Charles W. Gehrke (18 July 1917 in New York City, New York – 10 February 2009 in Columbia, Missouri) was an American chemist, researcher and business entrepreneur. Biography and career Gehrke was born in New York City to a German immigrant mother (Louise Mader Gehrke) and a laborer father (Heinrich Gehrke). The family moved to Ohio when Charles was young. His father suffered from alcohol abuse, and when Charles was 10 years old, local police put the father on a train and told him that he would face jail for physically abusing his family if he ever returned. Left with five small children, the mother took cleaning jobs in the nearby town (Coshocton), and the two older boys (Hank, born 1916 and Charles) worked as much as possible as field hands, often taking care of their infant brother as they worked. Gehrke received a B.A. degree (1939), a B.S. degree in Education (1941) and an M.S. degree in Bacteriology (1941) from Ohio State University. Gehrke served as professor of Chemistry and "chairman of the Chemistry Department" (he provided the title to a biographer in 2008, then explained that he was the only member of the department) at Missouri Valley College, whose students were largely junior officers in the United States Navy (1941–1945). When World War II wound down he returned to OSU, instructing in Agricultural Biochemistry and working on a Ph.D. He received the degree in 1947. He joined the University of Missouri's Agriculture Department (1949) and remained there until retiring (1987). At his retirement he held the titles "Professor of Biochemistry", "manager of the Experiment Station Chemical Laboratories", and "director of University Interdisciplinary Chromatography-Mass Spectrometry facility." After retiring, Gehrke served as scientific coordinator for the Cancer Research Center in Columbia (1987-1989). While still at MU Gehrke co-founded (with David Stalling and Jim Ussary) a company devoted to development and manufacture of chromatography instruments, Analytical Bio-Chemistry Laboratories Inc. (ABC Labs) based in Columbia, Missouri. In 2015, ABC Labs was bought out by EAG Laboratories, and in 2017, the firm was purchased by Eurofins. The company presently provides pharmaceutical and environmental services, and employs more than 300 people. Gehrke met future wife Virginia Horcher at OSU. They married Christmas Day (25 December) 1941 at Zanesville, Ohio, and she died on their anniversary day 65 years later (2006). They had three children, two of whom survived their parents. Gehrke published 270 peer-reviewed
