1. Historical Context: Houston’s Legacy as an Energy Innovator
Houston’s rise began with the 1901 Spindletop oil discovery, catalyzing Texas’ oil boom. The city later became a hub for petroleum engineering, driven by institutions like Rice University and the Texas Oil Boom. Key innovations such as deep-water drilling (pioneered by companies like Schlumberger) and the development of petrochemical complexes established Houston’s global dominance. The establishment of NASA’s Johnson Space Center in the 1960s further cemented its culture of technological ambition.
