A prominent minister of First Unitarian during this unsettled period was William Henry Channing, who served from 1853 to 1854. Nationally known as a supporter of social reform, he attended the first National Woman's Rights Convention in Worcester, Massachusetts in 1850 and served on the central committee that coordinated national conventions and other women's rights activities in the following years. In Rochester he worked closely with Susan B. Anthony, writing the call for the Women's Rights Convention she organized there in 1853 and playing a leading role in it. At the 1854 New York State Women's Rights Convention in Albany, which Anthony also organized, he, along with Ernestine Rose, presented petitions to the New York State Assembly that the movement had gathered. He wrote one of the two appeals that Anthony circulated as part of her women's suffrage work in New York state.
