Danny Cohen (born in Israel) is a member of the National Academy of Engineering (2006) [1] and an IEEE Fellow (2010).[2] In 1993 Cohen received a USAF (United States Air Force) Meritorious Civilian Service Award.

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. In 1981, he adapted the visual simulator to run over the ARPANet (the forerunner to the Internet) which was the first application of packet switching networks to real-time applications.

Starting in 1973, Cohen led several projects on real-time interactive applications over the ARPANet and the Internet, such as packet-voice (also known as Voice over Internet Protocol) and packet-video.

In 1967, flight simulation work by Cohen led to the development of the Cohen-Sutherland computer graphics line clipping algorithms, created with Ivan Sutherland.[3]

After serving on the computer science faculty at Harvard University (1969–1973) and Caltech (California Institute of Technology) in 1976, Cohen joined USC/ISI (University of Southern California/Information Sciences Institute) to work on a project designed to allow interactive, real-time speech over the ARPANet. Cohen worked at USC/ISI (1973–1993), where he started many network related projects, including Packet-Voice, Packet-Video, and Internet Concepts. He started the MOSIS project in 1980. Cohen also started the FastXchange project (Electronic commerce), Digital Library, and ATOMIC which was the forerunner of Myrinet, a high-performance system area network. In 1993, he worked on Distributed Interactive Simulation through several projects funded by DoD (United States Department of Defense). In 1994, Danny co-founded Myricom (with Chuck Seitz, et al.) which commercialized Myrinet.

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

Cohen is probably best known for his 1980 paper "On Holy Wars and a Plea for Peace"[4] which adopted the terminology of endianness for computing.

Education and early work

Danny earned a bachelor's degree in mathematics at the Technion (Technion – Israel Institute of Technology) in 1963 and a PhD from Ivan Sutherland at Harvard in 1969. His thesis was titled: "Incremental Methods for Computer Graphics".[5] Danny has served on the computer science faculty at Harvard, Technion, and Caltech. He also spent two years as a graduate student in the math department at the Massachusetts Institute of Technology (MIT), 1965-1967.

Current work

Since 1991 Danny Cohen has been a Distinguished Engineer for Sun Microsystems [6] working on very fast communication over short distances, using optical and electrical signaling, in Sun's CTO (Chief technical officer) organization.

Danny is also an Adjunct Professor of Computer Science at USC.[7]
