Emil Hoppe was an architect, textile designer, and decorative and graphic artist. He attended the Staatsgewerbeschule (State Trade School) in Vienna and then studied at the Akademie der bildenden Künste (Academy of Fine Arts) under Otto Wagner between 1898 and 1901. In 1901, he was awarded the Schwendenwein Stipend, which enabled him to travel to Italy. There he produced topographic sketches and a number of drawings of visionary architecture. From 1902 to 1909 he was employed in Wagner's office along with fellow Wagner students Marcel Kammerer and Otto Schönthal. Hoppe was involved with major projects, including the 1906 Austrian Post Office Savings Bank and the Church am Steinhof, built between 1905 and 1907. After 1909, Hoppe, Kammerer, and Schönthal joined together to form their own architectual practice, working on projects in Vienna and abroad. One of Hoppe's most important architectural commissions from this time was the interior of the Austrian pavilion at the 1911 Exposizione Internazionale d'Arte (International Art Exhibition) in Rome. After World War I, Hoppe and Schönthal continued in practice together.
For the Wiener Werkstätte, Hoppe designed postcards in conjunction with the 1908 Kunstschau Wien (1908 Art Show Vienna). He also designed cards depicting Vienna and other places in the Austro-Hungarian Empire. In addition to his work as an architect and designer, Hoppe was active with other firms, creating textile designs for Johann Backhausen & Söhne and glassware designs for E. Bakalowits & Söhne, Vienna.
