Chalmer Kirkbride begins the interview by describing his family background and childhood in Oklahoma and Kansas. During high school, Kirkbride's interests were influenced by his brother-in-law, a chemist for Sherwin-Williams. Kirkbride studied chemical engineering at the University of Michigan and spent summers working in the oil fields. He was recruited on campus by Standard Oil of Indiana and worked at the Whiting refinery. Kirkbride also worked for the Pan American Transport Company and Magnolia Petroleum Corporation before being appointed as the first distinguished engineering professor at Texas A&M University. In 1947, Kirkbride returned to industry when he was recruited by the Houdry Process Corporation. He became president of Houdry before moving to Sun Oil Company, where he created a commercial development department and began taking an active interest in environmental issues. After his retirement Kirkbride became president of the Cecil County Anti-Pollution league, founded Kirkbride Associates, and participated in board activities at Widener University.
