Warren Gammon
GAMMON, WARREN (1846–1923), inducted 1979
Although he was trained in law, Iowan Warren Gammon focused his energies on cattle breeding and made his mark as the founder of the Polled Hereford breed. While visiting the Trans-Mississippi Exposition in Omaha, 1898, Gammon became intrigued by polled Hereford crossbreeds on exhibit. His college-aged son introduced him to Charles Darwin’s works on heredity, and those writings inspired him to contact the 2,500 breeders on the Hereford registry to locate purebreds exhibiting a hornless mutation. He obtained eleven animals and began breeding in 1902. Warren Gammon established a separate Polled Hereford registry and served as executive secretary of the new breed organization for many years.
