Charles Rennie Mackintosh (7 June 1868 – 10 December 1928) was a Scottish architect, designer, water colourist and artist. He, along with painter and glass artist Margaret MacDonald, Frances MacDonald and Herbert MacNair, known as The Four, were prominent members of the The Glasgow School. This was a circle of influential artists and designers that worked in Glasgow, Scotland in the 1870s until about 1920. Glasgow Style designs and art works were created by teachers, students and graduates of The Glasgow School of Art and The Four were at the core of this movement.
