Cox, born in Austin was put on his first horse at the age of 16 by Buck Steiner. He also rode bareback horses and occasionally rode bulls or entered the steer wrestling for an all around title.
Raised on a ranch, he followed the rodeo trail from 1939 until 1959 but also maintained the ranch for rodeo producer Tommy Steiner and worked for Steiner at the rodeos. His colorful career included stunt-doubling in the bucking horse scene of the famous movie “Giant”.
In 1951, he won nine bronc riding in a row, competing nationwide and also going to Cuba and Australia. He trained racehorses from 1961 to 1966 in Ellenburg, Washington. He eventually came back to his ranch and home in Spicewood. To quote announcer Tom Hadley, ” a guy who’s small in size and large in ability”.
