John Hurlburt (1867–1929), dubbed the “electric chair executioner,” was a key figure in early 20th-century American penal history, performing 140 executions at Sing Sing Prison in New York, including the infamous case of Julius Miller in 1926. Starting as an electrician at Auburn Prison—site of the world’s first electric chair execution in 1890—Hurlburt’s career exemplified the grim profession’s toll, leading to his resignation and tragic suicide amid personal anguish. Trained under Edwin Davis, the first “state electrician” who executed 240 people, Hurlburt’s work involved meticulous preparation for “Old Sparky,” but the psychological burden—witnessing convulsions, smoke, and the smell of burning flesh—drove many executioners to depression, addiction, and family secrecy. His 140th execution, meant to be routine, became his last, highlighting the human cost of state-sanctioned killings. This story, set against the backdrop of Sing Sing’s “Death House,” reflects the era’s retributive justice and the executioner’s isolated life. Examining it objectively reveals the ethical horrors of capital punishment, underscoring reforms like New York’s 1963 abolition and the need to learn from history to prioritize rehabilitation over vengeance.

John Hurlburt was born in September 1867 in Auburn, New York, beginning his career as an electrician at Auburn Prison, where the electric chair debuted with William Kemmler’s botched execution on August 6, 1890—described as “horrible” by inventors like George Westinghouse and Thomas Edison. Hurlburt assisted Edwin Davis, the world’s first professional electric chair executioner, who trained him and Robert Greene Elliott. Davis, executing 240 from 1890 to 1914, created the “Black Thursday” record by killing seven in one day on August 12, 1912.
Hurlburt replaced Davis at Sing Sing, New York’s primary execution site from 1915. His 140 executions included notorious cases, but the psychological strain was immense—post-traumatic stress, depression, and substance abuse plagued executioners. During Julius Miller’s 1926 execution, Hurlburt meticulously attached electrodes soaked in saline to prevent burning, yet sweat beaded on his face from stress. Miller, strapped in, convulsed under 1,750 volts, smoke rising as his body charred— a common, horrifying sight.

Personal life compounded Hurlburt’s torment: his wife Mattie’s chronic illness racked up medical bills, forcing him to continue despite hatred for the job. Paid $150 per execution (plus $50 for multiples), he hid his profession from family and friends, fearing revenge. Traveling for executions in states like New Jersey and Massachusetts, Hurlburt grew irritable, throwing objects in frustration.
Mattie’s death in September 1925 devastated him; he resigned after two more executions on January 16, 1926, stating he was “sick of killing.” Elliott succeeded him, executing 387 until 1939. Hurlburt’s life ended in suicide on February 22, 1929, in his Auburn basement with a prison-found pistol—echoing the fate of many executioners entangled in domestic violence or despair.
Sing Sing’s “Death House,” dubbed the “Slaughterhouse” by inmates, executed 614 from 1891 to 1963, with the last in August 1963 (Eddie Lee Mays). Now a vocational center, “Old Sparky” is exhibited at Newseum in Washington, D.C.

John Hurlburt’s career as Sing Sing’s “electric chair executioner,” ending with his 140th kill and personal tragedy, exemplifies the profound toll of state-sanctioned death on those who administered it. From meticulous preparations amid moral anguish to hidden lives fearing retribution, his story reveals the human cost behind “justice.” By reflecting objectively, we confront how executions destroyed not just condemned but executioners, fueling reforms like New York’s abolition. This history urges societies to reject capital punishment’s cycle of trauma, promoting rehabilitation, mental health support, and ethical alternatives to build compassionate systems free from such darkness.
