Peter Blum has collaborated with a wide range of artists both as a gallerist and publisher since he began his career in 1971 at Galerie Beyeler in Basel, Switzerland. In 1980, after moving to New York, he founded Peter Blum Edition, where he was among the first print publishers to work with a new generation of European and American artists. Peter Blum Edition has since published important editions by Louise Bourgeois, James Turrell, Barbara Kruger, John Baldessari, Brice Marden, Eric Fischl, Josef-Felix Müller, Luc Tuymans, Sherrie Levine, Alex Katz, Tacita Dean, and Alfredo Jaar, among many others.

In 1984, Blum co-founded PARKETT magazine, working directly with international artists and critics to create an engaging forum for contemporary art. In 1993, he opened Peter Blum Gallery at 99 Wooster Street, New York. Over the years this space has hosted important exhibitions- both of recent works and also historical surveys- featuring works by artists such as Robert Ryman, Alex Katz, Louise Bourgeois, Yayoi Kusama, Agnes Martin, David Rabinowitch, Suzan Frecon, Philip Taaffe, Amar Kanwar, Kimsooja, Francesco Clemente, Kazimir Malevich, Piet Mondrian, Ad Reinhardt, Antoine Pevsner, Ian Wilson, Albert Steiner, Helmut Federle, Alberto and Augusto Giacometti, Alighiero e Boetti, Richard Long, and Agnes Martin.

In 2006, Peter Blum opened an additional 3,000 square foot exhibition space in the Chelsea neighborhood of New York, located at 526 West 29 Street. Exhibitions at Peter Blum Chelsea have included works by Chris Marker, Su-Mei Tse, Adrian Paci, John Beech, Rosy Keyser, Robert Zandvliet and Rudolf de Crignis, among others.

The Peter Blum Edition Archive (1980-1994) was the subject of the exhibition Singular Multiples at the Museum of Fine Arts, Houston in 2006, the largest exhibition ever in North America devoted entirely to printmaking. In 2007, a selection of the Peter Blum Edition portfolios formed the exhibition Scenes and Sequences at the Aargauer Kunsthaus in Aarau, Switzerland.

As a member of the Art Dealers Association of America (ADAA), Peter Blum Gallery subscribes to the highest standard of connoisseurship, scholarship and ethical practice, and offers an effective and confidential alternative for the resale of important works of art from and on behalf of private individuals and institutions.
