Federally funded research and development centers (FFRDCs) are a unique class of research and development (R&D) facilities that share aspects of private and public ownership. These institutions have directly and indirectly contribute to atmospheric sciences under the sponsorship of several federal agencies. NSF sponsors five FFRDCs and is the agency that maintains the master list of FFRDCs. Over the years FFRDCs have been praised as national treasures, but at times have been the focus of significant criticism. This talk recounts the history of this special class of R&D centers from their beginnings after World War II to their present status.
