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
