Nathan Boya (real name William Fitzgerald) was the first African American to go over Niagara Falls. Very little is known about Fitzgerald. He claimed to be self-employed, but others have claimed he worked for IBM. On July 15, 1961, Fitzgerald went over the Horseshoe Falls in a metal ball he helped design called the "Plunge-O-Sphere". Performing stunts on the Falls could only be performed with permission, following the death of William Hill, Jr in 1951. Fitzgerald did not obtain a permit to do his stunt and was arrested and fined after completing it. After the flurry of appearances after his plunge, Fitzgerald did not make public appearances until 1985, when he attended Karel Soucek's funeral and in 1988 protesting discriminatory actions against a scientist he called "Dr. X".
Nathan Boya appeared as a contestant on "I've Got A Secret" on August 30, 1961. His secret was "I went over Niagara Falls in a 6-foot ball." Bill Cullen and Betsy Palmer questioned him. The other panelists, Henry Morgan and Bess Meyerson, recognized him. He was later a contestant on "To Tell The Truth" on an episode that aired January 15, 1962. Three of the four members of the celebrity panel (Tom Poston, Dina Merrill and Johnny Carson) guessed him correctly; Betty White did not.
Interviewed in 2012 for a National Geographic television special about Niagara daredevils, Fitzgerald revealed his reason for his stunt, after decades of silence: He had broken off his engagement, to a woman that he felt he had wronged, and he performed the dangerous stunt as a form of penance. Niagara had been their planned honeymoon destination.
