Technical Supply Company sold drawing materials in Scranton, Pa., by 1903. This set does not resemble any of the sets in the firm's 1912 catalog. Compare to 1989.0305.05. For other sets with Schoenner instruments, see 1977.0279.01, 1977.1101.0097, 1979.0868.01, 1990.0350.01, 1990.0690.01, and MA*317925.04.
Dr. Robert P. Multhauf (1919–2004), who owned this set, graduated from Iowa State College in 1941, served in the U.S. Navy from 1943 to 1947, and earned a Ph.D. from the University of California at Berkeley in 1953. He joined the Smithsonian in 1954 and directed the Museum of History and Technology (later the National Museum of American History) from 1966 to 1969. After serving in other positions, he retired from the Smithsonian in 1987. He likely purchased this set early in his career.
