Berwind P. Kaufmann (1897-1975) was an important American biologist. After starting off as a botanist looking at plant chromosomes, Berwind Kaufmann ended up making pioneering contributions to three principal fields of basic cytogenetics: * the formation of chromosomal rearrangements by exposure to ionizing radiation; * the identification of specialized regions (the nucleolar organizer and heterochromatic regions) of the somatic chromosomes of the fruit fly Drosophila; * and the determination of the biochemical composition of both plant and animal chromosomes using purified enzymes.() ==Career== Kaufmann was born in Philadelphia, Pennsylvania. He stayed in his hometown and attended the University of Pennsylvania, receiving his B.Sc. degree in 1918, M.A. in 1920, and Ph.D. in 1925. His doctoral thesis dealt with the structure of the chromosomes of Tradescantia and led to a major publication. In 1926 he went to Southwestern College, Memphis, Tennessee, where he taught biology. He left in 1929 to become professor and chairman of the Department of Botany at the University of Alabama. He took a sabbatical leave in 1932-1933 at the California Institute of Technology. He left Alabama in 1936 to go to the Department of Genetics of the Carnegie Institution of Washington at the Cold Spring Harbor Laboratory on Long Island, New York where he happily remained for 25 years, the balance of his career. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Berwind P.
