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 master 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. While Richardson never fully realized his dream, it was his planning that laid the foundation for what is currently the City of Adelanto. Acre after acre of deciduous fruit trees once grew in the city.
