Fritz Ursell

Education Ursell came to England as a Jewish refugee in 1937 from Germany, and was educated at Marlborough College. From 1941 to 1943 he studied at Trinity College, Cambridge, graduating with a bachelor degree in mathematics.

Career At the end of 1943 Ursell joined the Admiralty as a part of a team—headed by George Deacon —whose task was to formulate rules for forecasting waves for the allied landings in Japan. Their findings have become the basis of modern wave-forecasting. Ursell stayed in the Admiralty until 1947. In 1947 he was appointed to a post-doctoral fellowship in applied mathematics at Manchester University without a doctorate. In 1950 he returned to Cambridge as lecturer. There he met G. I. Taylor. In 1957 he spent a year at Massachusetts Institute of Technology, having been invited by Arthur Ippen. In 1961 Ursell moved back to Manchester.

In 1994 Ursell was awarded the Gold Medal of the Institute of Mathematics and its Applications in recognition of his "outstanding contributions to mathematics and its applications over a period of years".

Scientific work In 1957 he published together with Clive R. Chester and Bernard Friedman a classic paper that introduced a method to find asymptotic expansions for contour integrals with coalescing saddle points. The method is now called method of Chester–Friedman–Ursell.

Personal life Fritz Ursell was married to Katharina Renate Zander in 1959. They had two daughters.
