An Austrian painter, designer, and key member of the Vienna Secession, Koloman Moser was a driving force behind the integration of fine and applied arts in early modern design. A co-founder of the Wiener Werkstätte, he created elegant, geometric patterns and decorative objects that united craftsmanship with simplicity and function. His work spanned painting, furniture, textiles, and graphic design, helping to define the distinctive visual language of Viennese Art Nouveau and laying the groundwork for modern design principles.
