Pittendrigh died from cancer on Tuesday, March 19, 1996, at his home in Bozeman, Montana. He has been regarded as one of the most influential figures in the field, and his research influences the field of chronobiology even after his death. The Society for Research on Biological Rhythms holds biennial lectures named in honor of Pittendrigh and Aschoff.


Pittendrigh retired from Stanford in 1984 and moved to Bozeman, Montana. Here, he continued his studies of biological clocks, working with the faculty and lecturing at Montana State University – Bozeman.


In 1969 Pittendrigh left Princeton to join the faculty of Stanford where he helped found the program in Human Biology and later became the director of the Hopkins Marine Station. While serving as the director of the Hopkins Marine Station in 1976-1984, Pittendrigh is credited with helping to rebuild Stanford’s century-old marine biology laboratory, bringing in modern molecular biology, ecology and biomechanics, and turning the station into an internationally famous and vigorous one.”


In 1964-65, Pittendrigh co-chaired the National Academy committee on Mars exploration with Joshua Lederberg, to investigate whether life exists on Mars. The project was conducted at Stanford University and Rockefeller Institute, New York, beginning in the summer of 1964 and concluding in October, 1965. During the same period, he received a NASA exobiology grant for his research on “Circadian Rhythms on a biosatellite and on Earth”, which studied how being in orbit can affect circadian rhythms (though it’s not clear what organisms he studied on, and no later publications could be found on this study). Pittendrigh was also involved in the anti-contamination panel in the international Committee on Space Research (COSPAR), which deals with the risk of contaminating Mars with life from earth and thus destroying man’s opportunity to learn whether life developed spontaneously on Mars. In 1966, Pittendrigh co-authored Biology and the Exploration of Mars: Report of a Study, which describes the findings in the exobiology study of 1964-65.


Pittendrigh met Aschoff in 1958 when Aschoff made his first visit to the United States. Pittendrigh studied the eclosion rate of fruit flies, while Aschoff studied the continuous circadian rhythm of birds, mammals, and humans. They reached two different conclusions of the entrainment model with Aschoff supporting a parametric entrainment concept (gradual entrainment throughout the day) and Pittendrigh supported a nonparametric entrainment concept (entrainment is sudden and once a day). Despite opposing views, Aschoff and Pittendrigh remained close friends, and they had a lifelong intense exchange of notes and ideas.Their research was described by Serge Daan as “always in harmony, never in synchrony.”

Beginning in 1958, Pittendrigh developed the concept of the phase response curve or PRC. The PRC allowed chronobiologists to predict how a biological system would be affected by a change in its light schedule. The PRCs, detected almost simultaneously in Pittendrigh’s and Woody Hastings’ labs, served as the basis for the nonparametric entrainment model that was soon after proposed by Pittendrigh. This nonparametric model of entrainment predicted that the difference between an environmental period (T) and an organism’s intrinsic period (τ) is instantaneously corrected every day when light falls at a particular phase (φ) of the cycle where a phase shift (Δφ) equal to this difference is generated. This is reflected through the expression: Δφ(φ)= τ – T.


After the war, Pittendrigh attended Columbia University to study for his Ph.D. under the evolutionary geneticist Theodosius Dobzhansky. When he finished at Columbia in 1947, he joined the faculty at Princeton, as an assistant professor of biology where he began his work concerning circadian rhythms. While at Princeton, he gained his U.S. citizenship in 1950 and served as dean of graduate studies from 1965 to 1969. Pittendrigh also served on a variety of national scientific boards including the Science Advisory Committee to the Administrator of the National Aeronautics and Space Administration (NASA).


Pittendrigh married Margaret “Mikey” Dorothy Eitelbach during the war. Soon after, they moved to Trinidad and lived in the rain forest, where Pittendrigh worked on malaria control as part of the war effort. He returned to the United States in 1945. Margaret and Colin had two children, Robin Rourk, who currently lives in Louisville, Colorado and Colin Jr., who lives in Bozeman. Pittendrigh had a grandson and a granddaughter. Pittendrigh was an avid fly fisherman and outdoorsman, and he and his wife retired to Bozeman, Montana because of their love of the Rocky Mountains.


He obtained his botany degree from the University of Durham (King’s College) in 1940. Assigned to wartime service as a biologist in Trinidad during World War II, he studied malaria transmission by mosquitoes. After the war, he attended Columbia University to study for his Ph.D. He later joined the faculty of Princeton University and started his chronobiology research. He also co-chaired a Mars exploration project at NASA from 1964 to 1966.


Colin Stephenson Pittendrigh (October 13, 1918 – March 19, 1996) was a British-born biologist who spent most of his adult life in the United States. Pittendrigh is regarded as the “father of the biological clock,” and founded the modern field of chronobiology alongside Jürgen Aschoff and Erwin Bünning. He is known for his careful descriptions of the properties of the circadian clock in Drosophila and other species, and providing the first formal models of how circadian rhythms entrain (synchronize) to local light-dark cycles.

Colin Pittendrigh was born in Whitley Bay, on the coast of Northumberland (today Tyne and Wear) on October 13, 1918. He received his first degree in botany in 1940 from University of Durham, now University of Newcastle upon Tyne.
