Koloman Moser (1868 – 1918) was an Austrian artist who exerted considerable influence on twentieth-century graphic art. He was one of the foremost artists of the Vienna Secession movement and a co-founder of Wiener Werkstätte. Moser designed a wide array of artworks, including books and graphic works from postage stamps to magazine vignettes; fashion; stained glass windows, porcelains and ceramics, blown glass, tableware, silver, jewelry, and furniture.

Moser studied at the Wiener Akademie and the Kunstgewerbeschule, where he also taught from 1899. His designs in architecture, furniture, jewelry, graphics, and tapestries helped characterize the work of this era. He drew upon the clean lines and repetitive motifs of classical Greek and Roman art and architecture in reaction to the Baroque decadence of his turn-of-the-century Viennese surroundings. In 1905, together with the Klimt group, he separated from the Vienna Secession.

Moser was one of the designers for Austria’s leading art journal Ver Sacrum. This art journal paid great attention to design and was designed mainly by Moser, Gustav Klimt, and Josef Hoffmann.
