text: An Extraordinary General Meeting was held on 27 March 1906, under the direction of president Edward Divers and secretary C. G. Cresswell, to discuss a motion to apply for incorporation under a royal charter. The resolution was formally proposed by Sir (Thomas) Boverton Redwood. After some discussion, the motion was unanimously supported.
  The society was formally incorporated, by Royal Charter, as of 17 June 1907, and its bylaws were published in the Journal of the Society of Chemical Industry. By that time, it had expanded to include a number of satellite chapters, including Canada, New South Wales, New York and New England as well as locations within Great Britain.
