R H Kinvig was Professor of Geography, University of Birmingham in mid 1950's - he was I think at one time at Liverpool - as he wrote a paper for Journal Manx Museum in 1936 I suspect he was born c.1910 (or earlier) - he died as far as I can tell in late 70's or early 1980's (the last edition (1978) of his book The Isle of Man: A Social, Cultural and Political History was co-authored)
