Herman Webster Mudgett, better known as H.H. Holmes, became one of America's earliest infamous serial killers after carrying out a series of murders during the late nineteenth century. Operating from a specially designed building in Chicago that later became known as the "Murder Castle," Holmes used deception, fraud, and false identities to lure victims. Although he confessed to 27 murders before his execution, historians believe the true number of victims remains uncertain. His case remains one of the most famous in American criminal history.

Harold Frederick Shipman became one of the most prolific serial killers in modern history after murdering patients under his care while working as a general practitioner in England.
