Clarence Birdseye was the sixth of nine children of Clarence Frank Birdseye, a lawyer in an insurance firm, and Ada Jane Underwood. His first years were spent in Brooklyn, New York, where his family owned a comfortable townhouse in Cobble Hill. From childhood, Birdseye was obsessed with natural science and with Taxidermy, which he taught himself by correspondence.
Conventional freezing methods of the time were commonly done at higher temperatures, and thus the freezing occurred much more slowly, giving ice crystals more time to grow. It is now known that fast freezing produces smaller ice crystals, which cause less damage to the tissue structure. When 'slow' frozen foods thaw, cellular fluids leak from the ice crystal-damaged tissue, giving the resulting food a mushy or dry consistency upon preparation. Birdseye solved this problem.
In 1922, Birdseye conducted fish-freezing experiments at the Clothel Refrigerating Company, and then established his own company, Birdseye Seafoods Inc., to freeze fish fillets with chilled air at -43 °C (-45 °F). In 1924, his company went bankrupt for lack of consumer interest in the product. That same year he developed an entirely new process for commercially viable quick-freezing: packing fish in cartons, then freezing the contents between two refrigerated surfaces under pressure. Birdseye created a new company, General Seafood Corporation, to promote this method.
In 1925, his General Seafood Corporation moved to Gloucester, Massachusetts. There it employed Birdseye's newest invention, the double belt freezer, in which cold brine chilled a pair of stainless steel belts carrying packaged fish, freezing the fish quickly. His invention was subsequently issued as US Patent #1,773,079, marking the beginning of today's frozen foods industry. Birdseye took out patents on other machinery, which cooled even more quickly, so that only small ice crystals could form and cell membranes were not damaged. In 1927, he began to extend the process beyond fish to quick-freezing of meat, poultry, fruit, and vegetables.
In 1929, Birdseye sold his company and patents for $22 million to Goldman Sachs and the Postum Company, which eventually became General Foods Corporation, and which founded the Birds Eye Frozen Food Company. Birdseye continued to work with the company, further developing frozen food technology. In 1930, the company began sales experiments in 18 retail stores around Springfield, Massachusetts, to test consumer acceptance of quick-frozen foods. The initial product line featured 26 items, including 18 cuts of frozen meat, spinach and peas, a variety of fruits and berries, blue point oysters, and fish fillets. Consumers liked the new products and today this is considered the birth of retail frozen foods. The "Birds Eye" name remains a leading frozen-food brand. Birdseye was inducted into the National Inventors Hall of Fame in 2005.
