biography

Edward Lynn Kaplan was born on May 11, 1920 in Philadelphia. His parents were Eugene V. Kaplan (1887–1977) and Frances Rhodes Kaplan (1891–1978). In 1937 he graduated from Swissvale High School in Swissvale, Pennsylvania. He then attended the Carnegie Institute of Technology from 1937 to 1941, where he graduated with a bachelor's degree in mathematics. Three times - in 1939, 1940 and 1941 - he was one of five winners of the US-wide William Lowell Putnam Mathematical Competition , organized by the American Mathematical Association . He was offered the Westinghouse’s Putnam Prize Scholar Scholarship in Mathematics at Harvard , but could not accept it because of military service. Kaplan was a member of three scientific societies: Phi Kappa Phi, Sigma Xi and the Engineering Society Tau Beta Phi.

From June 1941 to August 1948, Kaplan worked at the United States Naval Ordinance Laboratory , Whiteoak, Maryland . His boss during this time was John V. Atanosoff , the discoverer of the first electronic computer. After the war, he enrolled in the PhD -Studiengang mathematics at Princeton on the side of the later Nobel Prize winner John Nash, Jr one. Kaplan and Nash had the same tutor at the Carnegie Institute of Technology , Professor Joseph B. Rosenbach . Kaplan finished his PhD dissertation “Infinite permutations of stationary random sequences” in November 1950. Members of the examination committee included John W. Tukey and Samuel S. Wilks .

From 1950 to 1957 Kaplan worked for Bell Telephone Laboratories in Murray Hill, NJ. In 1957 he moved to the Computation Division of the Lawrence Radiation Laboratory in Livermore, California, where he participated in the Monte Carlo simulation for the development of the hydrogen bomb. In the fall of 1961, Kaplan joined the math department of Oregon State University in Corvallis, Oregon until the end of his professional career. He died on September 20, 2006 at the age of 86 in Corvallis after a prolonged illness.
