Gustav Klimt (1862–1918) was an Austrian Symbolist painter and one of the most prominent members of the Vienna Art Nouveau movement. His major works include paintings, murals, sketches and other art objects, many of which are on display in the Vienna Secession gallery. Klimt's primary subject is the female body, and his works are marked by a frank eroticism. (source)
