Researcher and professor
Member, 39; died 5 July
Mathematics professor Igor Isayev headed a group researching vibratory-diagnostic signals at the Karpenko Physico-Mechanical Institute at the National Academy of Sciences of Ukraine, in Kiev.
He began his career as a researcher in 2004 in the mathematics and statistics faculty at the University of Cambridge. He worked in many areas, including stochastic analysis of probability systems, problems of electromagnetic field reconstruction, and nonstationary signals and processes applied to nondestructive testing control. He left Cambridge in 2008 to be a visiting lecturer at the University of Rennes, France.
Isayev earned a master’s degree in mathematics in 1992 from the Ivan Franko National University of L’viv, Ukraine. He received a Ph.D. in mathematical modeling and numerical methods in 1998 from the Pidstryhach Institute of Applied Problems of Mechanics and Mathematics, also in L’viv.
Professor of engineering
Life Fellow, 94; died 12 December
Richard Webb was a practicing engineer and an electrical engineering professor. He began his career in Denver at Mountain States Telephone and Telegraph, now part of Qwest Communications, as a telephone engineer. He became a professor of electrical engineering, first at Iowa State College, in Ames, and then at the University of Denver. He went on to serve as senior research engineer at the Denver Research Institute. From 1962 to 1982, he was a visiting lecturer at the University of Colorado, Denver.
Webb earned a bachelor’s degree in physics in 1937 from the University of Denver; a master’s degree in electrical engineering from Princeton in 1949; and a Ph.D. in 1951 from Purdue University, West Lafayette, Ind.
John V. Harrington
MIT professor and research director
Life Fellow, 90; died 13 December
John V. Harrington spent a long career as a researcher in space and military technologies, and he was the first director of the MIT Center for Space Research (now the Kavli Institute for Astrophysics and Space Research).
He enlisted in the U.S. Navy during World War II, and became a lieutenant in 1942. He was an electronics officer aboard several destroyers in the Pacific and was responsible for overseeing shipboard radar defense systems, a nascent technology at the time.
After the war, Harrington joined the U.S. Air Force Cambridge Research Laboratory in 1946 at Hanscom Air Force Base in Massachusetts, where he explored radar, space, and communications technologies. He also oversaw the development of radar data processing and transmission equipment, including the earliest data transmission modems. In 1958, he joined the radio physics division at MIT’s Lincoln Laboratory, where he served as director until 1963.
That year he also became a professor at MIT in the aeronautics and astronautics and electrical engineering departments, as well as the first director of the MIT Center for Space Research. He left MIT in the early 1970s to join the Communications Satellite Corp. (Comsat), where he served as senior vice president of research and development. He later was director of Comsat Laboratories in Germantown, Md., until he retired in 1984.
Harrington earned a bachelor’s degree in electrical engineering in 1940 from the Cooper Union, in New York City. He received a master's degree in electrical engineering in 1948 from the Polytechnic Institute of Brooklyn, also in New York, and a Ph.D. in 1958 from MIT.
Aerospace product designer
Life Senior Member, 84; died 24 December
Wilbur Carrington spent most of his career working in radio and aerospace electronics.
He was drafted into the U.S. Army in 1942, and he was a radio operator in the Army Signal Corps. In 1950, he moved to Grand Rapids, Mich., and began his electrical engineering career in aerospace product design and development at Lear Inc. (now known as Smiths Industries, a part of General Electric). His contributions included advances in aeronautic and missile-navigation instruments such as accelerometers, gyroscopes, and fiber-optic systems. He retired in 1987.
Carrington earned a bachelor’s degree in electrical engineering in 1950 from the University of Michigan, Ann Arbor.
