Trowel and Masonry Tool Collector Resource : History of W.H. Anderson, Detroit, Michigan

W.H. Anderson was a manufacturer and supplier of tools for stonemason's tools, cement tools, and other tools. They were located at 14 and 16 Macomb St., Detroit, Michigan, but no old buildings are in this area now. William Henry Anderson (1837–1914) founded the company in 1870 or 1871, took his 3 sons into the business, and it operated at least to World War II, when Harold Stewart was president. They used the names W.H. Anderson & Son, W.H. Anderson & Sons, and Anderson Tool & Supply Co. Here is a complete catalog of their cement tools from about 1910:

Many of Anderson's stone hammers and chisels can be seen in this circa 1940 catalog; tools for working stone begin on page 35 of the scanned copy: J.M. Waterston Catalog
