The Fess System company, founded in San Francisco, existed from 1907 to 1920. Its name came from Milton A. Fesler (1874-1935), who patented the modern oil burner in 1902. The company reorganized in 1920 as the Petroleum Heat & Power Company, which moved east and went on to become the largest heating oil company in the United States. Fesler lived in Oakland for a time, at 5975 Claremont Avenue.

There is also a cover that says “Oakland Gaslight Company” in front of 1142, built in 1910. Modern houses!
