title: Buick
context: David Buick incorporated his company as the Buick Motor Company on May 19, 1903, in Detroit, Michigan. Buick had been financed by friend and fellow automobile enthusiast, Benjamin Briscoe, who sold control of the business to James H. Whiting (1842–1919), in September, 1903.[5] of Flint Wagon Works, in Flint, Michigan. Whiting moved Buick to Flint that summer, to a location across the street from his factory, with the idea of adding Buick's engines to his wagons.[2] David Buick stayed on as a manager, and re-hired Walter Marr as chief engineer. The engine Buick and Marr developed for this automobile was a two-cylinder valve-in-head engine of 159 cubic inches, with each cylinder horizontal and opposed to the other by 180 degrees. Whiting built only a few automobiles in 1904, by bringing Buick engines across the street where his workers shoehorned them into his wagons, before running out of capital, causing him to bring in William C. Durant that year as controlling investor. Durant spent the next four years turning Buick into the biggest-selling automobile brand in the US. Durant was co-owner, also in Flint, with Josiah Dallas Dort, of the Durant-Dort Carriage Company, which was the largest carriage-making company in the country and one of the largest in the world.[2] Durant moved most production to the former Durant-Dort Imperial Wheel plant in Jackson, Michigan in 1905. Buick continued car production in Jackson through 1907, when Factory #1 was completed in Flint. The Jackson plant continued production with Buick trucks through 1912.[6] David Buick sold his stock upon departure in 1906, and died in modest circumstances 25 years later. In 1907, Durant agreed to supply motors to R. S. McLaughlin in Canada, an auto maker, and in 1908 he founded General Motors.[7]
