Content Abstract: The Young Men's Christian Association (YMCA) of San Antonio was created in the spring of 1886 with approximately 100 members. The YMCA of San Antonio was dedicated to putting Judeo-Christian principles into practice while building healthy minds and bodies. Activities included various exercise programs, educational programs and sports leagues, most of which were geared to serve the needs of boys and young men. The bulk of the collection is administrative records, such as the minutes of the Board of Directors, that illustrate the day to day operation of the YMCA of San Antonio. Material concerning the programs at some branches is also included.
