Prudence Crandall (September 3, 1803 - January 28, 1890) was an American schoolteacher. In 1831 her private school was boycotted when she admitted an African-American girl. Consequently, Crandall ceased teaching white girls altogether and opened up her school strictly to African-American girls. In 1833, African-American girls from Boston, Providence, New York, Philadelphia, and Connecticut arrived at Miss Crandall's School for Young Ladies and Little Misses of Color. The the Connecticut legislature passed the Black Law, which prohibited a school with African-American students from outside the state without the town's permission. Crandall was arrested and placed in the county jail and released under bond to await her trials. The case made it to the Supreme Court of Errors on appeal where they reversed the decision of the lower court, and dismissed the case. The public was so angry that the school was set on fire. For the safety of her students, her family and herself, she closed her school. Connecticut repealed the Black Law in 1838. Crandall died in 1890 at the age of 86. She is Connecticut's official State Heroine.
