He was a Jacob Gould Schurman Professor of Chemical Ecology at Cornell University, and Director of the Cornell Institute for Research in Chemical Ecology (CIRCE). He was a world authority on animal behavior, ecology, and evolution, and, together with his Cornell colleague, Jerrold Meinwald, is one of the pioneers of chemical ecology, the discipline dealing with the chemical interactions of organisms. He was author or co-author of some 400 scientific articles and 7 books.

Personal life

Thomas Eisner was born on June 25, 1929 in Berlin, Germany. His father Hans Eisner, of Jewish origin, was the chemist and a coworker of Fritz Haber at the Kaiser Wilhelm Institute for Electrochemistry in Berlin, later held a chair for chemistry at Cornell. His mother was an artist Margarete Heil-Eisner. Escaping the Nazi regime, the family moved to Barcelona and, following the civil war there, to Uruguay. The Eisners came to the U.S. in 1947.^[2]
Thomas Eisner became a naturalized American citizen. He applied to Cornell University as an undergraduate but was rejected. He received his B.S. and Ph.D. degrees from Harvard University, and he later joined Cornell’s entomology faculty in 1957. He married Maria Eisner, who was a member of his lab. In 1964, he helped found the Department of Neurobiology and Behavior, where he worked until his death on March 25, 2011 of Parkinson's disease.^[1]
In addition to his academic work, he was a passionate nature photographer^[3] and videographer. His film Secret Weapons won the Grand Award at the New York Film Festival and was named Best Science Film by the British Association for the Advancement of Science. He was also an avid pianist and occasional conductor.

Work

Thomas's Eisner's main body of work was in chemical ecology, primarily studying the chemical defenses of insects against predation. Some of his most famous work is that of the Bombardier beetle, which he discovered creates a chemical reaction within its body to shoot boiling noxious liquid from a nozzle in its abdomen.
A field biologist with working experience on four continents, he was also an active conservationist. He served on the Board of Directors of the National Audubon Society, the National Scientific Council of the Nature Conservancy, and the World Resources Institute Council. He was a past president of the American Society of Natualists, and chairman of the Biology Section of the American Association for the Advancement of Science. He played a key role in initiating the Congressional Fellow Program in Washington DC, and in efforts to preserve wilderness areas in Florida and Texas.
He was also member of the National Academy of Sciences, the American Academy of Arts and Sciences, and the American Philosophical Society, he received numerous honors, including the Tyler Prize for Environmental Achievement, the Harvard Centennial Medal, the National Medal of Science in 1994^[4] and the Lewis Thomas Prize for Writing about Science (2005) and held honorary degrees from Sweden, Germany, Switzerland, and the United States. He was a foreign fellow of The Royal Society, and a member of the Deutsche Akademie der Naturforscher Leopoldina and Academia Europaea.
In 2008 Eisner was awarded the John J. Carty Award from the National Academy of Sciences.^[5]
