American suffragist, abolitionist, and mathematician

Chloe Angeline Stickney Hall (November 1, 1830 – July 3, 1892) was an American mathematician and suffragist. She was married to astronomer Asaph Hall and collaborated with her husband in searching for the moons of Mars, performing mathematical calculations on the data he collected.

Angeline Stickney was born to Theophilus Stickney and Electa Cook on November 1, 1830. In 1847, she took three terms of study funded by her cousin, Harriette Downs, at Rodman Union Seminary. Stickney was able to attend New York Central College with help from her sister Ruth and by teaching at the college. She majored in science and mathematics, completed coursework in calculus and mathematical astronomy, and graduated with the college's first class, in 1855. New York Central College was a progressive school where students of modest means, including women and free African Americans, could earn a college degree. It was here that she became passionate about the causes of women's suffrage and the abolition of slavery. Angeline Stickney and Asaph Hall met at Central College. Stickney was two years ahead of Hall. She was his instructor in geometry and German. During their days together as teacher and student, Hall and his classmates would devise questions and problems that they were convinced Stickney could not solve, yet she reportedly never failed to solve them.
