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.

Biography

Wallin was born to

Ammocoete.[5] From 1918, he was professor of anatomy at the University of Colorado Medical School.[3]

Origin of mitochondria

Wallin was the first to experimentally investigate the origin of mitochondria, particularly in relation to their similarities with certain bacteria. His first paper in 1922 described the staining techniques for bacterial cells, and found that the techniques were equally good for staining mitochondria. He concluded that "bacteria and mitochondria have a similar chemical constitution".

chloroplasts are "bacteria or bacteria-like organisms that accepted the leisure of a symbiotic partnership in the struggle for existence". He made a summary conclusion that:[7]

From the evidence that has been recorded in these studies, together with the evidence that may be found in mitochondrial literature, the author can arrive at no other conclusion than, that mitochondria are symbiotic bacteria in the cytoplasm of the cells of all higher organisms whose symbiotic existence had its inception at the dawn of phylogenetic evolution. The conception embodied in this conclusion presupposes that the establishment of new symbiotic complexes is coexistent with the development of new species.

Wallin was aware that he needed to culture mitochondria isolated from cell in an independent environment. His early experiment was a failure using tissue samples from

endosymbiotic theory with better evidences in 1967.[11]

Personal life

Wallin married Eva Louise Shepard.[12]

Wallin was known for his eccentric behaviour in his professional life. He avoided lecturing, but instead used practical demonstrations. He frequently organised parties for his students, who in return helped him build a cabin in

North St. Vrain Canyon, 20 miles north of Boulder. The parties were simply named "Club Wallin" which involved heavy drinking beside playing games. His notable habit was holding an annual Christmas glögg party. At the party guests were treated with Swedish delicacies such as sillsallad (pickled herring salad), lutefisk (dried codfish), and mulled wine.[3]
