Long renowned for its Chinese art collection, the Nelson-Atkins Museum of Art will eventually become a destination for French impressionism as well. Friday the museum announced a promised gift of 29 works by impressionist masters such as Renoir, Monet and Seurat from the collection of longtime museum supporters Marion and Henry Bloch (co-founder of H&R Block). The museum's yearlong drive for gifts brought in a total of 400 works from 75 donors.
