Determined to continue the modernization program begun by Wilson, Putnam hired astronomer John Scoville Hall as director in 1958. Hall took advantage of the launch of Sputnik 1 in October 1957 and the ensuing Sputnik crisis in the United States to seek greatly increased federal funding for the Observatory. Putnam used his extensive political connections to help Hall land lucrative federal contracts, which significantly improved the Observatory's finances. Hall also hired energetic, bright young astronomers and rebuilt the Observatory's reputation as a research institution.
