Mary Foote Henderson was an American author, real estate developer, and social activist from the U.S. state of New York who was known as "The Empress of Sixteenth Street". Henderson was a notable supporter of women's suffrage, temperance and vegetarianism.

Eunice Newton Foote was an American scientist, inventor, and women's rights campaigner. She was the first scientist to confirm that certain gases warm when exposed to sunlight, and that therefore rising carbon dioxide levels could increase atmospheric temperature and affect climate, a phenomenon now referred to as the Greenhouse effect. Born in Connecticut, Foote was raised in New York at the center of social and political movements of her day, such as the abolition of slavery, anti-alcohol activism, and women's rights. She attended the Troy Female Seminary and the Rensselaer School from age 17–19, gaining a broad education in scientific theory and practice.
