H.H. Holmes | Biography & Facts (2024)

H.H. Holmes (born May 16, 1861?, Gilmanton, New Hampshire, U.S.—died May 7, 1896, Philadelphia, Pennsylvania) was an American swindler and confidence trickster who is widely considered the country’s first known serial killer.

Mudgett was born into a wealthy family and showed signs of high intelligence from an early age. Always interested in medicine, he allegedly trapped animals and performed surgery on them; some accounts of his life even suggest that he killed a childhood playmate. Mudgett attended medical school at the University of Michigan, where he was a mediocre student. In 1884 he was nearly prevented from graduating when a widowed hairdresser accused him of making a false promise of marriage to her.

In 1886 Mudgett moved to Chicago and took a job as a pharmacist under the name “Dr. H.H. Holmes.” Soon afterward he apparently began killing people in order to steal their property. The house he built for himself, which would become known as “Murder Castle,” was equipped with secret passages, trapdoors, soundproof rooms, doors that could be locked from the outside, gas jets to asphyxiate victims, and a kiln to cremate the bodies. At the reputed peak of his career, during the World’s Columbian Exposition in Chicago in 1893, he allegedly seduced and murdered a number of women, typically by becoming engaged to them and then killing them after securing control of their life savings. Mudgett also required his employees to carry life insurance policies naming him as beneficiary so that he could collect money after he killed them. He sold the bodies of many of his victims to local medical schools.

In 1893 Mudgett was arrested for insurance fraud after a fire at his home, but he was soon released. He then concocted a scheme with an associate, Ben Pitezel, to defraud an insurance company by faking Pitezel’s death. After Pitezel purchased a $10,000 life insurance policy, he and Mudgett traveled to Colorado, Missouri, New York, Pennsylvania, Tennessee, and Texas, where they committed other acts of fraud (along the way, Mudgett also married). Returning to Missouri, Mudgett was arrested for fraud and briefly jailed in St. Louis. While in jail he met Marion Hedgepeth, a career criminal who agreed to help Mudgett in the insurance scheme with Pitezel. Meanwhile, Pitezel moved to Philadelphia and opened a fake patent office to swindle inventors. After his release from jail, Mudgett traveled to Philadelphia and killed Pitezel. He then convinced Pitezel’s widow, who had been aware of her husband’s involvement in the insurance scheme, that her husband was still alive, later giving her $500 of the money he collected. Worried that some of Pitezel’s five children might alert the authorities, Mudgett killed three of them. Insurance investigators were alerted to the fraud by Hedgepeth, and Mudgett was arrested in Boston, Massachusetts, in 1894. He was tried in Philadelphia for the murder of Pitezel and was sentenced to death by hanging.

Mudgett confessed to 27 murders (he later increased the total to more than 130), though some researchers have suggested that the real number exceeded 200. Mudgett sold his story to the Hearst Corporation for $10,000.
