==Honours== 
 Noticing no date was given to his becoming a Fellow of the Royal Society, I have added a section on honours he received - mostly degrees and freedoms - which may be of interest given his mixed reputation and that he refused knighthood, cited to Kelly's Handbook and the Dictionary of National Biography (1931-1940). Surprising may be that he was made in 1939 an honorary Air Commodore in the Auxiliary Air Force!  I have left the awards undated where I found no date given in my sources.
