Leslie Salt
Leslie Salt Company was a salt producer in the San Francisco Bay Area, using evaporation ponds along the bay near Newark, Hayward, and other parts of the area. It had been in business since 1901 and became part of Cargill Inc. in 1978. The name was shortened to Leslie Salt in 1936 after California Salt Co. and Continental Salt & Chemical Co. merged. Under the Schilling family, it became the Bay Area’s largest private landowner by the 1940s, and by 1959 it produced more than a million tons of salt each year on about 26,000 acres of ponds. Cargill bought Leslie Salt in 1978 and kept using the Leslie name until 1991.
