Museum of Quackery

The Online Home of the

Museum of Questionable Medical Devices

Founded and curated by Bob McCoy, the museum grew into the world’s largest collection of medical quackery — more than 250 devices dreamed up to cure the human body without the bother of science or common sense. In 2002 the collection was donated to the Science Museum of Minnesota, where it’s on display today in the Weighing the Evidence exhibit. This site lives on as a tribute to the museum — and to Bob.

“Come one, come all! Devious displays of quackery, fraud, deceit and deception — the largest collection of medical chicanery and mayhem ever assembled under one roof. Step right up!”

Soap that sudses off pounds, weight-reduction glasses, the “magic” of radio waves… quackery is alive and well on the banks of the mighty Mississippi.  See the full device collection →

Sound like a carnival barker? A snake-oil salesman? A sideshow shill?

Well — you’re close. Proprietor Bob McCoy was a veritable encyclopedia of the world’s most inane and useless information about how to cure and/or comprehend whatever may ail or puzzle you. That’s Bob getting a “phrenology” reading on a psycograph — a machine that measures the bumps on your head to rate you on 35 character traits, from intelligence and spirituality to suavity and chastity.

Dubbed “The Quackery Hall of Fame” by the Copley Wire Service, the museum was the world’s largest display of what the human mind has devised to cure itself without the benefit of either scientific method or common sense — drawing on major collections from the American Medical Association, the U.S. Food and Drug Administration, the St. Louis Science Center, the Bakken Library, and the National Council Against Health Fraud. The famed collection was donated to the Science Museum of Minnesota in 2002, and today lives on in their Weighing the Evidence exhibit.
