I strongly support this nomination, and hope that it can be approved as soon as possible. Of course, you may say that I am biased, since I had a hand in its preparation, and the location is in my Section (UK&RI).
I did not think that there were significant doubts about Dennis Gabor's education, there is a lot written about it, and the comments by "appyuste" look correct to me.
What I could not find out for sure is whether he was invited to England to work for BTH, or whether he came and then found employment with them. Some of the available descriptions seem to differ over that.
