Hertz had extensive and complex business interests, mainly in the transport sector. When Chicago Morning Herald, then called the
Chicago Record, merged with another paper, Hertz lost his job. Although he couldn't drive, in 1904 he found a job selling cars at the suggestion of a friend. In 1907, he had a fleet of seven used cars employed as cabs. By 1925, the Yellow Cab Company was owned by the "Chicago Yellow Cab Company," which in turn was owned by Hertz,
Parmelee and other investors. In that year he established
The Omnibus Corporation to control both the Chicago Motor Coach Company and the
Fifth Avenue Coach Company in New York. In 1925, Hertz held these positions: • President of the
Yellow Cab Company • Chairman
Benzoline Motor Fuel Company • Chairman
Chicago Motor Coach Company • Chairman
Fifth Avenue Coach Company • Chairman
New York Transportation Company • Chairman
Omnibus Corporation of America • Chairman
Yellow Sleeve-Valve Engine Works • Chairman
Yellow Truck and Coach Manufacturing Company In 1926, he sold a majority share in Yellow Cab Manufacturing Company together with its subsidiaries, Yellow Coach Manufacturing Company and "Hertz Drive-Ur-Self," to
General Motors. With the sale, Hertz joined GM's board of directors. He then sold his remaining interest in the
Yellow Cab Company in 1929 following the firebombing of his stables, where 11 horses were killed. Hertz also became a partner at
Lehman Brothers investment bank in
New York City. In 1933,
Robert Lehman sold Hertz a minority interest in Lehman Brothers, and Hertz remained a member of the firm until his death. In 1938, Hertz was prepared to buy
Eastern Air Lines from
General Motors but the airline's General Manager,
Eddie Rickenbacker, was able to raise sufficient financing to acquire Eastern before Hertz could exercise his option. In 1943 he sold his remaining interest in Yellow Coach Manufacturing Company to General Motors. Using The Omnibus Corporation he re-purchased the car rental business from General Motors in 1953. The Omnibus Corporation then divested itself of its public transport interests, changed its name to
The Hertz Corporation and was listed on the
New York Stock Exchange the following year. ==Personal life==
