My very good friend Ray Mansfield sadly passed away on 6 March 2016. He was a well known caver in his younger days, and will probably be best remembered for his bibliographic work, especially BCRA's bibliographic index Current Titles in Speleology. He had an amazing memory and was able to recall facts at a moment's notice.
I'm not in the right frame of mind to write more at the moment, but see some comments on the UK cavers forum.
