Overview
Bour-Davis was an American automobile marque and manufacturer active during the first postwar period of the United States automobile industry. The name combined the surnames of two of the company's founders, Charles J. Bour and Robert C. Davis. Production began in Detroit in 1916, initially positioning the Bour-Davis as a relatively expensive car rather than a basic mass-market automobile. Contemporary models were notable for several styling and construction details, particularly the slightly forward-set radiator and, on the Detroit- and Frankfort-built Model 17 and Model 18B, a distinctive radiator shell that was both pointed and subtly slanted. The business changed hands and locations several times. In 1917, the company was reorganized after being taken over by the Shadburne brothers of Chicago, with manufacturing transferred from Detroit to Frankfort, Indiana. The new owners announced plans to produce automobiles of their own design, although available historical accounts indicate that it is uncertain whether those proposed vehicles ever reached production. In 1918, the Bour-Davis manufacturing rights were acquired by the Louisiana Motor Car Company. Production subsequently moved south, first to Louisiana and ultimately to Shreveport, where the company sought to give the automobile a strong regional identity. Under Louisiana ownership, Bour-Davis was promoted as the “Pride of Shreveport.” The company also sponsored a contest through the Shreveport Times to find a new name for the car. The winning suggestion was “Louisianne,” but the proposed replacement name was never adopted, and the Bour-Davis identity remained in use. The Louisiana-built cars retained distinctive design features, including a radiator mounted slightly ahead of the front axle and a leather front-seat treatment that continued over the top of the seat and down toward the rear floor. Later models included the Model 20, Model 21, and Model 21S. The Model 21 and Model 21S used Continental straight-six engines, reflecting the period's reliance on purchased engines among smaller automobile manufacturers. Bour-Davis vehicles were priced at the upper end of the market for their era: listed prices rose from approximately $1,250–$1,500 in 1916 to about $1,650 in 1919, while a 1920 Model 20 touring car was priced at $1,700 and a 1922 Model 21S touring car at $2,300. These prices placed the cars above many inexpensive American automobiles and suggest that the marque competed on equipment, styling, and perceived quality rather than volume. In 1923, the business was taken over by J. M. Ponder and the Ponder Motor Manufacturing Company. Financial weakness prevented the new ownership from restarting production, and the Bour-Davis marque disappeared. Approximately 1,500 Bour-Davis cars were produced between 1916 and 1922. The surviving cars are now primarily of interest to collectors and historians of early American automobile manufacturing, particularly because they illustrate the industry's regional production shifts, frequent ownership changes, and dependence on limited-volume manufacturing operations.
History
Bour-Davis emerged during the expansion of the American automobile industry in the 1910s. The marque took its name from Charles J. Bour and Robert C. Davis, two of the company's founders, and began manufacturing automobiles in Detroit in 1916. Its cars were not positioned as the cheapest vehicles available. Prices in the first production year were reported at approximately $1,250 to $1,500, placing the marque in a higher-priced segment of the market. The early cars included the Model 17 and Model 18B. Examples built in Detroit and later in Frankfort were recognizable by a slightly slanted, pointed radiator design. Other construction and styling details included a radiator set somewhat ahead of the front axle and a leather front seat whose covering extended over the seat top and down toward the rear floor. These features gave the cars a visual and material identity at a time when small manufacturers sought ways to distinguish themselves from larger producers. In 1917, the company was taken over by the Shadburne brothers of Chicago. Following a reorganization, manufacturing moved from Detroit to Frankfort, Indiana. The new owners stated that they intended to build cars based on their own designs, but historical accounts do not establish that these plans resulted in a separate production line. The company changed ownership again in 1918, when the Louisiana Motor Car Company acquired the Bour-Davis manufacturing rights. Production was moved to Louisiana and ultimately centered in Shreveport. The Louisiana Motor Car Company attempted to connect the marque closely with its new manufacturing base. Its advertising presented Bour-Davis as the “Pride of Shreveport,” and a contest held through the Shreveport Times invited suggestions for a replacement name. “Louisianne” won the contest, but the name was never put into regular use. The car therefore continued to be marketed under the Bour-Davis name despite the change in ownership and location. Later production included the Model 20, Model 21, and Model 21S. The Model 21 and Model 21S were equipped with Continental straight-six engines. Prices continued to reflect the company's limited-volume, comparatively upscale position: the 1920 Model 20 touring car was listed at about $1,700, while the 1922 Model 21S touring car reached approximately $2,300. The brand's production run ended after 1922, with total output estimated at roughly 1,500 automobiles. In 1923, J. M. Ponder and the Ponder Motor Manufacturing Company acquired the business. The new owner lacked sufficient financing to restart production, so no meaningful continuation of Bour-Davis manufacturing followed. The marque consequently became a defunct automobile brand. Surviving examples, including restored touring cars, preserve evidence of the company's distinctive designs and provide a record of the difficult operating conditions faced by small American automobile manufacturers that relied on multiple ownership changes and regional production moves.
