Amy and Isaac Post embodied the temperance, antislavery, and women's rights activism that made Rochester a center of freedom in America. Hicksite Quakers, they lived on this site from the 1840s until Amy's death in 1889, and as conductors on the Underground Railroad they personally aided scores of fugitives from slavery, including as many as 15 at one time. Isaac Post kept an apothecary on Exchange Street near Buffalo Street in the midst of the city's abolitionist activity, left the Quaker Church in 1845 because of its hesitant involvement in abolition, and was converted to Spiritualism by Margaret Fox in 1848. Frederick Douglass stayed in the Post home before they encouraged him to move to Rochester in 1847 to publish The North Star, later Frederick Douglass' Paper; after his death, his 1895 funeral at the Central Presbyterian Church on this site brought him back to the place where he had first stayed in the city. Susan B. Anthony was a close friend of the Posts and attended the second 1848 Women's Rights Convention in Rochester, which Amy Post helped organize. The Central Presbyterian Church built next door to the Posts in 1858, expanded onto the Post lot in 1890, and ministered to poor and undereducated families connected to the nearby Erie and Genesee Valley canals; Anthony's funeral was held there in 1906. In the mid-1970s, after merging with the Brick and First Presbyterian Churches to form Downtown United Presbyterian Church, the congregation donated the building and land to the Hochstein School of Music, founded in 1920 for underprivileged students. The school was named for David Hochstein, nephew of Emma Goldman, an accomplished violinist who enlisted in the U.S. Army Air Corps during the Great War and was killed on October 15, 1918, less than a month before the Armistice was signed on November 11.
