William Rosenberg (June 10, 1916 – September 22, 2002) was an American entrepreneur who founded the Dunkin’ Donuts franchise in 1950 in Quincy, Massachusetts, one of the pioneers in name-brand franchising, originally named the “Open Kettle” doughnut shop when established in 1948. At the end of 2011, there were more than 10,000 outlets of the chain in 32 countries.

Life and career

Rosenberg was born in Boston, Massachusetts one of four children of Nathan Rosenberg, a grocery owner, and Phoebe Rosenberg née Swart, Jewish immigrants from Eastern Europe. Rosenberg grew up in Boston’s working-class Dorchester section and was educated in public schools. Due to financial problems, he was forced to leave school by eighth grade to help support his family, who had lost their store in the Great Depression. After several different jobs, at age fourteen, he went to work for Western Union as a full-time telegram delivery boy. At seventeen, he started working for Simco, a company that distributed ice cream from refrigerated trucks, rising from delivery boy to national sales manager at age twenty-one, supervising the production, shipping, cold storage and manufacturing and managing 40 to 100 trucks.

At the start of World War II, he joined the Bethlehem Steel Company in Hingham, Massachusetts. He would later become the first Jewish Trade union delegate. After the war, Rosenberg borrowed $1,000 to add to his $1,500 in war bonds and used his knowledge of food distribution to open his first company “Industrial Luncheon Services”, a company that delivered meals and coffee break snacks to factory workers on the outskirts of Boston, Massachusetts. Rosenberg created his own catering vehicles, with sides that rose to reveal sandwiches and snacks stocked on stainless steel shelves, a prototype for today’s mobile catering vans. Within a short time, he had 200 catering trucks, 25 in-plant outlets and a vending operation. Noticing that forty percent of his revenues came from coffee and doughnuts, he started a retail shop that specialized in those products, opening his first coffee and doughnut shop, the “Open Kettle” on Memorial Day in 1948, later renamed “Dunkin’ Donuts”. Instead of the five different types of doughnuts doughnut shops traditionally offered, Rosenberg offered 52 different varieties. In 1955, upon opening his sixth shop, he decided on the concept of franchising his business as a means of distribution and expansion. In 1959, after the franchise idea had started to catch on, he lobbied at a trade show for the creation of the industry group that became the International Franchise Association in 1960.

In 1968, Rosenberg bought Wilrose Farm in New Hampshire. After being diagnosed with lung cancer in 1971, he devoted his time mainly to Wilrose Farm, becoming the largest standardbred breeder in New England and was inducted into the New England Hall of Fame of the Standardbred Industry. In 1980, he donated Wilrose Farm to the University of New Hampshire.

In 2001, he published his autobiography, Time to Make the Donuts: The Founder of Dunkin Donuts Shares an American Journey, written with the help of Jessica Brilliant Keener.
