The Society's institutional record is the strongest evidence for its claim that deed can carry a congregation. The Workingman's School opened in 1878 and became the Ethical Culture Fieldston School; district nursing and free kindergarten programmes followed in the same period; Blythedale Children's Hospital dates from 1891; the first Planned Parenthood clinic on the Upper West Side opened in 1950; a homeless women's shelter in 1982. Members were among the founders of the NAACP and the American Civil Liberties Union, and the Society's hall in New York has hosted both. The pattern is consistent and slightly self-effacing: build the institution, then let it become independent, so that the movement's largest achievements are no longer identifiably its own.
