Marc Loudon received his BS (magna cum laude) in chemistry in 1964 from Louisiana State University and his PhD in organic chemistry in 1968 from the University of California, Berkeley, where he worked with Professor Donald S. Noyce. After two years of postdoctoral study with Professor Daniel E. Koshland in the Biochemistry Department at Berkeley, Dr. Loudon joined the chemistry faculty at Cornell University, where he taught organic chemistry to both pre-professional students and science majors. He received the Clark Teaching Prize of Cornell's College of Arts and Sciences in 1976. Since 1977, Dr. Loudon has been Professor of Medicinal Chemistry at Purdue University. Dr. Loudon teaches organic chemistry to pharmacy and pre-pharmacy students at Purdue, where he has twice won the School of Pharmacy's Henry Heine Outstanding Teacher Award. In 1988, he received the Class of 1922 Helping Students Learn Award. In 1996, Dr. Loudon was among three faculty at Purdue who were the first to be named Distinguished Professor on the basis of teaching and teaching scholarship; as result of that award, Dr. Loudon became the Gustav Cwalina Distinguished Professor of Medicinal Chemistry. In 1999, Dr. Loudon won Purdue's university-wide Charles B. Murphy Award for undergraduate teaching and, in the same year, was listed in Purdue's permanent "Book of Great Teachers." In 2000, Dr. Loudon was named "Indiana Professor of the Year" by the Carnegie Foundation. In 2001, Dr. Loudon served as a member of the Chemistry Panel of BIO2010, which was commissioned by the National Academy of Sciences to make national recommendations for the biology curriculum.
