Mary Elizabeth Eato (also Eaton; September 23, 1844 – February 8, 1915) was an African-American suffragist and teacher.
[3] She received a diploma in teaching from a New York normal school in July 1861, when she was the only colored student graduating at the commencement ceremony.
[7] Among her students were some who themselves became teachers, such as Frances Reynolds Keyser,[5] and Dr. Adena C. E. Minott,[6] founder of a school of mental sciences in Chicago.
[8] During her teaching career, she met Sarah Garnet, the first black woman principal in New York City.
While Garnet founded the Colored Women's Equal Suffrage League of Brooklyn, Eato held a membership there for many years.
