Eli Lilly (April 1, 1885 – January 24, 1977), sometimes referred to as Eli Lilly Jr. to distinguish him from his grandfather of the same name, was an American pharmaceutical industrialist and philanthropist from Indianapolis, Indiana, United States. During his tenure as head of Eli Lilly and Company, which was founded by his grandfather, the company grew from a successful, family-owned business into a modern corporation and industry leader. Lilly served as the company president (1932–1948), chairman of the board of directors (1948–1961 and 1966–1969), and honorary chairman of the board (1961–1966 and 1969–1977).
