Short description: American educator
Charles Laurie Dolph (August 27, 1918 – June 1, 1994) was an American mathematician known for his research in applied mathematics and engineering.[1][2]
Biography
Dolph graduated from the University of Michigan with A.B. in 1939 and from Princeton University with M.A. in 1941 and Ph.D. in 1944. His thesis advisor was Salomon Bochner.[3] Dolph was from 1943 to 1944 a physicist in the U.S. Naval Research Laboratory and from 1944 to 1945 an ensign in the U.S. Navy.[2]
While serving with the U.S. Navy during World War II, Dolph was part of a team of scientists who developed an IFF (“Identification: Friend or Foe”) radar system, which is still used by military and civilian aircraft today. Dolph’s early research on antenna arrays was instrumental to the founding of Hughes Electronics.[1]
From 1945 to 1946 Dolph worked for Michigan Bell Telephone Laboratories. In 1946 he joined the University of Michigan faculty as a lecturer with a joint appointment in the department of mathematics and in the department of engineering research at the Engineering Research Institute. At the University of Michigan's department of mathematics he became in 1947 an assistant professor, in 1954 an associate professor, and in 1960 a full professor, retiring in 1988 as professor emeritus.[2]
His research covered a wide range of problems in applied mathematics—including antenna theory, compressible fluid flow, shock problems, stochastic processes, plasma physics, atmospheric science, scattering theory, singular expansion methods and non-self-adjoint operators.[1]
In 1982 Dolph, an Ann Arbor native, and his first wife donated the land for the Dolph Park Nature Area to the City of Ann Arbor. The land, consisting of 57 acres with 2 lakes, was originally owned by his parents.[1][4]
He directed four doctoral theses[3] and was three times a visiting professor at German universities. He was an associate editor for the Journal of Mathematical Analysis and Applications.[2]
In 1944 in New Jersey, Dolph married Marjorie Louise Tibert (1918–2010). They divorced after three of their four children died,[5] and Dolph remarried. He died in 1994.
