Film Archivist Lepold Krist has been steeped in a century’s worth of WCS history as he catalogues and digitizies historic archive films documenting conservation work globally, and across New York’s zoos and aquariums.  Thanks to funding from the Leon Levy Foundation, which allowed WCS to create the Shelby White and Leon Levy WCS Archives Film Initiative, he is preserving footage of everything from studies of biomechanics of crabs in, to the growth of the Bronx Zoo, to polar research expeditions.  Hannah Kaplan has the story.To see the full catalogue of films, launching in Spring 2024, visit https://library.wcs.org/ Reporting: Hannah KaplanGuest: Leopold Krist
