Colin Pittendrigh (October 13 1918 in Whatley Bay, England, died March 19, 1996 in Bozeman, Montana) was a US-American biologist (of English parentage) and a co-creator of chronobiology.
Life
[edit]Colin Pittendrigh was born in 1918 in northeastern England (today Tyne and Wear) and studied at the University of Durham. He married and had two children. During the Second World War he was sent by the British Government to Trinidad in order to develop a method of protecting British troops from malaria.
After the war, Pittendrigh attended Columbia University in order to write his doctoral thesis on the evolutionary geneticist Theodosius Dobzhansky. In 1950 he became a U.S. citizen. He graduated from Stanford University in 1968. His favorite hobby was fly-fishing.
Work
[edit]During his time in Trinidad in the Second World War, he was already beginning to develop an interest in animals' orientation to time. This interest led him to pursue his work on the subject at Princeton. His work demonstrated that biological time management and the observable rhythms of animals behavior through 24 hours are endogenous, and not caused by signals from their environment, as many scientists thought. He developed an oscillatory model and described the characteristics of an internal pacemaker and its entrainment to the daily cycle of light and dark.
Together with Jürgen Aschoff he laid the groundwork for today's understanding of chronobiology; for example, human wake/sleep cycles, hibernation, the navigation of animals, and jetlag. Pittendrigh also established the concept of teleonomy, a quality determined through objective principles as described in the book Behavior and Evolution (1958, edited by Anne Roe and George Gaylord Simpson). Pittendrigh applied this concept to knowledge of cellular control mechanisms. He purposefully positioned his concept of teleonomy against the concept of teleology, which he believed to be an unscientific and idealistic approach to the interpretation of biological control mechanisms. A teleonomic act or characteristic is one which owes its usefulness to the workings of a program.
