On April 7, there will be an event to celebrate the publication of Harriet Hosmer: A Cultural Biography at the Renee and Chaim Gross Foundation. Born in Austria in 1904, Chaim Gross emigrated to the United States in 1921. He became a well known sculptor, working primarily in wood, and was a founding teacher of sculpture at the New School. The event will take place in his studio, which is filled with his work. I don’t believe the models from the picture linked to will be there; if so, they are likely to be clothed.
