2000 volts of alternating current ruptured Kellmer’s capillaries, forming subcutaneous pools of blood that began to burst as his skin was torn apart. In a panic, the warden doubled the current. 1000 volts of electricity, tested the day before on a luckless horse, knocked Kellmer unconscious, but did not stop his heart.
By all accounts, the execution was a horrific success. The first person to die in an electric chair was William Kellmer, a peddler from Philadelphia who murdered his common law wife in the spring of 1889.
