In 1850, Morris Greenberg left Paris, France, accompanied by his wife and two children; they reached California in 1851. In 1854, he established the "M. Greenberg, Eagle Brass Foundry," at 58 Halleck St., in San Francisco. In the 1850s and 1860s, the firm produced bronze spikes for wooden ships and horse-collar pipes and nozzles for hydraulic mining. The firm also invented the California-type fire hydrant that maintained constant pressure and was more reliable than the type used in the East.
Contains three photographs (circa 1890-1910) of or relating to M. Greenberg's Sons, Brass Foundry and Machine Works, including a line of workers and three cars in front of a building that was owned by the firm and which had the firm's logo on it; an unknown individual who might be Morris Greenberg; and eight of the company's workers. The collection also includes a program prepared for the company's 100th anniversary (1954).
