Charles Rennie Mackintosh was a Scottish architect, designer, artist, and water colorist. He was a prominent figure of several major European arts movements, such as Symbolism, Art Nouveau, Arts and Crafts, and the Glasgow Style. He began as an apprentice to John Hutchinson and attended part-time classes at the ‘Glasgow School of Art.’ He then joined the firm ‘Honeyman and Keppie,’ where he became a partner later. He was known for his collaboration with Herbert MacNair and the Macdonald sisters, Margaret and Frances, and they later became famous as “The Four.” He married Margaret later. He is remembered for his designs of the ‘Glasgow School of Art’ and the tearooms of Kate Cranston. In his later years, he suffered from oral cancer. He died of the disease in 1928.
