Beginning in the early 1930s, Tom Lasater, the breed's founder, developed Beefmasters from a systematic crossing of Hereford, Shorthorn and Brahman cattle. His purpose was to develop cattle that were more productive than existing breeds; cattle that would produce and make money during economically hard times in the harsh environment of South Texas. The new breed was developed on what has become known as the Six Essentials - Weight, Conformation, Milk Production, Fertility, Hardiness and Disposition. These essentials became the economic strength of Beefmasters and have made them favorites with those who depend on cattle for a living. Beefmasters are the only beef breed specifically developed to excel in these important economic traits.
