Chancey Juday together with G. Evelyn Hutchinson, and his close collaborator, Edward A. Birge were pioneers of North American limnology. Birge and Juday founded an influential school of limnology on Lake Mendota at the University of Wisconsin. Edward Birge hired Chancey Juday through this program to help him take samples of lakes in Wisconsin. Their main sampling took place on Lake Mendota. The two, Juday and Birge, studied dissolved oxygen and temperature, leading future limnologists to a better understanding of stratification.
