Lewis Thomas (November 25, 1913 – December 3, 1993) was an American physician, poet, etymologist, essayist, administrator, educator, policy advisor, and researcher.
His autobiography, The Youngest Science: Notes of a Medicine Watcher, is a record of a century of medicine and the changes which occurred in it. He also published a book on etymology titled Et Cetera, Et Cetera, poems, and numerous scientific papers.
Many of his essays discuss relationships among ideas or concepts using etymology as a starting point. Others concern the cultural implications of scientific discoveries and the growing awareness of ecology. In his essay on Mahler's Ninth Symphony, Thomas addresses the anxieties produced by the development of nuclear weapons.[3] Thomas is often quoted, given his notably eclectic interests and superlative prose style.
