At the beginning of the twentieth century, when poster designer, Art Nouveau book illustrator, designer, photographer, and painter Alfons Mucha traveled to the United States to take up a teaching position, he was greeted with great enthusiasm. One of the most important representatives of Jugendstil, Mucha attracted a wide audience by moving among genres more skillfully than virtually any other artist of his day. After training as a stage decorator in Vienna, Mucha moved to Paris, where, in the 1890s, he created a stir with his stylistically refined and elegantly executed posters. Mucha’s designs represented not merely a personal artistic breakthrough; they also revolutionized the aesthetics of what was still a new medium. In his later works, he developed the inimitable “Mucha style,” which celebrated floral elements, lines, and beauty. This book traces the trajectory of Mucha’s career, offering brilliant reproductions of his work in various media that showcase his innovative designs.
