Susan Soltau Kilham, Ph. D.

Age 79 of Haddonfield, NJ

On April 12, 2022; Age 79; of Haddonfield, NJ; Beloved wife of the late Peter Kilham; Cherished Aunt of Jessica Scruggs, Thomas Soltau and Andrew Soltau all of Baton Rouge, LA; Dear Great Aunt of Victoria (Ian) Kenyon, Megan & Rachel Scruggs and Robyn Soltau; Sister of the late Edward and the late Thomas Soltau.

Susan was born in Duluth MN and grew up in Florida where she became fascinated with oceans and the organisms that live in them. She earned a BS in biology at Eckerd College and a Ph.D. in marine science at Duke University. She made many important discoveries about marine and freshwater biology including the calcification of deep-sea clams (1 inch long and 300 years old!), biological processes in African lakes, the importance of resource ratios in the growth and competition of algae in freshwater lakes, the effects of climate change on diatoms in Yellowstone Lake, and systems to grow algae in the laboratory. She was a professor at University of Michigan and Drexel University where she and her students contributed to our understanding of ecological changes related to invasive species, climate change, and the biology of tropical streams. Susan overcame many challenges including sexism to become one of the leading scientists in aquatic biology and ecology. The EPA policy on control of endocrine disruptors in the environment is a direct result of her research in that area. Her students continue her tradition of excellence in science and mentorship.
