Roots in Herberts Machinery and Supply
MASCO's story starts before the company itself. Herberts Machinery and Supply Co. is formed in Los Angeles as a machine tool distributorship by C. A. Herberts, and incorporated as a California corporation in 1917.
1938
Machinery Sales Co. founded
Three officers of the Herberts company, D. N. Macconel, Nathan Troop, and S. W. Clawson, acquire its assets on March 14, 1938 and form Machinery Sales Company, with Macconel as first president. The new company takes over the Herberts sales force and lines, selling from a first office on Santa Fe Avenue in Vernon.
1948
A building of its own
After outgrowing its first offices, the company opens its own new building at 2838 Leonis Boulevard in Vernon.
1953
Fire, and a two-day recovery
A disastrous fire razes the Leonis Boulevard building to the ground, destroying everything but the company records. MASCO is operating as usual within two days, and new facilities rise on the same site.
1960
Howard Christanson becomes president
Christanson, with the company since 1941, becomes president following the death of D. N. Macconel. The same year, Kimball Smith joins as vice president of sales after 18 years in the Los Angeles machine tool trade. Smith goes on to lead MASCO's growth for nearly four decades, eventually taking ownership of the company, until his retirement in the late 1990s.
