(1798 –1872) An abolitionist, Isaac, along with his wife Amy, is credited with assisting the largest number of escaped slaves across the border to Canada from his home, which was an important stop on the Underground Railroad. He was a close friend of Frederick Douglass, and his home was a frequent meeting place for reformists such as Douglass, William Lloyd Garrison, Sojourner Truth and Susan B. Anthony.

Isaac was also known as an early supporter of women’s rights who actively attended women’s rights conventions. In 1853, he signed “The Just and Equal Rights of Women,” a call and resolution for the Woman’s Rights State Convention held in Rochester, New York on November 30 and December 1, 1853.
