1800s to 1950s: founding and growth
With a growing portfolio of oil fields and refineries, Sun opened its first service station in Ardmore, Pennsylvania, in 1920. In 1922, it changed its name back to Sun Oil Company and, in 1925, it became a public company via an initial public offering on the New York Stock Exchange. Sun Oil ranked 39th among United States corporations in the value of World War II production contracts. The company expanded internationally following the war. Its first Canadian refinery was built in 1953 in Sarnia, Ontario, home to a burgeoning new petrochemical industry. Sun Oil established a facility at Venezuela's Lake Maracaibo in 1957, which produced over a billion barrels (159 trillion liters) before the operation was nationalized in 1975.
