Jane Toppan was an American serial killer, nicknamed "Jolly Jane". After her arrest in 1901, she confessed to 31 murders. She is quoted as saying that her ambition was "to have killed more people-helpless people-than any other man or woman who ever lived". In 1885, Toppan began training to be a nurse at Cambridge Hospital. While she was there she had a lot of friends, and was well liked. Unlike her early years, where she was described as brilliant and terrible, at the hospital she was well liked, bright and friendly, evoking the nickname 'Jolly Jane'. Once Toppan became close with the patients, she picked her favorite ones. The patients were normally elderly, and very sick. During her residency, she used her patients as guinea pigs in experiments with morphine and atropine; she would alter their prescribed dosages to see what it did to their nervous systems. However, she would spend considerable time alone with patients, making up fake charts and medicating them to drift in and out of consciousness and even getting into bed with them.
She was recommended for the prestigious Massachusetts General Hospital in 1889; there, she claimed several more victims before being fired the following year. She briefly returned to Cambridge but was soon dismissed for administering opiates recklessly. She then began a career as a private nurse and flourished despite complaints of petty theft. She began her poisoning spree in earnest in 1895 by killing her landlord, Israel Dunham and his wife. In 1899, she killed her foster sister Elizabeth with a dose of strychnine. In 1901, Toppan moved in with the elderly Alden Davis and his family in Cataumet to take care of him after the death of his wife, Mattie (whom Toppan herself had murdered). Within weeks, she killed Davis, his sister Genevieve, and two of his daughters, Minnie and Edna.
When we think of inventors, the image that comes to mind is usually that of a frazzled scientist toiling away in a lab, not celebrities pulled from the pages of Us Weekly. However, a number of well-known public figures hold patents for various innovations. Some are related to the work that made them famous, while others are offshoots of hobbies or just a single great idea.
Part of guitar wizard Eddie Van Halen's signature sound was his two-handed tapping technique, but letting all ten fingers fly while simultaneously holding up the guitar's neck could get a bit tricky. Van Halen came up with a novel way to get around this problem, though; he invented a support (top) that could flip out of the back of his axe's body to raise and stabilize the fretboard so he could tap out searing songs like "Eruption." While Van Halen was obviously interested in improving his guitar work, the patent application he filed in 1985 notes that the device would work with any stringed instrument.

It’s probably not surprising that James Cameron—who designed a submersible to take him to the deepest known part of the ocean—will often invent technology to make his films if what he needs doesn’t exist. He holds a number of patents, including US Patent No. 4996938, “apparatus for propelling a user in an underwater environment,” that he and his brother, Michael, created to film The Abyss and patented in 1989. The device is basically an underwater dolly equipped with propellers that makes it easy for a camera operator to maneuver in the water—and allowed Cameron to capture the shots he wanted for the 1989 film, part of which was filmed in an abandoned nuclear reactor.
In 1987 Jamie Lee Curtis designed and patented a disposable diaper that included a waterproof pocket that held baby wipes. She hasn't profited from her idea yet, though, since she refuses to license the patent until diaper companies make biodegradable products.
You know him as a rock legend, but Neil Young also loves trains—so much that he owns a stake in a model train manufacturing company and has an extensive collection. He also holds seven patents related to model trains, including Patent No. US5441223, "Model train controller using electromagnetic field between track and ground."
