Harry Kendall Thaw was a wealthy Pittsburgh heir whose sensational 1906 murder of prominent architect Stanford White became one of the defining crimes of the century. His subsequent trials, featuring the first prominent use of the temporary insanity defense and testimony from his wife, showgirl Evelyn Nesbit, captivated the nation and exposed the scandalous lifestyles of the Gilded Age elite. Thaw's life, marked by legal battles, imprisonment, and further erratic behavior, remains a fixture in studies of American celebrity, justice, and media.

Early life and family

Born into immense fortune, he was the son of William Thaw Sr., a Pennsylvania Railroad and coke magnate, and Mary Sibbet Copley. The Thaw family was among the most prominent in Pittsburgh society, with an estate at Lyndhurst. He attended the University of Pittsburgh but did not graduate, instead living a life of leisure funded by a substantial trust fund. His older brother, William Thaw Jr., was a noted World War I aviation pioneer, while his mother was a noted philanthropist for institutions like the University of Pittsburgh and the Pittsburgh Symphony Orchestra.

Murder of Stanford White

On the evening of June 25, 1906, during a performance of the musical *Mam'zelle Champagne* on the rooftop theater of Madison Square Garden in New York City, he approached architect Stanford White. White, a famed designer of the very building and a figure in the New York City social scene, was seated at a table. He then fired three shots at point-blank range, killing White instantly before surrendering to a nearby police officer. The motive was rooted in his marriage to former Florodora showgirl Evelyn Nesbit, whom White had seduced and allegedly assaulted years earlier when she was a teenager, a story that fueled widespread public outrage and media frenzy.

Trials and imprisonment

His first trial in 1907, prosecuted by District Attorney William Travers Jerome, became a national spectacle, with defense attorney Delphin Delmas famously coining the term "Dementia Americana" to describe a temporary insanity provoked by defending a woman's honor. The jury deadlocked. A second trial in 1908 resulted in a verdict of not guilty by reason of insanity, and he was committed to the Matteawan State Hospital for the Criminally Insane in Beacon, New York. In 1913, he escaped to Canada but was extradited. After a series of legal hearings, he was declared sane and released in 1915, with his divorce from Evelyn Nesbit finalized that same year.

Later life and death

After his release, he married socialite Mary Copley in 1916. His later years were marked by continued legal troubles, including arrests for assaults in New York City and Pittsburgh, and lawsuits over his family's estate. He spent much of his time at hotels in Miami and traveled frequently. He died of a heart attack in 1947 at the Roney Plaza Hotel in Miami, Florida, and was interred in the Thaw family plot at Allegheny Cemetery in Pittsburgh.

The scandal has inspired numerous works, most notably the 1955 film *The Girl in the Red Velvet Swing* starring Ray Milland and Joan Collins, and E.L. Doctorow's 1975 novel *Ragtime*, later adapted into a 1981 film and a Broadway musical. It has been featured in television documentaries by networks like PBS and the History Channel, and was a central plot in the 2001 television film *The Murder of Stanford White*. The case is frequently cited in discussions of tabloid media, celebrity trials, and Gilded Age history.
