Danny Cohen (born in Israel) is a computer scientist specializing in computer networking. He was involved in the ARPAnet project and helped develop some fundamental applications for the Internet. Cohen is probably best known for his 1980 paper "On Holy Wars and a Plea for Peace"[1] which adopted the terminology of endianness for computing. Cohen served on the computer science faculty at several universities, as well as working in private industry.

Biography

Cohen earned a bachelor's degree in mathematics at the Technion – Israel Institute of Technology in 1963. He spent two years as a graduate student in the math department at the Massachusetts Institute of Technology (MIT), 1965 to 1967.

In 1967, he developed the first real-time visual flight simulator on a general purpose computer and also developed the first real-time radar simulator. Flight simulation work by Cohen led to the development of the Cohen-Sutherland computer graphics line clipping algorithms, created with Ivan Sutherland at Harvard University.[2] He received a PhD from Harvard in 1969 as a student of Sutherland. His thesis was titled: "Incremental Methods for Computer Graphics".[3]

After serving on the computer science faculty at Harvard through 1973, and California Institute of Technology in 1976, Cohen joined the Information Sciences Institute at the University of Southern California to work on a packet-voice project designed to allow interactive, real-time speech over the ARPANet (and the Internet during its early development).[4][5] The Network Voice Protocol project was a forerunner of Voice over Internet Protocol (VoIP). In 1981, he adapted the visual simulator to run over the ARPANet which was an early application of packet switching networks to real-time applications. He started the MOSIS project in 1980.

In 1993, he worked on Distributed Interactive Simulation through several projects funded by the United States Department of Defense (DoD). He prototyped a local area network technology called ATOMIC which was the forerunner of Myrinet.[6] In 1994, Cohen co-founded Myricom (with Chuck Seitz, and others) which commercialized Myrinet. Cohen also started the FastXchange project for electronic commerce and a digital library.

Cohen served on several panels and boards for the US DoD, National Institutes of Health, and United States National Research Council, including 5 years on the USAF Scientific Advisory Board. He served as both a factual and expert witness in patent infringement legal cases about VoIP. Cohen is a commercial pilot with SEL/MEL/SES and Instrument ratings.

In 1993 Cohen received a United States Air Force Meritorious Civilian Service Award. He is a member of the National Academy of Engineering (2006) [7] and an IEEE Fellow (2010).[8]

Since 2001, Cohen was a distinguished engineer for
