Thank you Peter,
I did spend some time afterwards today reading all of the messages of condolences left by forum members and it is very clear how highly thought of and respected he was as a person and as a researcher. That his posts remain for someone like myself to find is, I think, a great legacy.
My research will continue and I have no doubt, his photographs will play a part. I am trying to get a translation of an article in Romanian at the moment. If I can get that and find out what it says, I might be able to post a new thread tying in his photographs with the article...
