History of ExxonMobil

ExxonMobil traces its roots to Standard Oil, founded by John D. Rockefeller in 1870. After the 1911 Supreme Court breakup of Standard Oil, two of the resulting companies—Standard Oil of New Jersey (Exxon) and Standard Oil of New York (Mobil)—eventually merged in 1999 to form ExxonMobil. The company relocated its headquarters from Irving, Texas, to a new campus in Spring, Texas (north of Houston) in 2015.
