The original Peacock Military Academy was founded in 1894 in San Antonio by Wesley Peacock, a well-known educator and child psychologist. In 1930 Peacock opened a north Texas branch of the school at this site to provide military, academic, and physical education for young men in the first grade through junior college. Although the Dallas branch of the Peacock Military Academy went bankrupt and closed in 1934, its central administration building has been used as an educational facility since 1938.
