William Tinsley Keeton (February 3, 1933 – August 17, 1980) was an American zoologist known internationally for his work on animal behavior, especially bird migration, and for his work on millipede taxonomy. He was a well-liked professor of biology at Cornell University in Ithaca, New York and author of a widely used introductory text book, ''Biological Science''. ==Biography== William Keeton was born February 3, 1933 in Roanoke, Virginia, and grew up in Lynchburg. Keeton attended the University of Chicago and received both his Bachelor of Arts and the Bachelor of Science degrees, working under Dr. Alfred E. Emerson. Keeton earned a Master's degree at Virginia Polytechnic Institute (Virginia Tech), during which he revised the millipede genus ''Brachoria''.〔 During his time at Virginia Tech, Keeton met Barbara Orcutt, whom he married in 1958.〔 He moved to Cornell University in 1956 in order to continue his research with millipede systematics for his doctorate, where he studied under Dr. Howard E. Evans. His doctoral research culminated in a monograph on the family Spirobolidae〔Hoffman, Richard L. "William Tinsley Keeton (). 1981. Taken from the website by Geoffroy, Jean-Jaques and Geffard, Didier. "Centre International de Myriapodologie" http://www.myriapodology.org/memoriam/members/keeton-content.html〕 He received his doctorate in 1958 and joined the biology faculty at Cornell University as a biology professor in 1958. Keeton was a noted and well-known Biological Science 101 professor beginning in 1958, so much so that his popularity as a professor earned his class the nickname of the "Keeton course". In addition to his teaching Keeton is known for his work with pigeons and bird orientation and navigation, as he studied pigeon homing behaviors for well over a decade. During his early work at Cornell University the Biological Science Departments were reorganized, and as a result William Keeton moved from the Entomology Department to the newly created Neurobiology and Behavior Department. It was here where he first started his research on pigeon homing, which led him to the discoveries of the effects of the earth's magnetic field, the position of the sun, as well as olfactory navigation and visual cues involved in the process that pigeons use to find their way home. Cornell University built Keeton a loft large enough to house two thousand pigeons that were the subjects of Keeton’s experiments on the behaviors and processes involved in pigeon homing. Both students and faculty at Cornell University, as well as other scientists from around the world came and worked alongside William Keeton in his pigeon loft.〔 William Keeton is also known for his work in writing the biology textbook named ''Biological Science'', that was first published by the W.W. Norton & Company in 1967. It took Keeton approximately five years to write the first edition of the textbook. It went through three editions before his death in 1980. After Keeton's death the textbook was revised for editions 4, 5, and 6 by James L. Gould (and Carol Gould). The textbook was a combination of both botany and zoology. This combination of sciences turned out to be extremely successful in teaching many aspects of biology. The textbook was one of the first that integrated zoology and botany and sought common themes, guided by the process of evolution.〔 Keeton died from heart attack on August 17, 1980 due to a failure of a mechanical heart valve. He was 47 years old.〔 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「William Keeton」の詳細全文を読む スポンサード リンク
