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
University of Washington
in 1966.


Rulifson joined the Augmentation Research Center , at the Stanford Research Institute (now SRI International
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
Douglas Engelbart
was the founder and leader of ARC, Rulifson's innovative programming was essential to the realization of Engelbart's vision.

Rulifson was the 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
Sun Microsystems
's Java programming language almost 30 years later, as applets .

Rulifson earned a doctorate in computer science from Stanford University in 1973. Rulifson left SRI to join the System Sciences Laboratory (SSL) within Xerox PARC
Xerox PARC
in 1973. While at PARC, he worked on implementing distributed office systems. He worked for ROLM in 1980 as an engineering manager. In 1985 he joined the company Syntelligence in Sunnyvale, California
Sunnyvale, California
. He worked for Sun Microsystems Laboratories , in Ivan Sutherland
Ivan Sutherland
's lab since 1987. Sun was purchased by Oracle Corporation
Oracle Corporation
in 2010.


In 1990, Rulifson won the Association for Computing Machinery
Association for Computing Machinery
's Software System Award for implementing groundbreaking innovations such as hypertext , outline processors, and video conferencing .

In 1994, he was inducted as a Fellow of the Association for Computing Machinery.
