Jack Kiefer (statistician)
Jack Carl Kiefer was an American statistician.Biography
Jack Kiefer was born on January 25, 1924, in Cincinnati, Ohio, to Carl Jack Kiefer and Marguerite K. Rosenau. He began his undergraduate studies at the Massachusetts Institute of Technology in 1942, but left after one year, taking up a position as first lieutenant in the United States Air Force during World War II. In 1946, he returned to MIT, graduating with bachelor's and master's degrees in economics and engineering in 1948 under the supervision of Harold Freeman. He then began graduate studies at Columbia University, under the supervision of Abraham Wald and Jacob Wolfowitz, receiving his Ph.D. in mathematical statistics in 1952. While still a graduate student, he began teaching at Cornell University, remaining there until 1979, when he retired from Cornell and accepted a new position as Miller Research Professor in the Department of Statistics and Mathematics at the University of California, Berkeley. In 1957, he married Dooley Sciple, a former undergraduate student of his at Cornell, with whom he had two children. Kiefer died of a heart attack in Berkeley, California on August 10, 1981.Awards and honors
Kiefer was a Fellow of the American Statistical Association and of the Institute of Mathematical Statistics, a member of the American Academy of Arts and Sciences and of the United States National Academy of Sciences. From 1969–1970 he was president of the Institute of Mathematical Statistics. In 1973, Kiefer and Michael Fisher were the first two Cornell faculty elected as Horace White Professors.Contributions
Much of Kiefer's research was on the design of experiments; the American Statistician obituary calls him "undoubtedly the foremost worker in optimal experimental design". However, he also made significant contributions to other areas of statistics and optimization, including the introduction of golden section search the Dvoretzky–Kiefer–Wolfowitz inequality and the Bahadur-Ghosh-Kiefer representation.
