Bischofberger opened his first gallery in 1963 on Pelikanstrasse in Zurich, then under the name City-Galerie. In 1965, he hosted his first exhibition of Pop Art at the gallery with works by Roy Lichtenstein, Robert Rauschenberg, Andy Warhol, Tom Wesselmann, Claes Oldenburg and Jasper Johns. In the 1970s, Bischofberger continued to showcase American Pop Art along with proponents of Minimalism, Land Art and Conceptual Art, such as Sol Le Witt, Donald Judd, Dan Flavin, Bruce Nauman, Joseph Kosuth and On Kawara, and representatives of Nouveau Réalisme in Paris, such as Yves Klein, Daniel Spoerri and Jean Tinguely. Between 1982 and 2005, a three-volume catalogue raisonné of Jean Tinguely’s oeuvre was published by Bischofberger’s wife Christina. In the 1980s, Bischofberger championed key figures of the nascent Neo-Expressionist movements, such as Miquel Barceló, Jean-Michel Basquiat, Mike Bidlo, George Condo, Francesco Clemente, Enzo Cucchi, Dokoupil, Peter Halley, David Salle and Julian Schnabel.
