André Tridon Jagendorf (October 21, 1926 – March 13, 2017) was an American plant biologist and educator. He was a Liberty Hyde Bailey Professor Emeritus in the Section of Plant Biology at Cornell University. He was known for providing direct evidence that chloroplasts synthesize adenosine triphosphate (ATP) using the chemiosmotic mechanism proposed by Peter Mitchell.
Jagendorf was born in New York City on October 21, 1926. He studied at Cornell University, at Yale University and at the University of California, Los Angeles. Jagendorf died in Ithaca, New York from a heart attack on March 13, 2017, aged 90.
