Dreyer’s Grand Ice Cream Holdings, Inc. (“Dreyers”), is an American ice cream company, founded in 1928 in Oakland, California, where its present-day headquarters office remains. The company’s two signature brands, Dreyer’s Grand Ice Cream and Edy’s Grand Ice Cream, are named after its founders, William Dreyer and Joseph Edy. The Dreyer’s brand is sold in the Western United States and Texas, while the Edy’s brand is sold in the Eastern and Midwestern United States.

In 1928 Edy and Dreyer decided to join forces to manufacture ice cream. They secured a small factory and launched Edy’s Grand Ice Cream (the “Grand” reflected their street address on Grand Avenue in Oakland). They focused on creative innovations to fuel their small venture. For example, the two men used Joseph Edy’s knowledge and expertise in candy-making to create the original Rocky Road ice cream, from a combination of flavors which Edy had previously invented. The chocolate, marshmallow, and nut flavor was named Rocky Road as a means of describing the ice cream’s texture as well as the troubled economic times of the Great Depression. Edy and Dreyer are also credited with originating the Toasted Almond and Candy Mint flavors. At the time ice cream had limited flavors such as vanilla, chocolate, and strawberry, but Rocky Road, introduced in 1929, was one of the first combination of flavors. Because only large marshmallows were manufactured at the time, he used his wife’s sewing scissors to cut marshmallows into bite-sized pieces to make the first batch of Rocky Road.
