THE PITTSBURGH STOCK EXCHANGE Eight years after the first oil well was drilled in Pennsyl- vania, at Titusville, by Col. E. L. Drake, the oil traders organized under the name of the Pittsburgh Brokers Associ- ation. The Pittsburgh Oil Exchange was really the first organized market which had a home, being formally organized with a membership of one hundred and eighty on July 25, 1878, with Capt. George W.
