The New London School explosion occurred on March 18, 1937, when a natural gas leak caused an explosion, destroying the London School of New London, Texas, a community in Rusk County previously known as "London." The disaster killed in excess of 295 students and teachers, making it the worst catastrophe to take place in a U.S. school building. In the mid-1930s, the Great Depression was in full swing, but the London school district was one of the richest in America. A 1930 oil find in Rusk County had boosted the local economy, and educational spending grew with it. The London School, a large structure of steel and concrete, was constructed in 1932 at a cost of $1 million (approx $15.75 million in 2009 dollars). The London Wildcats (a play on the term "wildcatter", for an oil prospector) played football in the first stadium in the state to have electric lights.
