Clarence Birdseye marketed the first frozen peas in Chester, N.Y. While a U.S. field naturalist near the Arctic, he had learned the technique of flash freezing from Labrador Inuit. Freshly caught fish, when placed onto the Arctic ice in the frigid wind, froze solid almost immediately. In Sep 1922, he began a company, Birdseye Seafoods, Inc., to process chilled fish fillets at a plant near the Fulton Fish Market in New York City. On 3 Jul 1924, he organized the General Seafood Corporation, which began the frozen foods industry. Retail frozen foods began 6 Mar 1930, in Springfield, Massachusetts at the "Springfield Experiment Test Market" which offered 26 different vegetables, fruits, fish, and meats.
