In March of 1926, Goddard launched the world's first liquid-propelled rocket in Auburn, MA, with a small group of witnessed including his wife and several research assistants from nearby Clark University. It reached nearly 41 feet high and crashed nearly 184 feet from it's launch, smashing on impact. Goddard mostly worked independently and was highly secretively-- this is the second of only two papers he published on rocketry, though his impact was immense. Goddard theories and work anticipated many of the developments that made space-flight possible, and he is considered one of the founding fathers of modern rocketry.
