Donald J. Lisk, M.S. ’54, Ph.D. ’56, professor emeritus of soil chemistry and toxicology and a champion of graduate education, died April 27. He was 88.
A former director of Cornell’s Toxic Chemicals Laboratory, Lisk was known for his work analyzing pesticides – including DDT – in soils, plants and animals; the toxic effects of chemicals on occupationally exposed populations; and the effects of diet on inhibiting cancer.
“Although Don was primarily a researcher, he was committed to graduate students and, upon his retirement, left a substantial amount of unrestricted funds to the Department of Horticulture to support graduate education,” said Marvin Pritts, professor of horticulture. “Don was always willing to take time to learn about what others were doing and share exciting findings from his own work.”
