Francis Graham Moon Chancellor (30 September 1869 – 20 September 1940), styled professionally as F. G. M. Chancellor, was a Tasmanian[1] architect and designer, based in London. He built a reputation as a competent architect, coming to the notice of Frank Matcham, with whom he worked for around 13 years. When Matcham retired in 1913, Chancellor took over the running of Matcham & Co., and successfully transitioned the company from being one that built theatres to constructing modern cinemas. His works include the renovations of The Old Vic in Waterloo, London, between 1922 and 1929; the new Sadler's Wells Theatre in Clerkenwell (1926–31); and a series of super cinemas, the most notable of which being the State Cinema in Grays, Essex, which opened in 1938.
Chancellor retired shortly before 1939 and died at his Buckinghamshire home in 1940.
