It is our aim to have a picture of everyone represented in this Who's Who. We have tracked down many illustrations, some of them rare, and correspondents have helpfully provided us with more. But many gaps remain to be filled. Can anyone out there help us with photographs of any of the following? (Please note that we aim to respect copyright in all cases):
