Certificate Vignette The Yellow Cab Co. (of Chicago) was founded by John Hertz in December 1, 1915. The related Yellow Cab and Yellow Truck and Coach Manufacturing Company acquired Walter L Jacobs car rental business. The Yellow Truck Company and rental car business was sold to General Motors in 1926. None of these fully suited the taxicab industry, so on December 31, 1914 the first Yellow Cab Manufacturing Company Cab was designed, and the Model J was released in August 1915. Hertz ran the taxicab company until 1929, when he left to found another rental car company, Hertz Rent-a-Car, which still uses a yellow logo as well. The taxicab company was purchased in 1929 by Morris Markin, who had established Checker Cab Manufacturing Company, with the Checker Taxi, a driver's cooperative. The company was sold again in 1996. According to Yellow Cab Co. tradition, the color (and name) yellow was selected by John Hertz as the result of a survey by the University of Chicago which indicated it was the easiest color to spot. While John Hertz may well have consulted with the University of Chicago on a desireable color, there were yellow taxicabs already in major American cities before l915. Bristol Engineering, a subsidiary of New Departure Manufacturing Co. , produced its' first yellow cabs in l908. It's very likely that when John Hertz bought and borrowed cars for his fledgling business, older yellow cabs from the Chicago area were among his aquisitions. The popular story goes that the wife of the President of New Departure, Nettie Rockwell particularly liked the color yellow and it therefore became the color of the new Rockwell taxicabs.
