From the 1950s-1970s, Benjamin McAdoo (1920-1981) was the first Black person to own an architecture firm in Seattle and was the first Black man to practice architecture in Washington State. Born in Pasadena, California, he earned a BA at the University of Washington in 1946. He was President of the Seattle Chapter of the NAACP from 1964-1968 during which he broadcast a weekly radio show covering social issues. During his career, McAdoo designed churches, family homes (including his own residence in Bothell), and commercial buildings, exhibiting a style of modernism and regionalism. He worked with the University of Washington, the King County Central Blood Bank, Seattle First National Bank, and the City of Seattle. McAdoo purchased this toolbox when he attended junior college in California.
