Works by Ernst Ludwig Kirchner and Henri Matisse were added to the collection at the end of the 1940s and 1950s. During this time, the Stedelijk also acquired artworks by De Stijl and related international movements such as Russian Constructivism and Bauhaus. Edy de Wilde, who had run the Van Abbe Museum in Eindhoven, took over as director from 1963 to 1985. He began the first collection of American contemporary art at the Stedelijk. Under his direction, in 1971, debates about the museum's social and educational functions sparked the formation of a communications department. In the early 1970s, the museum made its first acquisitions of video art by European artists including Dibbets and Gilbert & George. Today, the collection of video art contains around 900 works and installations, including works by Nam June Paik, Bill Viola and Bruce Nauman. By the mid-1970s, after the last period rooms were closed, the Stedelijk became exclusively a museum for modern art. 21st century In 2001, drawings by Kazimir Malevich and other Russian avant-garde artists from the collection of the Khardzhiev-Chaga Cultural Centre were added to the museum's collection of Ukrainian / Russian / Soviet art. At the end of 2003, the Adriaan Willem Weissman building was closed at the insistence of the fire department; renovation work began. The Stedelijk took up temporary residence in the Post CS Building, where it would remain for 4.5 years. In 2005, the museum established a partnership with The Broere Charitable Foundation; on behalf of the Monique Zajfen Collection, the museum acquired contemporary European artworks, which were placed at the museum on long-term loan. In 2006, debates and lectures were organized in the context of the exhibition 'Mapping the City', which explored the relationship of artists to the city. Space was created called the 'Docking Station' for monthly presentations of work by emerging artists. In 2008, 'Other voices, other rooms', an exhibition highlighting the video work of Andy Warhol, drew 600,000 visitors. In 2006, the city council privatized the Stedelijk. It became a more businesslike enterprise that leases the museum building from the city and, on behalf of the council, mounts exhibitions and manages, maintains, and adds to the municipal collection. Starting in late 2008, the Stedelijk underwent major construction. In response to this, the museum started the "Stedelijk goes to Town" project
