Letitia Mumford Geer
Nurse who designed the modern syringe (1852–1935)
Letitia Mumford Geer (1852– July 18, 1935) was an American nurse who invented the one-hand medical syringe.
Early life
Geer was born in 1852 in New York City to George Warren Geer and Cornelia Matilda Geer (nee Mumford);[1][2][3] Letitia Geer was one of four children.[1]
Career
After spending a few years teaching, Geer moved to Chicago, where she met her husband, Charles Geer, a businessman who was involved in the manufacturing of surgical instruments.[4]
Geer also helped her husband in his business; she thought that the syringes being manufactured were difficult to use because they were often imprecise and unsanitary.
This influenced her to create a more precise syringe. On February 12, 1896, Geer filed for a patent for the one-handed medical syringe design.[5] Her design was given a patent three years later under the publication number
