Born Dec. 15, 1870, in Pirnitz (present-day Brtnice, Czechoslovakia); died May 7, 1956, in Vienna. Austrian architect.

Hoffmann studied at the Vienna School of Applied Arts and under K. von Hasenhauer and O. Wagner. He helped organize the Wiener Sezession (1897), the Wiener Werkstätte (1903), and the Österreicher Werkbund (1912). While he was a leading representative of Viennese art nouveau, the rationality of a number of his works paved the way for functionalism.

Hoffmann’s major works include the Purkersdorf Sanatorium near Vienna (1903–04), the Stoclet House in Brussels (1905), and the Austrian pavilions at many exhibitions, including the Deutscher Werkbund Exhibition in Cologne (1914).
