George_Chapman_(murderer)
Seweryn Antonowicz Kłosowski (14 December 1865 – 7 April 1903), better known under his pseudonym George Chapman, was a Victorian era Polish serial killer known as the Borough Poisoner.
Born in Congress Poland, Chapman moved to England as an adult, where he committed his crimes. He was convicted and executed after poisoning three women, but is remembered today mostly because some contemporary police officers suspected him of being the notorious serial killer "Jack the Ripper".
