Charles Rennie Mackintosh (1868-1928), of Glasgow, Scotland, studied at the Glasgow School of Art, and was to become an exponent of Art Nouveau in Scotland and the designer of some of the first modern interiors. His early work is characterized by nature-inspired symbolic decoration, while his later work is characterized by bold geometric patterns. His white and pastel interiors especially, evoked an atmosphere that was the opposite that of his dense and smoky Glasgow.
