Isaac Post

Isaac Post was a radical Hicksite Quakers from Rochester, New York, and leader in the nineteenth-century anti-slavery and women's rights movements.

Also in 1827, Elias Hicks, a relative of the Kirbys, charged that the Religious Society of Friends had lost its way,[4] initiating a split of the "Hicksites", including Isaac Post, from their more orthodox brethren.

When in 1829 Amy Kirby married Isaac Post, criticism for having taken a "Hicksite husband" led to her withdrawal from the Jericho Meeting to which she had belonged since birth.

In addition to her niece and nephew, Amy's maternal responsibilities came to include four more children she had with Isaac: Jacob (1830), Joseph (1834), Matilda (1840), and Willet (1847).

Isaac dedicated much of his time to a very progressive group of Quakers who sought to give both men and women the same rights during the meetings of the Religious Society of Friends.

[citation needed] By the early 1840s, radical Quakers began to hold abolitionist meetings in the Post home, where prominent reform lecturers such as William Lloyd Garrison, Frederick Douglass, Susan B. Anthony, and Sojourner Truth visited and spoke.

He encouraged Isaac T. Hopper, Charles Marriot, and James S. Gibbons when they were disowned by the Religious Society of Friends on account of their outspoken opposition to slavery.
