Chancey Juday (1871-1944) 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.[1][2] 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.

Juday, born in 1871 at Millersburg, Indiana, completed his A.B. (1896) and A.M. (1897) degrees at Indiana University. Many years later he was also awarded an honorary LL.D.

Juday was one of the founders of the Limnological Society of America, serving as its president for two years. He was awarded the Leidy Medal (1943) by the Philadelphia Academy of Natural Sciences, and in 1950 shared posthumously the Einar Naumann Medal of the International Association of Limnology with Birge.[2][3]

Juday was hired by Birge, and they studied Lake Mendota in Madison, Wisconsin. Their findings involving dissolved oxygen and temperature lead future limnologists to important information regarding stratification in lakes.
