BERLIN— After 37 years of running his eponymous gallery, the noted New York dealer Achim Moeller is expanding — but keeping it in the family. His daughter Stephanie Rita Moeller, 29, has just opened a branch of Moeller Fine Art in Berlin. The 4,000-square-foot space is located in a landmarked 19th-century building beside the Landwehr Canal, in the art district of Kreuzberg.

Like the New York branch, the Berlin one will show both modern and contemporary art. On display until June 20 is a group show juxtaposing the work of masters like Marcel Duchamp and Paul Klee (€50,000-2.5 million; $65,000-3.2 million) with new multimedia pieces by such artists as Matthias Düwel and Hubertus Gojowczyk (€5,000-150,000; $6,500-19,000). A concurrent exhibition showcases fairy-tale drawings, comic strips and wooden figures by Lyonel Feininger, whose three-part catalogue raisonné Moeller père began publishing in 2006.

Born in Heidelberg, Moeller began his career at New York’s Wildenstein & Co. in the 1960s. In 1972, after four years with Marlborough-Gerson — where he first worked with the Feininger estate — he opened a gallery in London. In 1982 he moved back to New York and opened his own gallery there in 1984. His daughter did a stint at the New York photography gallery Bonni Benrubi before moving in 2003 to Berlin, where she managed the holdings of the collector Hans-Joachim Sander.

For his part, Moeller picked Berlin because "30 percent of our clients are in the German-speaking countries. Berlin may not have the infrastructure of collectors, but there is lots of energy, and it’s the center of contemporary art."
