Arthur Harold Beal is known as Der Tinkerpaw or Captain Nitt Witt. Beal was garbage collector for the town of Cambria in the 1940s and '50s, and made good use of what Cambrians were throwing away, as well as the natural materials on the property, in the nearby pine forests, and on the area's beaches. Some parts are also reportedly remnants from Hearst Castle where he reportedly worked for a time. Other common building materials are beer cans, abalone shells, and concrete. There are also washer drums, car rims, tile, car parts, and old stoves.
