John van Geen (August 17, 1929 – June 6, 2000) [1] was a researcher at the Stanford Research Institute (now SRI International) who was known for his advances in the acoustically coupled modem.
Van Geen was born in 1929 in Etterbeek, Belgium. In 1953, he received a degree in electrical and radio engineering from Brussels University. [1]
In 1959, Van Geen joined the Stanford Research Institute. Van Geen's enhancements to the modem in 1966 allowed the designed receiver to detect data (in the form of bits) and distinguish it from background noise more reliably than any previous models. [2]
His advancements also led to the release of the first public modem. It appealed to the public because it mimicked the characteristics of a standard telephone handset at that time. [3]
Van Geen retired from the Stanford Research Institute in 1989 after 30 years there. [1] He died on June 6, 2000, in Monterey Peninsula. [1]
Douglas Carl Engelbart was an American engineer and inventor, and an early computer and Internet pioneer. He is best known for his work on founding the field of human–computer interaction, particularly while at his Augmentation Research Center Lab in SRI International, which resulted in creation of the computer mouse, and the development of hypertext, networked computers, and precursors to graphical user interfaces. These were demonstrated at The Mother of All Demos in 1968. Engelbart's law, the observation that the intrinsic rate of human performance is exponential, is named after him.
In computing, time-sharing is the sharing of a computing resource among many users at the same time by means of multiprogramming and multi-tasking.
In telecommunications, an acoustic coupler is an interface device for coupling electrical signals by acoustical means—usually into and out of a telephone.

Raytheon BBN is an American research and development company, based next to Fresh Pond in Cambridge, Massachusetts, United States.
The Advanced Research Projects Agency Network (ARPANET) was the first wide-area packet-switched network with distributed control and one of the first networks to implement the TCP/IP protocol suite. Both technologies became the technical foundation of the Internet. The ARPANET was established by the Advanced Research Projects Agency (ARPA) of the United States Department of Defense.
David Packard was an American electrical engineer and co-founder, with Bill Hewlett, of Hewlett-Packard (1939), serving as president (1947–64), CEO (1964–68), and chairman of the board of HP. He served as U.S. Deputy Secretary of Defense from 1969 to 1971 during the Nixon administration. Packard served as president of the Uniformed Services University of the Health Sciences (USU) from 1976 to 1981 and chairman of its board of regents from 1973 to 1982. He was a member of the Trilateral Commission. Packard was the recipient of the Presidential Medal of Freedom in 1988 and is noted for many technological innovations and philanthropic endeavors.
John McCarthy was an American computer scientist and cognitive scientist. He was one of the founders of the discipline of artificial intelligence. He co-authored the document that coined the term "artificial intelligence" (AI), developed the programming language family Lisp, significantly influenced the design of the language ALGOL, popularized time-sharing, and invented garbage collection.
John Leroy Hennessy is an American computer scientist, academician and businessman who serves as Chairman of Alphabet Inc. Hennessy is one of the founders of MIPS Computer Systems Inc. as well as Atheros and served as the tenth President of Stanford University. Hennessy announced that he would step down in the summer of 2016. He was succeeded as President by Marc Tessier-Lavigne. Marc Andreessen called him "the godfather of Silicon Valley."
Max Vernon Mathews was a pioneer of computer music.
SRI International (SRI) is an American nonprofit scientific research institute and organization headquartered in Menlo Park, California. The trustees of Stanford University established SRI in 1946 as a center of innovation to support economic development in the region.
"The Mother of All Demos" is a name retroactively applied to a landmark computer demonstration, given at the Association for Computing Machinery / Institute of Electrical and Electronics Engineers (ACM/IEEE)—Computer Society's Fall Joint Computer Conference in San Francisco, by Douglas Engelbart, on December 9, 1968.
Paul Baran was a Polish-American engineer who was a pioneer in the development of computer networks. He was one of the two independent inventors of packet switching, which is today the dominant basis for data communications in computer networks worldwide, and went on to start several companies and develop other technologies that are an essential part of modern digital communication.
NLS, or the "oN-Line System", was a revolutionary computer collaboration system developed in the 1960s. Designed by Douglas Engelbart and implemented by researchers at the Augmentation Research Center (ARC) at the Stanford Research Institute (SRI), the NLS system was the first to employ the practical use of hypertext links, the mouse, raster-scan video monitors, information organized by relevance, screen windowing, presentation programs, and other modern computing concepts. It was funded by ARPA, NASA, and the US Air Force.
Stuart K. Card, an American researcher and retired Senior Research Fellow at Xerox PARC, is considered to be one of the pioneers of applying human factors in human–computer interaction. With Jock D. Mackinlay, George G. Robertson and others he invented a number of Information Visualization techniques. He holds numerous patents in user interfaces and visual analysis.
John Mathew Cioffi is an American electrical engineer, educator and inventor who has made contributions in telecommunication system theory, specifically in coding theory and information theory. Best known as "the father of DSL," Cioffi's pioneering research was instrumental in making digital subscriber line (DSL) technology practical and has led to over 400 publications and more than 100 pending or issued patents, many of which are licensed.
Stephen R. Palumbi is the Jane and Marshall Steel Jr. Professor in Marine Sciences at Stanford University at Hopkins Marine Station. He also holds a Senior Fellowship at the Stanford Woods Institute for the Environment.
George Eber MacGinitie was an American marine biologist and a professor at the California Institute of Technology. He married the marine biologist Nettie Murray MacGinitie and the couple conducted research together and helped produce films on marine life.
