Sachs' extensive art collection included works by Jean Fautrier, Andy Warhol, René Magritte, Salvador Dalí, Roy Lichtenstein, Tom Wesselmann, Mel Ramos, and Allen Jones. He also owned important pieces from the Nouveau réalisme school including Yves Klein, Jean Tinguely, Arman, and Martial Raysse. Many of these artists were involved in the 1969 design of the legendary pop-art-apartment in the tower of the Palace Hotel in St. Moritz, which quickly gained the art world's attention. From 1967 to 1975 Sachs, together with Prince Konstantin of Bavaria, co-founded and headed the association for the Modern Art Museum in Munich (MAM), which lobbied for the construction of a comprehensive museum of contemporary art in Munich and mounted monthly exhibitions at Villa Stuck. Victor Vasarely, Georg Baselitz, Heinz Edelmann, Christo, Cy Twombly, Alexander Calder, Heinz Mack and Jean Tinguely, Roy Lichtenstein, and Gotthard Graubner found their way into the rooms of the museum.
