Percy S. Truesdell

Died 9 Jul 1948 (born c. 1882).American chemist and manufacturer who was known as the “gumdrop king.” He founded the P.S. Truesdell Candy Manufacturing Company, and was credited with developing the soft, chewy form of the gumdrop. In its earliest form, the gumdrop had been tough. After years of experimenting at Ohio State University's chemistry department, Truesdell found that by reducing the starch content, he could make a gumdrop with a more appealing texture. In 1915, he began producing the gumdrops in the loft of a building in Columbus, Ohio, and travelled around the state marketing it.[Year of birth estimated from obituary notice stating he died at age 66.]
