There is a lot of misinformation about Letitia Mumford Geer both in English Wikipedia and other Internet sites. She was not married, she did not start a manufacturing company. Most importantly, she did not invent the modern all-glass syringe. She received a patent for a self-administered enema using a novel hook-shaped finger grip that slid past the barrel of the syringe so it could be self-administered with one hand. In previous models the end of the plunger was too far from the barrel to self-administer with one hand. The novelty was the U-shaped plunger grip. Glass barrel syringes had been in use prior to 1895, when she submitted her patent. Alexander Wood designed the modern all-glass syringe in 1851. There are also images purporting to be of Letitia Mumford Geer, and there is no known image of her extant.
