Timeline

1932

Duffin obtained a BSc in physics at the University of Illinois, where he was elected to Sigma Xi in 1932.

1935

He stayed at Illinois for his PhD, which was advised by Harold Mott-Smith and David Bourgin, producing a thesis entitled Galvanomagnetic and Thermomagnetic Phenomena (1935).

Duffin lectured at Purdue University and Illinois before joining the Carnegie Institute in Washington, D.C. during World War II.

His wartime work was devoted to the development of navigational equipment and mine detectors.

1941

In 1941, Duffin and A. C. Schaeffer put forward a conjecture in metric diophantine approximation which was resolved in 2020 by James Maynard and Dimitris Koukoulopoulos.

1946

In 1946, he became professor of mathematics at Carnegie Mellon University.

He wrote a letter of recommendation

to Princeton University for John Forbes Nash, Jr., later a Nobel laureate.

1949

In 1949, Duffin and his student Raoul Bott developed a generalized method of synthesising networks without transformers which were required in earlier methods.

1967

In 1967 Duffin joined with Clarence Zener and Elmor Peterson to write Geometric Programming which developed a branch of mathematical programming by introducing a generalization of polynomials to posynomials for engineering applications.

Impressed with its innovations, a reviewer wrote, "common sense, ingenuity and originality in applying first principles are still competitive with other creative forms of the intellect."

The methods of geometric programming are sometimes adapted for convex optimization.

1972

Duffin was inducted to the National Academy of Sciences in 1972 and to the American Academy of Arts and Sciences in 1984.

Duffin was also a consultant to Westinghouse Electric Corporation.

1996

Richard James Duffin (1909 – October 29, 1996) was an American physicist, known for his contributions to electrical transmission theory and to the development of geometric programming and other areas within operations research.

2002

He was elected to the 2002 class of Fellows of the Institute for Operations Research and the Management Sciences.
