Leon Springs is on Interstate 10 nineteen miles northwest of downtown San Antonio in northwestern Bexar County. In 1846 it was the site of a stagecoach stop operated by George von Pleve, a German nobleman and immigrant. A post office was established in 1857, and by 1885 the town had a steam cotton gin, a general store, two hotels, and a population of fifty. During World War I Leon Springs was the site of an officers' training camp. The post office was closed in 1918, and by the mid-1930s the population had fallen to twenty-five. The town began to grow again during World War II due to activity at Camp Stanley and Camp Bullis in the nearby Leon Springs Reservation. In 1946 the community had a population of 100. Subsequently, the number of residents remained steady, and in 1990 and 2000 the reported population was 137.
