Richard Knill Freeman was a British architect who began his career at Derby and moved to Bolton, Lancashire in the late 1860s. His work, in Victorian Gothic style and typically recalling the Decorated Period of later medieval architecture, can be seen in several cities and towns across the north of England. He worked in total on about 140 buildings, of which about half survive in some form.
