Ivan Emanuel Wallin (22 January 1883 – 6 March 1969)[1] was an American biologist who made the first experimental works on endosymbiotic theory.[2] Nicknamed the "Mitochondria Man", he claimed that mitochondria, which are cell organelles, were once independent bacteria, as supported by his comparative studies and culture of isolated mitochondria.[3] From 1922, he published a series of papers titled "On the nature of mitochondria" in the American Journal of Anatomy which became the experimental foundations of his claims. He was the first person to specifically postulate that eukaryotic organelles originated from bacteria, and that symbiosis is a major force in creation of new species.[4]
Wallin was Professor of Anatomy at the University of Colorado Medical School. He was noted for his eccentric life in academia, such as his preference for exclusively practical demonstration rather than lecturing, his frequent parties for students and an annual Christmas glögg party.
