 Following the gift of approximately 80 works to the Solomon R. Guggenheim Foundation by Hannelore and Rudolph Schulhof (a former trustee of the foundation) in 2012, some works collected by Guggenheim were removed from the Palazzo to make room for the display of the new works.The Schulhofs' names were inscribed alongside Guggenheim's at both entrances of the museum.Their son, Michael P. Schulhof, has been a trustee of the Guggenheim foundation since 2009.
