Herman Webster Mudgett, better known by his alias H.H. Holmes, ran a three-story building at 63rd and Wallace in Chicago's Englewood neighborhood during the early 1890s, roughly three miles from the grounds of the 1893 World's Columbian Exposition. Newspapers of the era nicknamed it the “Murder Castle,” and the building has since become one of the most retold true-crime stories in American folklore — often with a body count that historians say the record doesn't actually support.
What's Documented: The Building and the Confessions
Holmes built the structure himself starting around 1887, renting out ground-floor retail space and upper-floor rooms to boarders and hotel guests drawn to the city by the Fair. He was arrested in Boston in 1894, initially on an insurance-fraud scheme unrelated to murder, and confessed to killing 27 people in a widely publicized 1896 statement given shortly before his execution. That confession is where much of the sensational version of the story originates — but researchers who've cross-checked names in it found that several of the supposedly murdered people were later found alive, undermining the confession's reliability as a body count. Holmes was tried and convicted for the murder of his former business associate, Benjamin Pitezel, and was hanged in Philadelphia in May 1896. He's frequently described as America's first documented serial killer, largely because of the number of separate deaths investigators were able to connect to him with reasonable confidence.
What's Actually Verified vs. What Got Exaggerated
According to Adam Selzer, author of a modern biography of Holmes based on court records and period documents, roughly nine deaths can be attributed to Holmes with real historical confidence — a number built from the Pitezel case and a handful of other identifiable victims, not the 27 he claimed or the 200 that some newspapers speculated about at the time. The 200 figure appears to trace back to sensational 1890s press coverage that linked Holmes to the general wave of missing-persons reports connected to the Fair's enormous foot traffic, rather than to any specific evidence tying those disappearances to him. Much of the building's most famous supposed features — soundproofed rooms, hidden chutes to the basement, a gas chamber built into a bedroom — come from that same era of embellished journalism and were never independently verified by investigators at the time; the building itself burned down in 1895, before it could be fully documented or excavated, which has made confirming or debunking many of the specific architectural claims difficult ever since.
Fiction Built From the Case
Holmes's story has been retold heavily in books, podcasts, and documentaries, most famously in Erik Larson's 2003 nonfiction bestseller The Devil in the White City, which pairs Holmes's crimes with the story of the Fair's construction; a planned film adaptation has been discussed for years without being produced. Later retellings, television dramatizations in particular, have tended to repeat the larger, unverified death tolls and the more elaborate “torture castle” details as though they were settled fact, which is part of why the exaggerated version of the story has outpaced the documented one in popular memory.
What's Actually Been Established
It's well documented that Holmes built and operated the Englewood building, that he was convicted and executed for the murder of Benjamin Pitezel, and that his own confession named a much higher number of victims than investigators could substantiate. What hasn't held up is the idea that his death toll reached anywhere close to 200, a figure that traces to unverified period sensationalism rather than case evidence, and many of the building's most infamous physical details can't be independently confirmed since the structure no longer exists.
Frequently Asked Questions
Q1: How many people did H.H. Holmes actually kill?
Historians who've reviewed the case in detail, including biographer Adam Selzer, generally credit Holmes with around nine confirmed deaths, far fewer than the 27 he confessed to or the 200 sometimes cited in older accounts.
Q2: Is the “Murder Castle” still standing?
No. The building burned down in 1895, which is part of why several of its more elaborate reported features were never independently verified by investigators.
Q3: Was Holmes connected to the Chicago World's Fair itself?
He operated his building near the fairgrounds and is said to have rented rooms to visitors in town for the Fair, but he wasn't affiliated with the Exposition itself.
Q4: What was Holmes actually convicted of?
He was tried and convicted specifically for the murder of Benjamin Pitezel, his former business associate, and was executed in 1896.
Q5: Where did the 200-victim claim come from?
It appears to originate in sensationalized 1890s newspaper coverage that linked Holmes to the broader number of people who went missing during the Fair, rather than from any evidence directly tying those disappearances to him.
Q6: Is The Devil in the White City historically accurate?
It's a nonfiction book built on period records and is widely considered a solid account of the documented case, though like most true-crime narratives it presents some contested details, including building specifics, without always flagging the uncertainty.
