The company was founded by Alanson Partridge Brush (February 10, 1878, Michigan – March 6, 1952, Michigan).
He was a self-taught prolific designer, working with Henry Leland at Oldsmobile, and went on to helped design the original one-cylinder Cadillac engine.
Although there were many makes of small runabouts of similar size and one to four cylinders at this time (before the Model T Ford dominated the low-price market), the Brush has many unusual design details showing the inventiveness of its creator.
The Brush Runabout Company, along with Maxwell-Briscoe, Stoddard-Dayton, and others formed Benjamin Briscoe's United States Motor Company(USMC) from 1910, ending when that company failed in 1913.
Runabouts, in general, fell out of vogue quickly, partly due to the lack of protection from the weather.

After Brush and the other companies of the USMC folded into Maxwell Motor Company, President Walter Flanders wrote in 1913 document "Why We Did Not Use All Our Plants", the Brush factory in Detroit (along with the Flanders and Sampson  Plants) were to remain open and running as factories.
