David Starr Jordan (1851-1931) Ichthyology, Evolutionary Biology - Indiana University, Stanford University
A leading American ichthyologist, Jordan catalogued North America's fish species and explored evolutionary principles despite heavy controversy surrounding the idea at the time. He was also a highly influential educator and served as President of Indiana University at the age of 34 and became the founding President of Stanford University at 40. Though one of the foremost ichthyologists of his time, Jordan left a controversial legacy.
Chancey Juday (1871-1944) Limnology – University of Wisconsin, Madison
Working with Edward Birge, Juday pioneered the field of limnology, the study of lakes, and taught the first graduate students of limnology in North America. His work became the foundation for the Center for Limnology. He also served as President of the Ecological Society of America in 1927.
Arthur D. Hasler (1908-2001) Limnology, Ecology - University of Wisconsin, Madison
Hasler took up the reins of his limnology forbearers, directed the future of the science with a strong emphasis on large scale manipulations known as whole-lake experiments. He is best known for his discovery that salmon used olfactory imprinting to facilitate their returns to precise locations of birth for spawning. He was also a pioneer in the study of eutrophication. He advised 95 graduate students, was the third ecologist (after G.E. Hutchinson, and C. L. Hubbs) to become a NAS member, and was later elected to the AAAS.
Kenneth B. Armitage (1925-2022) Behavioral Ecology - University of Kansas
Ken Armitage started academic life as limnologist, but became interested in social behavior of mammals, and spent much of his 40-year career studying this in yellow-bellied marmots. His most recent book, Marmot Biology, is a thorough treatment of marmot ecology covering published research over the last fifty years, including his own forty year study at the Rocky Mountain Biological Laboratory. He devoted much of his time toward educating the next generation and supervised over 40 graduate students at the University of Kansas.
