The C. R. Patterson and Sons Company conducted business in Greenfield, Ohio, from 1865-1939. Founded by Charles Richard (C.R.) Patterson, a free person of color born in the 1830s South and relocating to the North in the 1840s, this company passed through three generations of the Patterson family. Throughout its history the company transitioned from building carriages, automobiles, trucks, and then buses, all in order to keep up with the rapidly changing demands and technology of the transportation industry during that period. When C. R.’s son, Frederick, began producing automobiles in 1915, he became the first and only Black manufacturer known to have built an automobile. This company led many pioneering efforts in providing proper vehicles for both horse-drawn and motorized school transportation and was also an industry leader in winter buggy design. The company nearly saturated the markets of Ohio and surrounding states with their school buses during the 1920s.
