By 1954, as an assistant professor with a group of three graduate students, I was able to initiate more complex experimental projects, dealing with the structure, stereochemistry and synthesis of natural products. As a result of the success of this research, I was appointed in 1956, at age twenty-seven, as professor of chemistry.
My doctoral work was completed by the end of 1950 and, at the age of twenty-two, I joined the University of Illinois at Urbana-Champaign as an instructor in chemistry under the distinguished chemists Roger Adams and Carl S. Marvel.
