Thomas A. Edison is remembered as the inventor of the first practical electric light bulb and the motion picture camera. However, many people don't remember that Edison electrocuted cats, dogs, horses, and an orangutan with alternating current (AC) electricity as part of a campaign to bolster support for his allegedly safer direct current (DC) method of electricity distribution. His "War of Currents" rivalry with George Westinghouse and Nikola Tesla, both AC proponents, ultimately led to the electrocution of a six-ton zoo elephant named Topsy on Jan. 4, 1903.
In the late 1880s, Thomas Edison launched a public campaign against alternating current. "I remember Tom [Edison] telling them that direct current was like a river flowing peacefully to the sea, while alternating current was like a torrent rushing violently over a precipice,” Westinghouse recalled.
Edison sent Professor Harold Brown on a tour to demonstrate the dangers of AC by electrocuting dogs, cats, horses, cows, and even an orangutan on stage. The demonstrations led some people to believe that electrocution was a valid form of execution.
Electrocution of Topsy the Elephant on Jan. 4, 1903
On Aug. 6, 1890, New York State performed the first execution by electrocution with the assistance of Thomas Edison's engineers. Professor Brown illegally purchased a Westinghouse generator and with two surges of electricity, one of them lasting more than one minute, electrocuted murderer William Kemmler to death. After Kemmler's execution, "Westinghousing" became a slang term for the death penalty administered by electrocution.
Having already electrocuted cattle and a human, Edison was ready for his largest challenge - a six-ton elephant. On Jan. 4, 1903, Edison filmed the electrocution of Topsy the Elephant to demonstrate the dangers of (AC), which threatened the profitability of his DC method of electricity distribution.
The Luna Park Zoo at Coney Island decided that Topsy the Elephant was a danger to visitors after the 10-foot-high Indian elephant killed three trainers in three years. One of the victims was J. Fielding Blunt, a handler who tried to feed Topsy a lit cigarette. The zoo built a scaffold to publicly hang Topsy, but opposition by the Society for the Prevention of Cruelty to Animals led the owners to turn to Thomas Edison who had been electrocuting animals since the 1880s.
As a precaution in case the electrocution was ineffective, Topsy was fed cyanide-laced carrots before over 6,000 volts shot through her body in front of a crowd of 1,500 spectators. The precautions were unnecessary, as Topsy was killed nearly instantly. Edison filmed the entire scene, and released his motion picture Electrocuting an Elephant in 1903. A memorial for Topsy opened 100 years later on July 23, 2003, at the Coney Island Museum.
