William Kemmler is known in American legal and penal history as the first person put to death by electrocution. Convicted of the murder of Matilda "Tillie" Ziegler, his common‑law wife, Kemmler's conviction and execution marked a turning point in the search for methods thought to be more humane than hanging.

Crime and trial

Kemmler was arrested, tried and convicted in New York State for the killing of Ziegler. The case drew public attention partly because the state had approved a new method of execution — electrocution — as an alternative to hanging. His trial and appeals took place against this novel legal and technological backdrop.

Execution and immediate aftermath

Kemmler was put to death at Auburn Prison in 1890 by means of the electric chair, a device that had been proposed in the 1880s as a supposedly more merciful form of capital punishment. Contemporary reports described that the first application of electricity did not quickly produce death and that attendants applied additional shocks; observers later reported smoke and burning, accounts that fed debate about the method's humaneness.

Appeals arising from the case reached the United States Supreme Court. In a decision often cited in discussions of the Eighth Amendment, the Court held that execution by electrocution did not in itself constitute "cruel and unusual punishment." The ruling cleared the way for other states to adopt electrocution as an approved execution method.

Context and legacy

The electric chair's adoption occurred during a period of rapid technological change and intense public debate about the death penalty. Inventors, physicians and politicians argued about whether electricity could make executions quicker and less painful. The early years after Kemmler saw several other executions by electrocution, though hanging remained common for some time. The Kemmler case remains a touchstone in conversations about capital punishment, evolving standards of decency, and the role of technology in state practices of punishment.
