PHOTOGRAPHS: Photographs not associated specifically with other series. Most relate to the dredging, manufacturing and mining activities of the Hammon enterprises.

In 1895, Wendell P. Hammon noted placer gold in the dirt from a well he was drilling near Biggs, Butte County, and became interested in the potential of mining alluvial placer gold deposits with dredges. In partnership with Thomas Couch, he began operating a dredge near the Feather River in 1898. He formed the Yuba Consolidated Gold Fields with eastern capital, and began dredging operations adjacent to Yuba River in 1903. That company maintained a company town, Hammonton, near its dredging operation. Over sixty-five years, this company used twenty-two dredges and obtained 138 million dollars in gold, establishing Hammon's reputation as "The Dredge King". Hammon was also involved in the formation of the Hammonton Consolidated Gold Fields in Alaska and the Natomas Consolidated Company near Folsom.
In addition to dredging operations, the Hammon enterprises engaged in the manufacture of dredges after purchasing the Western Engineering Company and the Boston Machine Shop, and forming the Yuba Construction Company. The later firm evolved into the Yuba Manufacturing Company, a major manufacturer of dredges, which became a subsidiary of Yuba Consolidated Industries, encompassing Hammon's mining ventures. The family also had an interest in the Stockton Iron Works, which manufactured dredges used in reclamation, and other equipment. Wendell P. was also active in citrus growing, packing, electricity, oil and real estate.
These businesses were carried on, in varying degrees, by his son, Wendell C. Hammon, and his grandson, Wendell Hammon. Wendell C. Hammon was primarily associated with the Hammon Engineering Company, a geological and mining engineering firm. He also served as vice president of the Yuba Manufacturing Company. Wendell Hammon was employed in the insurance industry, served in World War II and Korea, and then obtained a degree in history from San Jose State University. In 1975 he established Hammon's Archives and Artifacts in Old Town Sacramento, dealing in books, manuscripts, and ephemera. He was the source of the material in this collection.
