Drake (right) in front of the well. Drilled by Edwin Drake in 1859, along the banks of Oil Creek, it is the first commercial oil well in the United States. Drake Well was listed on National Register of Historic Places and designated a National Historic Landmark in 1966. It was designated a Historic Mechanical Engineering Landmark in 1979. The well was designated a National Historic Chemical Landmark in 2009, on the sesquicentennial of the strike. Before the Drake well, oil-producing wells in the United States were wells that were drilled for salt brine, and produced oil and gas only as accidental byproducts. Historians have noted that the importance of the Drake well was not in being the first well to produce oil, but in attracting the first great wave of investment in oil drilling, refining, and marketing.
