isn’t any 'God of the Internet.' The Internet works because a lot of people cooperate to do things together."
Career
Postel attended Van Nuys High School with Steve Crocker and Vint Cerf, and then UCLA where he earned his B.S. (1966) as well as his M.S. (1968) in Engineering. There he completed his Ph.D. in computer science in 1974, with Dave Farber as his thesis advisor.
Postel started work at UCLA on 23 December 1969 as a Postgraduate Research Engineer (I) where he was involved in early work on the ARPANET. He was involved in the development of the Internet domain system and, at his instigation, Vint Cerf and Bob Kahn developed a second set of protocols for handling data between networks, which is now known as Internet protocol suite. Together with Cerf and Steve Crocker, Postel worked on implementing most of the ARPANET protocols. Cerf would later become one of the principal designers of the TCP/IP standard, which works because of the sentence known as Postel's Law.
Postel worked with ARPANET until 24 August 1973 when he left to join MITRE Corporation. He assisted with Network Information Center, which was being set up at SRI by Elizabeth Feinler. In March 1977, he joined the Information Sciences Institute at the University of Southern California as a research scientist.
This brief starts where responsible research should: with the source description of “Jon Postel” as american computer scientist (1943–1998). Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the people & ideas register because the source frames it as american computer scientist (1943–1998). Its deeper value depends on whether names, dates, institutions and citations support that framing.
Biographical claims are most persuasive when dates, appointments and relationships can be traced to records created close to the events described. The source revision retrieved here is dated Sep 1, 2026. The linked authority identifier is Q92623. VIAF identifies the subject as 52548963. The Library of Congress control number is n88619424. 4 of 4 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1943, 1998, 1966 and 1968.
Later biographies can compress uncertainty and repeat inherited reputations, so apparently settled claims may still require comparison. 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.
How to read it
Read biographical claims against dates, named institutions and the cited references. Distinguish a subject’s later reputation from evidence produced during their lifetime.
- Establishing names and roles
- Building a first chronology
- Locating cited institutions
Personal papers, civil or court records, institutional files and the scholarship cited by the source.
Three-step research path
- Establish the record: confirm the title “Jon Postel”, its source revision and the description used here.
- Expand the search: follow Jon Postel primary sources, Jon Postel archive and Postel research across catalogues and specialist indexes.
- Test the account: compare the strongest cited source with the responsible institution’s current record and note any disagreement.
