William Francis Kemmler (May 9, 1860 – August 6, 1890) was an American murderer who was the first person executed by electric chair. He was convicted of murdering Matilda "Tillie" Ziegler, his common-law wife, a year earlier. Although electrocution had previously been successfully used to kill a horse, Kemmler's execution did not go smoothly.
