The first human cannonball, launched in 1877 at the Royal Aquarium in London, was a 14 year-old girl called "Zazel", whose real name was Rossa Matilda Richter. She was launched by a spring-style cannon invented by Canadian William Leonard Hunt ("The Great Farini"). She later toured with the P.T. Barnum Circus. Farini's cannon used rubber springs to launch a person from the cannon, limiting the distance he or she could be launched. "Human Cannonball." Wikipedia. Wikimedia Foundation, 27 Dec. 2013.
