[Jewish urologists in Hamburg: eight biographies from Imperial Germany to Nazi Germany].

Before the Nazis seized power in 1933, eight Jewish urologists practiced in the city of Hamburg: Otto Einzig, Moritz Fürst, Ernst Fränkel, Wilhelm Haas, Friedrich Lührse, Paul Rosenberg, Sigmund Wertheim and Erich Wohlauer. This contribution traces their lives and careers. One of them was murdered at the Theresienstadt concentration camp and seven emigrated to the USA, Sweden and South Africa. One emigrant committed suicide shortly after arriving in the USA and while the other six continued to practice medicine, they did so under precarious conditions.
