Passionate about education, Sheldon and Caroline Keck constantly sought new technologies to advance knowledge of conservation materials and improve standards of collection care. Sheldon established the first conservation laboratory at Brooklyn Museum (BkM) in 1934 where he worked together with Caroline for over 30 years. During their tenure at the museum, the couple produced two films: "A Future for the Past" in 1954 and "The Hidden Life of a Painting" in 1962.
