Austrian architect. Wagner encountered the work of Karl Friedrich Schinkel while studying in Berlin, and his work in Vienna illustrates the importance of classicism to Viennese Art Nouveau. In 1894 he was commissioned to design stations for the city, and in 1898 his two apartment blocks at 38 and 40 Linke Wienzeile were among the earliest examples of Jugendstil architecture in Vienna. Wagner joined the Secession in 1899, allying himself with the younger radical artists. His Post Office Savings Bank (begun 1903) exemplifies his modern classicism.
