This was taken on the Brooklyn Bridge of traffic leaving Manhattan with the ubiquitous Yellow Cab leading the way.
There are many Yellow Cabs operators around the world (some with common heritage, some without). The original Yellow Cab Company, based in Chicago, Illinois one of the largest taxicab companies in the United States.
In 1908, Albert Rockwell, (founder and General Manager of the New Departure Manufacturing Co. of Bristol, Connecticut) traveled to Europe to evaluate their taxi systems, hoping to develop a similar one in Washington, D.C. Wyckoff, Church and Partridge’ had a number of orange-yellow colored Rockwell taxicabs operating on Manhattan streets in 1909. By March 1910, the Connecticut Cab Co. (essentially the directors of New Departure Manufacturing Co.) assumed operating control of Wyckoff, Church and Partridge’s taxis.
The ‘Yellow Taxicab Co.’ was incorporated in New York on April 4, 1912. Its fares that year started at 50¢/mile (about $11.38 today.) Among its directors and major stockholders were Albert F. Rockwell and the Connecticut Cab Co. Shortly after incorporation the Yellow Taxicab Co. merged with the Cab and Taxi Co., and with the strength of Connecticut Cab with whom its name was interchangeably used, the young business assumed a large share of the New York market. Its independent corporate life was fairly short, however, as fare wars and restrictions forced a merger with the Mason-Seaman Transportation Co. on March 3, 1914. www.kerstenbeck.com
