In 1989, C. Everett Koop (in his last year as Surgeon General) commissioned the "National Museum of Health and Medicine Foundation", a private, nonprofit organization to explore avenues for its future development and revitalization, with the aim of ultimately returning its collection to a venue on the National Mall. Proposed was “a site on land that is located east of and adjacent to the Hubert H. Humphrey Building (100 Independence Avenue, Southwest, in the District of Columbia)”. In 1993, a draft bill authored by Sen. Edward Kennedy proposed $21.8 million for moving the existing collection to a new facility to be constructed on that site. That bill, however, was never introduced owing to political difficulties including objections from Constance Breuer—widow of Marcel Breuer, architect of the Humphrey Building—who objected to the view obstruction that would be entailed by the proposed construction. A letter from the Department of Defense to Koop in the mid-1990s, expressed hope that the NMHM exhibits would "one day be provided the appropriate and prominent home they deserve back at the National Mall in the new National Health Museum". But the DoD backed away from contributing to funding a new museum. The Foundation was superseded by a new organization, dedicated to creating a National Health Museum, which was focused on public health education. Although the effort for a physical museum appears to be defunct, the museum maintains a virtual presence.
