Claim A says Doctors treated hysteria by having women stare at swinging pendulums. Claim B says Doctors invented the vibrator because their hands got tired. Claim B is true, and Claim A is completely made up.
In the late 1800s, "female hysteria" was one of the most commonly diagnosed conditions in Western medicine, and its prescribed treatment was bizarre by modern standards: doctors performed manual pelvic massages on patients until they reached a "paroxysm," believed to relieve symptoms like anxiety and irritability.
The problem? This was exhausting work. Physicians with packed waiting rooms complained of severe hand and wrist fatigue from performing these massages for hours, patient after patient, day after day.
Enter the electro-mechanical vibrator, patented in the 1880s by British physician Joseph Mortimer Granville. It wasn't designed with pleasure in mind at all — it was marketed purely as a labor-saving medical tool, letting doctors treat patients faster and with less physical strain.
The device caught on quickly in clinics and later in home medical catalogs, decades before its true recreational reputation took hold. It's one of the stranger origin stories in medical technology — a convenience gadget born from sheer physician burnout.
The pendulum-staring claim never happened. There's no historical record of doctors using swinging objects as a hysteria treatment — that one's simply invented.
So — did you guess right, or did your hand cramp up trying to decide?
