The German lyric baritone, Walter Hauck, completed his high school diploma at the Oberrealschule Ludwigshafen. He then began studying at the Technischen Hochschule Darmstadt (Darmstadt Technical University) before taking up a music degree at the Hochschule für Musik in Berlin for four years, where he was a student of Julius von Raatz-Brockmann. Further education in singing followed in 1938-1939 with Emmi Leisner and in 1940-1941 at the Berliner Opernschule Klindworth-Scharwenka. Already during his training he appeared since 1925 as a concert singer.
In 1941 Walter Hauck accepted a stage engagements at the Stadttheater of Cottbus, whose member he remained he until 1944. His debut role there was Count Luna in Giuseppe Verdi's Il trovatore. Other singing roles during this time were the title role in W.A. Mozart's Don Giovanni, Flut in Otto Nicolai's Lustigen Weiber von Windsor and Dr. Malatesta in Don Pasquale.After World War II, he made a major shift and focused nearly completely on his concert career and could be found on the stage only occasionally at the Städtischen Oper Berlin. In the concert hall he was estimated primarily for his art of J.S. Bach interpretation, but he dedicated himself also to the contemporary music work. In 1953 he sang at the Festival of Venice Ode an Napoleon by Arnold Schoenberg.
