Victor Horta (1861–1947) was a Belgian architect and a pioneering figure of Art Nouveau. His innovative use of iron, glass, and organic forms helped define the movement, as seen in masterpieces like the Hôtel Tassel, Maison du Peuple, and Hôtel Solvay in Brussels. Horta’s designs emphasized flowing lines, intricate detailing, and seamless integration of decorative arts with architecture. After World War I, he transitioned to Art Deco, adapting to changing trends. Awarded the RIBA Gold Medal (1932), his influence remains strong, with many of his works listed as UNESCO World Heritage sites.
