Duncan Hines was an American pioneer of restaurant ratings for travelers. He is best known today for the brand of food products that bears his name. Hines was a travelling salesman and by the age of 55, Hines and his wife Florence began assembling a list for friends of several hundred good restaurants around the country. The list became popular and he began selling the paperback book Adventures in Good Eating (1935), highlighting restaurants and their featured dishes that Hines had personally enjoyed in locations across America. Duncan Hines introduced his first baked goods in 1952, at the age of 72. In 1957, the range was expanded by Procter & Gamble and the company expanded the business to the national market and added a series of related products.
