1970s and 1980s
Peggy Guggenheim transfers ownership of her collection to the Solomon R. Guggenheim Foundation with the understanding that the works of art will remain in Venice. She dies in 1979, and the foundation takes ownership of the palazzo. Thomas M. Messer is appointed director of the Peggy Guggenheim Collection in addition to his role overseeing the New York museum. He also supervises a major effort to conserve and document the Venice holdings. In 1980, Messer is named director of the Solomon R. Guggenheim Foundation.
Thomas Krens succeeds Messer as director of the Foundation. Krens takes charge of an expansion program already underway in New York, which will include a tower designed by Gwathmey Siegel & Associates Architects, and initiates planning for a comprehensive restoration of the Wright building.
