English: Looking south at the Michigan Building, also known as the Lovelace Building (20 West Main), in Bozeman, Montana. E. Broox Martin (1844-1921) was raised in Michigan, and when a fire destroyed his milling operation there he relocated to Bozeman -- where he started the famous Bozeman Milling Company. He got fabulously wealthy, bought a hotel in nearby Manhattan, then raised barley on a 320-acre farm in the Gallatin Valley, and founded the Commercial Exchange Bank. He built this three-story building -- then highly unusual for Bozeman (it still is) -- in 1905, and named it after his native state. The building was designed by Fred Willson. The east side of the ground floor was occupied by 1910 by the Bungalow Ice Cream Parlor -- which advertised itself as the "Largest Ice Cream Parlor in the West!" It became a Bozeman legend (but closed in 1994).

John Lovelace, the owner of Montana Motor Supply (a local motor parts company), bought the structure in 1934. He hired Willson to cover over the building's brick and iron facade, and add a new Art Deco surface. Lovelace moved Montana Motor Supply into the west ground floor space.

By 1945, Lovelace had purchased the building across the street -- and renamed it the Hathhorn Building after his wife, Montana Lilly Hathhorn.

A major renovation of the Lovelace Building in 2005 restored the original facade. Special dark green glass in the windows mimics that originally used in 1905. The upper floors are now apartments.
