Albert Powers Halfhill (November 25, 1847 – May 7, 1924) was an American groceryman and a food manufacturer. He originated the idea of removing the natural fish oil from tuna and substituting it with a vegetable oil and then cooking it with compressed hot steam to produce a desirable food. He labeled his uniquely prepared cooked fish "chicken of the sea" and it became a popular American food in the early twentieth century. Halfhill is known as the father of the tuna packing industry.
