Introduction
Henry Howard Holmes, born Herman Webster Mudgett on May 16, 1861, is often considered America’s first known serial killer. Operating primarily in Chicago during the late 19th century, Holmes gained infamy for his elaborate "Murder Castle," a hotel designed for luring, torturing, and killing his victims. His crimes were discovered in 1894, leading to his arrest and eventual execution.The "Murder Castle"
Holmes built a three-story building at 63rd and Wallace in Chicago, later known as the "Murder Castle."
