Following a career which included two years with gallery owner Barbara Gladstone in New York, Martin Klosterfelde founded the eponymous gallery in Berlin in 1996. It focused on pioneering new artists as well as more established names. Exhibitions there included solo shows for artists who now enjoy international acclaim including Hanne Darboven, Matt Mullican, John Bock, Christian Jankowski, Elmgreen & Dragset, Danh Võ, and Lawrence Weiner. In addition, the gallery was a regular and frequent participant in renowned art fairs such as Art Basel, FIAC, Frieze, Art Basel Miami Beach, Independent and The Armory Show. In the summer of 2013, after 18 years and 104 exhibitions, Martin closed his gallery and became Director and International Art Specialist at Phillips, based in Berlin. In 2016, he trained as an auctioneer. In September 2016 Martin joined Sotheby’s as Senior Director and Senior Specialist, bringing the Contemporary Art team in London the benefit of his extensive knowledge and experience in the acquisition of works of contemporary art.
