A white woman who ran a school for girls in Connecticut. In 1832 she admitted a local black girl. When the parents of her white students demanded the black girl be removed, she dismissed all the white students and re-opened the school with all black students.
Prudence Crandall (September 3, 1803 - January 28, 1890), a schoolteacher raised as a Quaker, stirred controversy with her education of African-American girls in Canterbury, Connecticut. Her private school, opened in the fall of 1831, was boycotted when she admitted a 17-year-old African-American female student in the autumn of 1833; resulting in what is widely regarded as the first integrated classroom in the United States.
She is Connecticut's official State Heroine.
Prudence Crandall was born on September 3, 1803 to Pardon and Esther Carpenter Crandall, a Quaker couple in the Hope Valley area in the town of Hopkinton, Rhode Island.  At the age of 17, her father decided to move the family to the small town of Canterbury, Connecticut.  She attended the Friends' Boarding School in Providence, Rhode Island  and later taught in a school for girls in Canterbury. In 1831, she returned to run the newly established Canterbury Female Boarding School, which she purchased with her sister, Almira. 
Integration of the boarding school
In the fall of 1832, a young woman by the name of Sarah Harris, the daughter of a free African American farmer in the local community,  asked to be accepted to the school in order to prepare for teaching other African Americans. Her father owned a small farm near Canterbury, and Harris even attended the same district school as the white girls who were attending Crandall's school as teenagers. Clearly, the only difference between Harris and the other white pupils was their skin color.
Although she was uncertain of the repercussions that this would cause, Crandall eventually allowed Harris to join her school. Following her admission, many prominent townspeople objected and pressured to have Harris dismissed from the school, but Crandall refused. Families of the current students removed their daughters.
Consequently, Crandall ceased teaching white girls altogether and open up her school strictly to African American girls.Crandall temporarily closed the school and began openly recruiting students on March 2, 1833, when William Lloyd Garrison, a supporter of the school, placed advertisements for new pupils in his newspaper The Liberator. Her advertisement announced that on the first Monday of April 1833 she would open a school “for the reception of young ladies and little misses of color, ... Terms, $25 per quarter, one half paid in advance.” In the list of references were the names of Arthur Tappan, Samuel J. May, William Lloyd Garrison, and Arnold Buffum.
As word of the school passed up and down the Atlantic Seaboard, African American families began sending their daughters from out of state to the school. On April 1, 1833, twenty African-American girls from Boston, Providence, New York, Philadelphia, and surrounding areas in Connecticut arrived at Miss Crandall's School for Young Ladies and Little Misses of Color.
The new school
With the school now open, Crandall was teaching a variety of subjects including reading, writing, arithmetic, English grammar, geography, history, natural and moral philosophy, chemistry, astronomy, drawing and painting, music and the piano, and even the French language. The students were required to pay $25 per quarter, paying half of that sum in advance. This money covered tuition, board, and washing, while books and stationery were purchased and provided to the girls at a discounted price. Crandall's excitement and sense of accomplishment at running a school to help young black women was short-lived because of the immediate ostracism and criticism she faced from her community, and even the state.
Citizens of Canterbury at first protested the school and then held town meetings "to devise and adopt such measures as would effectually avert the nuisance, or speedily abate it..." Unable to shake Ms. Crandall's spirit, the town response escalated into warnings, threats,and acts of violence against the school. Crandall was faced with great local opposition and they had no plans to back down.
On May 24, 1833 the Connecticut Legislature passed "The Black Law" prohibiting such a school with African American students from outside the state without the town's permission. In July, Crandall was arrested and placed in the county jail for one night and then released under bond to await her trials.
Under Black Law, the townspeople refused any amenities to the students or Crandall, closing their shops and meeting houses to them. Stage drivers also refused to provide them with transportation and even the town doctors would not attend to their needs. To make matters worse, the townspeople also poisoned the school's well—its only water source—with animal feces and then prevented Crandall from obtaining any water from other sources. It was difficult for Crandall to run her school when she had no resources to keep it standing. But she continued to teach the young women angering the community even further.
Crandall's students also suffered from the injustices of their environment. One 17-year-old student, Anna Eliza Hammond, was even arrested at one point; however, with the help of New York abolitionist Samuel May, she was able to post bail bonds with through collections and donations of $10,000.
In response to a local reverend's support of Crandall, lauded Connecticut politician Andrew T. Judson, stated that,"...we are not merely opposed to the establishment of that school in Canterbury; we mean there shall not be such a school set up anywhere in our state. The colored people can never rise from their menial condition in our country."
At word of Crandall's trials, a prominent abolitionist, Arthur Tappan of New York, donated $10,000 to hire the ablest lawyers to defend Crandall throughout her trials, the first of which opened at the Windham County Court on August 23, 1833.Constitutionality of the Connecticut law regarding the education of African Americans was the driving force of the cases.
The defense argued that African Americans were citizens in other states, so therefore there was no reason why they should not be considered as such in Connecticut. Thus, they focused on the deprivation of their rights under the United States Constitution. In contrast, the prosecution denied the fact that freed African-Americans were citizens in any state, and the county court jury ultimately failed to reach a decision for the cases. 
Although a second trial in Superior Court decided against the school, the case was taken to the Supreme Court of Errors on appeal in July of 1834. At the conclusion of this appeal, the Supreme Court of Connecticut reversed the decision of the lower court, dismissing the case on July 22 on the grounds of a lack of evidence.
The judicial process had not stopped the operation of the Canterbury school, but the townspeople's violence against it increased. The windows were smashed with heavy iron bars as the vandalism continued. The public was so angry at the dismissal of the case that on September 9, the school was set on fire. For the safety of her students, her family and her self, Prudence Crandall decided to close her school on September 10, 1834. 
In August of the same year the school closed, Prudence Crandall married the Rev. Calvin Phileo. Mr. and Mrs. Philleo moved out of state to Massachusetts, then lived in New York, Rhode Island, and Illinois, where Calvin Phileo died. Following the death of her husband, Prudence Crandall relocated to Elk Falls, Kansas, where a state historical marker commemorates her contributions.
Connecticut repealed the Black Law in 1838, and later recognized Prudence Crandall with an act of the state legislature, prominently supported by Mark Twain, providing her with a $400 yearly pension in 1886 (about $9,500 in 2009 dollars).
Crandall's school still stands in Canterbury, Connecticut, and currently serves as the Prudence Crandall museum, run by the Connecticut Commission on Culture and Tourism. The Prudence Crandall House in Canterbury, Connecticut, was declared aNational Historic Landmark in 1991.
In Enfield, Connecticut, an elementary school of Enfield Public Schools carries the namesake Prudence Crandall Elementary School.
In 1995, the Connecticut General Assembly designated Prudence Crandall as the state's official heroine.
