Robert L. McNeil, Jr. begins his interview by discussing his parent's heritage and the evolution of the Firm of Robert McNeil, the drugstore started by his grandfather. As young men, McNeil and his brother worked as errand boys for their father. During the summers, McNeil traveled, working on a ranch and as a camp counselor. McNeil attended high school at Germantown Academy, and went to Yale University to study physiological chemistry and bacteriology. After receiving his B.S. degree, he returned to Philadelphia. Subsequent to his grandfather's death, McNeil, at the young age of twenty, began his career in the family business, which by then had evolved into McNeil Laboratories, Inc., headed by his father, R. Lincoln McNeil. By attending pharmaceutical conferences as well as enrolling in the Philadelphia College of Pharmacy's four-year program and Temple University's Graduate Pharmacy School course in pharmacology, under Professor James Munch, McNeil was able to gain the experience necessary to eventually head a successful pharmaceutical company. One of McNeil's first challenges was helping McNeil Laboratories update their manufacturing practices in keeping with the new Federal Food, Drug and Cosmetic Act of 1938. With his strong knowledge of pharmacology, and the advice of many of the top men in Philadelphia's medical field, McNeil was able to introduce what would become some of the top-selling pharmaceuticals in the nation, including Butisol® and eventually Tylenol®. While helping McNeil Laboratories to reach a new level of success, McNeil was on the board of many pharmaceutical organizations, and was the president of the Philadelphia Drug Exchange, as well as the Philadelphia branch of the American Pharmaceutical Association. McNeil also found time to marry and to help raise three children, along with a stepson from his wife's previous marriage. In 1959, McNeil Laboratories was sold to Johnson & Johnson and after a seven-year "transitional" period, McNeil retired and entered the venture capital field. He also devoted time to the study of our Colonial history and material culture and to the development of The Barra Foundation (originally named The Robert L. McNeil, Jr. Foundation). McNeil concludes his interview with a short comment on his views of the fast evolution of today's pharmaceutical field
