Elizabeth Gloucester (1817–1883) is hardly a household name today, but at the time of her death she was said to be “known to everyone in Brooklyn, New York, the State and in fact throughout a great part of the country.” This fascinating permanent resident of Green-Wood was a wealthy business owner, abolitionist, philanthropist, and friend to some of the leading figures in the nineteenth century, including Frederick Douglass and John Brown—quite a force to reckon with.
