Aufbau (German for "building up, construction") is a periodical targeted at German-speaking Jews around the globe. Founded in 1934 in New York City as a newspaper for German Jewish immigrants, it was reinvented in 2004 in Switzerland as a glossy magazine for German-speaking Jews of the 21st century. Hannah Arendt, Albert Einstein, Thomas Mann, and Stefan Zweig wrote for the original publication. Until 2004 it was published in New York City. It is now published in Zürich.
