 johns frederick (jeff) rulifson (born august 20, 1941) is an american computer scientist. ==early life and education== johns frederick rulifson was born august 20, 1941 in bellefontaine, ohio. his father was erwin charles rulifson and mother was virginia helen johns. he married janet irving on june 8, 1963 and had two children. rulifson graduated with a bs in mathematics from the university of washington in 1966. ==career== rulifson joined the augmentation research center, at the stanford research institute (now sri international) in 1966. he led the software team that implemented the on-line system (nls), a system that foreshadowed many future developments in modern computing and networking. although douglas engelbart was the founder and leader of arc, rulifson's innovative programming was essential to the realization of engelbart's vision. rulifson was sri's representative to the "network working group" in 1968, which led to the first connection on the arpanet. he described the decode-encode language (del), which was designed to allow remote use of nls over arpanet. although never used, the idea was small "programs" would be down-loaded to enhance user interaction. this concept was fully developed in sun microsystems's java programming language almost 30 years later.{{citation |title= 30 years of rfcs |author= rfc editor, et a. |w
