Adelanto is a city in San Bernardino County, California about 9 miles (14 km) northwest of Victorville in the High Desert portion of the Inland Empire of the Greater Los Angeles Area. The name Adelanto means progress oradvance in Spanish, and was first given to the post office that was established on the site in 1917. The population was 31,765 at the 2010 census, up from 18,130 at the 2000 census.
Adelanto was founded in 1915 by E. H. Richardson, the inventor of what became the Hotpoint Electric Iron. He sold his patent and purchased land for $75,000. He had planned to develop one of the first planned communities in Southern California. Richardson subdivided his land into one-acre plots, which he hoped to sell to veterans with respiratory ailments suffered during World War I. He also hoped to build a respiratory hospital. Richardson never fully realized his dream, but his planning laid the foundation for what is currently the City of Adelanto.
Acres of deciduous fruit trees once grew in the city, which became known in the state for its fresh fruit and cider. The orchards thrived until the Great Depression, when they were replaced by poultry ranches. As the wartime emergency developed early in 1941, the Victorville Army Air Field was established with land within the Adelanto sphere of influence. In September 1950, the air field was named George Air Force Base in honor of the late Brigadier General Harold H. George.
Adelanto continued as a "community services district" until 1970, when the city incorporated, and Adelanto became San Bernardino County's smallest city. The city became a charter city in November 1992.
Adelanto has its own school district, the Adelanto School District. It has twelve elementary schools. Students who attend these elementary schools may attend Adelanto High School, or one of two other high schools outside the area in Victorville or Phelan. opened. There is one charter school in town, Adelanto Charter Academy.
