Timeline

1909

John Williams Calkin (11 October 1909, New Rochelle, New York – 5 August 1964, Westhampton, New York) was an American mathematician, specializing in functional analysis.

The Calkin algebra is named after him.

1922

Upon his death he was survived by his widow, Emilienne Calkin (1922–2000), and his son, Brant Calkin (born 1934), from a previous marriage (to Eileen Calkin).

Brant Calkin is an environmental activist in New Mexico and Utah and former president of the Sierra Club.

1933

Calkin received his bachelor's degree from Columbia University in 1933 and his master's degree in 1934 and Ph.D. in 1937 from Harvard University.

1937

His doctoral dissertation Applications of the Theory of Hilbert Space to Partial Differential Equations; the Self-Adjoint Transformations in Hilbert Space Associated with a Formal Partial Differential Operator of the Second Order and Elliptic Type ) was supervised by Marshall H. Stone. In the dissertation, Calkin acknowledges useful discussions with John von Neumann. At the Institute for Advanced Study, Calkin was a research assistant for the academic year 1937–1938 (working with Oswald Veblen and von Neumann) and in the first eight months of 1942. From 1938 to 1942 he was an assistant professor at the University of New Hampshire and then at Chicago's Illinois Institute of Technology. During the late 1930s and early 1940s he wrote several important papers on operator theory and its applications to partial differential equations.

"During World War II Calkin was part of a mine warfare operations analysis group with J.L. Doob, J. von Neumann, and M.H. Stone. Von Neumann and Calkin worked on shock waves and damage by explosives; they were sent to England to learn of the progress under way there. When it appeared that their special knowledge would be useful for the Manhattan Project, they moved to Los Alamos."

1946

From Los Alamos, Calkin went in 1946 as a Guggenheim Fellow to the California Institute of Technology.

1958

"In 1958, he accepted a consulting appointment at New York University and at Brookhaven National Laboratory and, in 1961, was named head, and then chairman of the Applied Mathematics Department."

1960

He later taught at the Rice Institute (renamed Rice University in 1960), before he returned in 1949 to Los Alamos Scientific Laboratory as a member of the theoretical division.

There he worked on the development of the H-bomb.
