Jerome R. Cox Jr.

In 2015, inspired by concepts created by Wesley A. Clark, Cox founded Q-Net Security, Inc., a cyber-security firm. Q-Net Security markets a purpose-built unit that creates an impenetrable barrier between defined endpoints within an existing network. QNS is intelligence-grade, quantum-resistant security.

In 2007, he launched a new company, Blendics, Inc., that provides system-on-chip design tools and services to companies that wish to develop complex, proprietary, low-power integrated circuits and aids in the development of asynchronous computing systems.

The New York Times series on the history of the personal computer had this to say in an article on August 19, 2001, "How the Computer Became Personal": "In the pantheon of personal computing, the LINC, in a sense, came first, more than a decade before Ed Roberts made PC’s affordable for ordinary people. Work started on the Linc, the brainchild of the M.I.T. physicist Wesley A. Clark, in May 1961. Each Linc had a tiny screen and keyboard and comprised four metal modules, which together were about as big as two television sets, set side by side. The machine, a 12-bit computer, included a one-half megahertz processor. Lincs sold for about $43,000 – a bargain at the time – and were ultimately made commercially by Digital Equipment, the first minicomputer company. Fifty Lincs of the original design were built."

Cox, Jonathan S. Turner and Guru Parulkar founded Growth Networks in 1998. Growth Networks produced an advanced networking chip set which focused on high performance switching components for internet routers. He served as Founder and Vice-President of Strategic Planning until the company was acquired by Cisco Systems in 2000.

He is a member of the National Academy of Sciences' Institute of Medicine, and a Fellow of the Acoustical Society of America, the American College of Medical Informatics, and the Institute of Electrical and Electronics Engineers. Cox was the Harold B. and Adelaide G. Welge Professor of Computer Science at Washington University from 1989–1998. In 2011, he was recognized with the School of Engineering & Applied Science’s Dean’s Award. Cox was elected to the 2019 Class of the National Academy of Inventors.

With Jonathan S. Turner and Guru Parulkar, he co-founded the Applied Research Laboratory in 1988.

Cox has also received honors from a variety of professional organizations. He was recognized by Washington University with a Distinguished Faculty Award in 1987 and with the Eliot Society Search Award in 1997. He received a Lifetime Achievement Award from the St. Louis Academy of Science in 2001 and received an Honorary Doctorate of Science from Washington University that same year. In 2011 he was recognized by Washington University with the Chancellor’s Award for Innovation and Entrepreneurship.

Cox is responsible for bringing the Laboratory INstrument Computer, known as LINC – along with its development team including Wesley A. Clark, Severo Ornstein, and Charles Molnar – to Washington University in 1964. LINC, which was developed at Massachusetts Institute of Technology’s Lincoln Laboratory in 1962, is a contender for the title of the first personal computer because it can be managed by a single individual.

In 1964, Cox founded the Biomedical Computer Laboratory, an organization dedicated to the introduction of small computers to biomedical research. His pioneering work in radiation treatment planning paved the way for systems in worldwide operation. His research team developed computer methods for reconstructing images from CT and PET scanners that aid in the diagnosis of cancers and cardiovascular disease. His innovations were instrumental in developing early monitors for heart rhythm disturbances. He also worked on computer applications in mapping the human genome and in electronic radiology.

In 1964, Cox brought the LINC (the Laboratory INstrument Computer) and its development team to Washington University from MIT’s Lincoln Laboratory. This team included Wesley A. Clark, Severo Ornstein, and Charles Molnar. The LINC is considered by some to be the first minicomputer, and a forerunner to the personal computer.

Cox patents including the following : US Patent 3,159,832 (1964) "Anti-Collision Device for Aircraft"; US Patent 3,976,885 (1976) "Tomography System Having Concurrent Compound Axial Scanning"; US Patent 7,106,693 (2006) "Method and Apparatus for Pacing the Flow of Information Sent from a Device"; US Patent 7,243,255 B2 (2007) "Design of Instantaneously Restartable Clocks and Their Use Such as Connecting Clocked Subsystems Using Clockless Sequencing Networks"; and US Patent 9,614,669 (2017) "Secure Network Communications Using Hardware Security Barriers".

In 1955, Cox was recruited by Hallowell Davis to leave Boston and come to Central Institute for the Deaf in St. Louis. Davis, Director of Research at CID, challenged Cox to implement an idea for measuring hearing in infants. In 1961, Cox and his graduate student, A. M Engrebretson, designed and built a special-purpose digital computer used by Davis to pioneer the field of early detection of deafness. This research has since led to mandated screening tests for newborn infants throughout the United States.

Beginning in 1955, Cox was an Assistant Professor, Associate Professor, and then Professor of Electrical Engineering. In 1975 he became the founding chairman of the School of Engineering and Applied Science’s first Department of Computer Science and guided the department’s development and growth for more than 15 years. Cox was instrumental in building a department that has an international reputation for biomedical computing applications and computer networking.

Cox began his career in 1952 as the director of the now-shuttered Liberty Mutual Research Institute for Safety in Hopkinton, Massachusetts. His research centered on industrial noise exposure and the potential impact on worker hearing loss. This work included the first longitudinal study of audiometric histories of employees in industrial noise.

Cox married Barbara (Bobby) Jane Lueders in September 1951. They were married until her death in 2006. Cox has three children, eight grandchildren, and four great-grandchildren. He lives in Sunset Hills, a suburb of St. Louis, Missouri.

After serving in the U.S. Army from 1943–1944, he attended the Massachusetts Institute of Technology, where he earned bachelor's (1947), master's (1949), and doctoral degrees (1954) in electrical engineering, with an emphasis in acoustics.

Jerome Rockhold Cox Jr. (born May 24, 1925) is an American computer pioneer, scientist, and entrepreneur. He contributed significantly to the areas of biomedical computing, multimedia communications, and computer networking. He was the founding chairman of the Department of Computer Science at Washington University in St. Louis. He is a senior professor emeritus of Computer Science at Washington University (1999 -), as well as Founder and President of Blendics, Inc., (2007 -) and Q-Net Security. Inc (2015 -). In 1998, Cox collaborated with colleagues Jonathan S. Turner and Guru Parulkar in founding Growth Networks (acquired by Cisco Systems in 2000).

Cox was born in Washington, D.C. in May 1925. Six years later, his parents, Jerome R. Cox, Sr., and Jane Mills Cox moved to South Bend, Indiana, where he grew up and learned to love mathematics. Cox gravitated to his professional path at a young age. When he was 11 years old, he secretly took apart his radio to see how it worked.
