In the days around 1900 most of the hills were bare - very few trees. There were more cattle in the area than people. There were several dairies and chicken farms along the hillsides. The main thoroughfare through the area was San Pablo Avenue with businesses from the County Line near Fairmount Avenue (then called Road 4) to Potrero Avenue (then called Stege Junction). None of the roads were paved so there was dust in the summer and in the winter people had to contend with mud. Between Fairmount Avenue and the county line it was almost impossible to get through without boots on.
After the 1906 earthquake and fire in San Francisco the village of Rust started to grow as refugees from San Francisco moved to this side of the Bay to live.
Wilhelm F. Rust born in Hanover, Germany on November 27, 1857 came to California in 1883. He leased property, built a blacksmith shop and his business grew. He later purchased and erected a hardware store. In one corner of his hardware store the first Post Office was opened in 1909 and Rust was named the first Postmaster on March 1, 1909.

People started to refer to the town as Rust and the name stuck until the town of 1500 people was incorporated as a city on 1917. The people did not care for the name of Rust so they changed it to El Cerrito, which means Little Hill in Spanish. Rust has been called the founder of this city and was well liked by the people and praised as an honest, trustworthy citizen and businessman.
