Front and rear view of the electric chair used for Kemmler's execution. Insert A: the electrode to press against the head. The first electric chair was produced by Harold P. Brown and Arthur Kennelly. To prove the danger of AC electricity and its suitability for executions, Brown and Edison publicly killed many animals with AC for the press in hopes of associating alternating current with electrical death. The first person sentenced to be executed by the electric chair was William Kemmler, a convicted murderer on August 6, 1890. The first 17 second passage of current through Kemmler caused unconsciousness, but failed to stop his heart and breathing. After confirming Kemmler was still alive a second passage ofcurrent was called for. The generator needed time to recharge, however. In the second attempt, Kemmler was shocked with 2, 000 volts. Blood vessels under the skin ruptured and bled, and the areas around the electrodes singed. The entire execution | |
