Mary Garrett Hay

(1857–1928) A suffrage activist who worked closely with Carrie Chapman Catt, Mary was also a temperance worker with the Woman's Christian Temperance Union. She became President of the New York Equal Suffrage League (1910-1918), New York City Woman's Suffrage Party (1912-1918), and the New York City League of Women Voters (1918-1923).

Mary was one of the founders of the National American Women's Suffrage Movement (1910-1918) and, along with Carrie Chapman Catt, was instrumental in obtaining legislation for women's right to vote. Her papers are housed at the Harvard University Library in the Women's Rights Collection. She and Carrie Chapman Catt are buried side by side marked by a single monument inscribed in block letters: "Here lie two, united in friendship for 38 years through constant service to a great cause."
