Wadham's Oil and Grease Company of Milwaukee

Wadham's Oil and Grease Company of Milwaukee was a chain of filling and service stations that operated in the early 20th century and was headquartered in Milwaukee, Wisconsin. The company's refinery was in Indiana. The company was headed by Harger W. Dodge, who assumed leadership from his father-in-law in 1916. Dodge saw the potential in offering a convenient way for automobile owners to fill their cars with gasoline. He built off-street filling stations with underground tanks for the gasoline and electric pumps to dispense it. Wadham's was purchased by Vacuum Oil Company in 1930. Vacuum Oil was then acquired by Socony, which later became Mobil.
