Elbert Craig Kilpatrick (1850/1 - 1924?) was an American school administrator and teacher who, by his own accounting, had experimented with electrical motors since 1873,[1] before ultimately inventing what he called a compound motor generator, which he claimed used "both positive and negative currents" to produce a self-perpetuating motion.[P]

In 1918, Kilpatrick appeared in Washington D.C. to protest that Garabed Giragossian and the U.S. Government had stolen his design, and that the Garabed generator was entirely based on information given to a government official in a secret interview at Mare Island (Vallejo, California) during January 1916. Six years later, Kilpatrick disappeared, along with his papers regarding the generator, seemingly to never be seen again.[2][3]
