In 1900 Dorrance became vice president of the Joseph Cambell Preserve Company. At the Exposition Universelle in Paris that year, Campbell's soups won a gold medal. The medal is still shown on the soup cans today. Dorrance found that workers had time on their hands watching the soup cook in the factory. To occupy their time Dorrance created a new product: canned pork and beans. In 1914 Dorrance became president of the company, now called the Campbell Soup Company. He died of a heart disease on September 22, 1930 in Camden, New Jersey.
