Robert Rosenberg served as chief executive officer of Dunkin' Donuts from 1963 until his retirement in 1998. Under his leadership, the company grew from a regional family business to one of America's best known and loved brands. Rosenberg received his MBA from Harvard Business School, and in just weeks after graduating at the age of 25, assumed the position of chief executive officer. Dunkin' Donuts was a publicly owned company from 1968 until 1989 and earned a reputation for extraordinary stockholder returns. In that 21-year period, it earned its investors a 35 percent compound rate of return. After retiring from Dunkin, Rosenberg taught in the Graduate School at Babson College and served many years on the boards of directors of other leading food service companies, including Domino's Pizza and Sonic Restaurants.
