In reply to Doug:
Well he was at Manchester University so I'm pretty certain it was he. Also wrote caving books. I think he was a member of the University climbing club at the time. I'm sure I have read some of his articles. Incredible varied life.
He had a shed at the bottom of his garden where he could tinker to satisfy his inquiring mind. Also worked at NASA in the early days before his Gaia hypothesis was published.
