George Joseph Smith (11 January 1872 – 13 August 1915) was an English serial killer and bigamist. In 1915, he was convicted and subsequently hanged for the murders of three women, the case becoming known as the Brides in the Bath Murders. As well as being widely reported in the media, the case was significant in the history of forensic pathology and detection. It was also one of the first cases in which similarities between connected crimes were used to prove deliberation, a technique used in subsequent prosecutions.
