Thomas Hopkins Gallaudet was born in 1787 in Philadelphia and moved to Hartford as a teenager. He attended Yale University and was interested in educating deaf children after meeting his neighbor's deaf daughter. He traveled to Europe to study methods for teaching the deaf and then opened the first American school for the deaf in Connecticut. The school was a success and grew rapidly, helping establish American Sign Language and spread the idea of deaf education. Gallaudet later married one of his students and had eight children before passing away in 1851, though his work continued through his son who opened the first college for the deaf.
