Charles Richter filed for a patent for his electric lamp improvements in March of 1915 and was granted Patent Number 163252 in June, 2015. Richter was an electrical worker from the Corporation of the District of Fraser Mills, a small municipality on the shores of the Fraser River that would later be amalgamated with the District of Coquitlam, B.C.
Richter’s invention was designed to provide “a simple, inexpensive and effective reflector…that will disperse the light from a group of incandescent lamps over a wide area.” (Source: Patent Number 163252, Library and Archives Canada, http://www.bac-lac.gc.ca/eng/discover/patents-1869-1919/Pages/item.aspx?…). His invention helped to improve the usefulness of incandescent lights indoors by increasing the area covered by a single lamp.
