Vladimir Haensel begins this interview by discussing his family life. Haensel, though born in Germany, spent parts of his childhood in Russia, Austria, and Germany. He attended a German gymnasium, where he had only a few science courses. However, family friends encouraged his burgeoning interest in chemistry. When his father was offered a faculty position at Northwestern University, Haensel's family moved to the United States. Haensel studied engineering at Northwestern, receiving his B.S. in 1935. He earned a scholarship for graduate school at MIT, where he studied polymerization under Edwin R. Gilliland. With the help of a family friend, Vladimir Ipatieff, Haensel was offered a summer position at Universal Oil Products (UOP). After earning his M.S. in chemical engineering in 1937, Haensel took a permanent position at UOP, and helped Ipatieff to set up a high-pressure laboratory (funded by UOP) at Northwestern. During this time, Haensel also earned his Ph.D. in chemistry from Northwestern, writing a thesis on the decomposition of cyclohexane. In the 1940s and 1950s, Haensel moved into research management. He was also integral in UOP's development of the Platforming process. Haensel concludes this interview with a discussion of the importance of instinct in research, the future of research and development, and his thoughts on winning the Perkin Medal.
