As a painter, as well as a teacher, the Russian-born artist Wassily Kandinsky has paid a major role in the development of modern art. In-depth influenced by music - "music is the ultimate teacher" - Kandinsky paints his first abstract compositions during his Bavarian period (1906-1914), and his intensely use of color and form has influenced successive abstract artists from his own time to the present day. Inspired, in a first time, by Theosophical theory - which postulates that creation is a geometrical progression, beginning with a single point - Kandinsky was one of the co-founders of the "Blaue Reiler" movement (1911) and instructor at the Bauhaus for eleven years, in which time he published "Point and Line to Plane" (1926), his second book with clear echoes of basic Theosophical tenet.
