"To resist the Standard Oil Trust, several small wildcat enterprises joined forces in 1887 in Lima, Ohio to form “The Ohio Oil Company,” with Henry M. Ernst serving as its first president. The alliance only delayed the inevitable however, and in 1889, the Standard Oil Trust added Ohio Oil Company to its growing list of acquisitions....." In 1911, growing anti-trust sentiment in the country led to the U.S. Supreme court decision compelling the breakup of Standard Oil. Ohio Oil Company once again became an independent company(American Oil & Gas Historical Society). This booklet recounts this history and describes the company's expansion into various fields (in the midwest, Kansas, Oklahoma, and Texas) and markets over the years.
