Hubert Petschnigg

[1] In 1948 he began working at the architectural firm of Helmut Hentrich and Hans Heuser.

After Heuser's death in 1953, Petschnigg became his replacement and founded the HP firm together with Hentrich.

He was named "Honorary Senator" of TU Graz in 1977, and in 1982 the government of West Germany awarded him the Federal Cross of Merit – a particular honour for Petschnigg, as he was Austrian.

Petschnigg produced his most important works as a partner of the HPP firm that he had founded with Helmut Hentrich.

These included[10] the headquarters of VEBA (now E.ON) in Düsseldorf, the Ministry of the Interior for North Rhine-Westphalia, the RWI Essen research centre, the TÜV Rheinland building in Cologne, the Ruhr University Bochum,[2] and the Europa-Center in Berlin.
