After the war, the property was returned to the Reinhardt estate. In 1946 Helene Thimig, the widow of Max Reinhardt, offered use of the palace to Clemens Heller, who founded the Salzburg Seminar in American Studies, a "Marshall Plan of the Mind," together with Scott Elledge and Richard Campbell, all Harvard graduate students. The Salzburg Seminar brought together young people from the countries that had been in conflict during World War 2 and originally offered education on American history, art, literature, and culture, in a period when United States armed forces occupied parts of Germany and Austria. This was later transformed into a "global forum". Since 1947, more than 500 sessions of the Seminars have been held on a wide variety of issues.
