Before the Civil War, people had skimmed oil from creeks, where it
had seeped tp the earths surface. I t wasn’t until 1859 when retired
railroad conductor Edwin L. Drake successfully used a stema engine
to drill for oil near Titusville, Pennsylvania, that removing it from
beneath the earths surface became practical. This technological break
through touched off an oil boom that spread to Kentucky, Ohio,
Illinois and Indiana. Petroleum refining industries grew up in cleveland
and Pittsburgh as entrepreneurs rushed to transform the oil into precious
kerosene. Gasoline, a by product of the refining process, originally
was thrown away.
