Weed scientist Russell Hahn dies at 81

Russell R. Hahn, a leader among weed scientists and fondly known as the "weed warrior" across upstate New York, died Dec. 2, 2024, in Sayre, Pennsylvania. He was 81.

Born Sept. 19, 1943, in Sutherland, Nebraska, Hahn grew up on the family farm southwest of Paxton, Nebraska, where his early experiences would shape his lifelong dedication to agriculture. Hahn received his B.S. and M.S. degrees in agronomy and weed science from the University of Nebraska, Lincoln, in 1964 and 1968 respectively. He later received his Ph.D. in weed science from Texas A&M University in 1974 and joined the faculty of the College of Agriculture and Life Sciences (CALS) in March of that year.
