Bradford Keeney, Ph.D. (3 April 1951) is an American psychotherapist, ethnographer, and cybernetician. Author of more than thirty books in the fields of psychotherapy, cybernetics, and ethnographies of healing traditions, many of his works are considered classics in their fields. Bradford Keeney, born in Granite City, Illinois, grew up in Smithville, Missouri. In May 1969, he won first place at the international science fair with a project called An Experimental Study of the Effects of Hydrocortisone, Insulin, and Epinephrine on the Glycogen Content of Hepatic Tissues Perfused in Vitro. This award earned him a scholarship to M.I.T. where he was first introduced to cybernetics and systems thinking. Fascinated by cybernetics, Keeney sought out Gregory Bateson, one of the world s leading cyberneticians, who became his friend and mentor. Keeney s doctoral dissertation (Purdue University, 1981) became the book Aesthetics of Change (1983), considered a seminal work in cybernetic theory and heralded by the likes of cybernetician and systems theorist Heinz von Foerster.
