Records of the Macaulay Foundry of Berkeley, California, including administrative materials, financial records, records of the pattern shop, and other assorted materials.

The Macaulay Foundry was founded in San Francisco, California in 1896 by Henry Clayton Macaulay, who had come to California in 1891. During his first five years in California, Macaulay worked as s molder at the National Iron Works and then as foundry foreman for the Byron Jackson Machine Works. In 1896, Byron Jackson, faced with a foundry that was an economic liability during the depression of the 1890s, sold his foundry to Macaulay. The foundry was located on Bluxome Street, in the center of the city's manufacturing district, and it started making castings primarily for Byron Jackson's Machine Shop and soliciting for whatever other business was available. Macaulay's early partners in this venture were John Lauffner, Philip McHale and Daniel Molander. In 1906, the foundry was destroyed in the great earthquake and fire that consumed San Francisco's business and manufacturing districts. H.C. Macaulay, like many other San Francisco manufacturers at the time, decided to move across the bay. The Macaulay Foundry was rebuilt on Carleton Street in Berkeley, California. The company was formally incorporated as the H.C. Macaulay Foundry in 1906. From 1896 until 1937, the Macaulay Foundry's largest customer was the Byron Jackson Machine Works, the largest pump manufacturer in the West. Other prominent early customers included the Hall-Scott Motor Car Company, the Union Gas Engine Company, and the American Can Company. Later customers included Pacific Gas and Electric, Hewlett-Packard, Lawrence Livermore International, and Solar Turbines.
