American educator Prudence Crandall was born #OTD in 1803.
She ran the Canterbury Female Boarding School, which became the 1st school for black girls in the United States. The decision to admit Black students led to intense opposition. Local residents passed a law specifically targeting her school, known as the Black Law, which made it illegal to operate a school for Black students from out of state without local permission.
