Kilpatrick (September 11, 1869 – September 30, 1927) was an American stunt performer and professional baseball umpire.
Kilpatrick lost his right leg in a rail accident while employed as a miner.
He then began working as a printer and a baseball umpire in several professional leagues including the Wisconsin State League (which he also co-founded), the Montana State League and the Pacific Northwest League.
Kilpatrick gained national and international attention for performing dangerous stunts for amusement.
He performed a feat in which he would ride a bicycle down a specially constructed flight of stairs that would often reach heights of over 100 feet.
In one performance in particular, Kilpatrick rode down a platform of stairs from the roof of Madison Square Garden to the arena floor.
He later developed a similar stunt in which he would drive up a ramp in a steam-powered automobile and descend at a high speed.
