Capt. Anthony Francis Lucas, an experienced mining engineer and salt driller, drilled a well to find oil at Spindletop Hill. On the morning of January 10, 1901, the little hill south of Beaumont, Texas began to tremble and mud bubbled up over the rotary table. A low rumbling sound came from underground, and then, with a force that shot 6 tons of 4-inch (100 mm) diameter pipe out over the top of the derrick, knocking off the crown block, the Lucas Gusher roared in and the Spindletop oil field was born. Spindletop became the focus of frenzied drilling; oil production from the field peaked in 1902 at , but by 1905 production had declined 90% from the peak.
