Robert 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% compound rate of return and won accolades from Peter Lynch, famed Fidelity fund manager, who referred to Dunkin’ Donuts as one of his greatest “ten baggers.”
In 1990, Dunkin’ Donuts was purchased by Allied Domecq PLC, a large UK diversified food and beverage company. Rosenberg remained with Allied Domecq for nearly nine years, continuing his leadership of Dunkin’ Donuts, as well as assuming responsibility for Baskin Robbins, a subsidiary of Allied Domecq since the 1970s.
Upon his retirement, Rosenberg had grown the Dunkin’ Donuts chain to over 4,000 stores worldwide with annual system-wide sales in excess of $2 billion.
