Historical Note

Rancho San Luis Rey was one of the most prominent horse-breeding ranches in the Southwestern United States during the 1930s and 1940s. Owned and operated by Charles E. Cooper, the ranch bred, sold, and ran horses throughout California and Tijuana. Cooper was an integral part of the early development of North San Diego County (Bonsal), the Del Mar Race Track, horse racing in California, and Wilshire Boulevard.
