The city of Fontana, located in San Bernardino County, has a relatively recent but rich history closely tied to the key stages of Southern California's development in the 20th century.
Fontana was founded in 1913 by American entrepreneur Azariel Blanchard Miller. Initially, it was primarily a rural settlement with an economy based on farming, citrus and nut cultivation, and livestock. For a long time, Fontana remained a small agrarian community. The city received a significant developmental boost in 1926 when the famous Route 66 was routed through its territory, fostering growth and improving transport accessibility.
A turning point in Fontana's history occurred in the 1940s. Industrialist Henry John Kaiser chose this location to build the massive Kaiser Steel plant. This decision fundamentally altered the city's economic and social landscape. The plant became one of the most important industrial sites on the U.S. West Coast and attracted thousands of workers, leading to rapid population growth. Its geographic location at the foot of the San Gabriel Mountains and proximity to major transport arteries—such as the I-10, I-15, and the railroad—solidified the city's strategic importance as an industrial and logistics hub.
The post-war period established Fontana's reputation as an industrial city with a working-class population. The economy centered around steel production. However, the closure of the Kaiser Steel plant in the 1980s presented a serious challenge. In the following decades, Fontana began actively diversifying its economy, evolving into a major logistics and distribution hub for Southern California. Today, it hosts large warehouses and distribution centers for many companies. Despite its industrial heritage, the city's cultural life is also flourishing, with new parks and public spaces emerging.
