Abstract of Interview

George Rosenkranz begins the interview with a discussion of his childhood years in Budapest, Hungary. After graduation from the German School, Rosenkranz attended the renowned Swiss Federal Institute of Technology. There, he received his BS in chemical engineering in 1938 and his PhD in 1939. Rosenkranz studied under several luminaries in chemistry, most notably, Leopold Ruzicka. After receiving his PhD, Rosenkranz worked as a research assistant in Leopold Ruzicka’s lab, where he headed a group researching triterpenes. In 1941, Rosenkranz had agreed to teach organic chemistry at the University of Quito, leaving in October 1941 to make the long trip to Ecuador. His three-week-long boat trip eventually stalled in Cuba. While waiting for the boat to Ecuador, Rosenkranz decided to remain in Havana. There he also met his future wife, Edith Stein. Rosenkranz soon landed a position as Director of Research at the Vieta Plasencia Lab. In 1945, Rosenkranz joined Syntex Corporation in Mexico as Scientific Director. His immediate work was on progesterone synthesis. Rosenkranz hired several up-and-coming scientists to work at Syntex, including Carl Djerassi and Alejandro Zaffaroni. Syntex’s major successes were the synthesis of cortisone and Djerassi’s synthesis of oral contraceptives, thus turning a little-known company into a major pharmaceutical powerhouse. In 1982, Rosenkranz retired as chairman of the board, president, and CEO of Syntex. Rosenkranz concludes the interview with a discussion of Syntex’s growth, and thoughts on his family and future endeavors.
