Henry M. Cadell

Henry Moubray Cadell of Grange, DL FRSE LLD (1860 – 10 April 1934) was a Scottish geologist and geographer, noted for his work on the Moine Thrust, the oil-shale fields of West Lothian, and his experiments in mountain building published in 1888. He also travelled extensively abroad, for example in 1899 he travelled the length of the Irrawaddy River in Burma. He is especially remembered for his working models, explaining geomorphology, the science relating to the folding of rock beds. He was also a competent amateur artist. .

Life He was born in Scotland in 1860. He was the eldest of seven children to Henry Cadell of Grange by his second wife, Jessie Gray MacFarlane. His father was a mining industrialist with considerable lands and company interests in Linlithgowshire and Stirlingshire. He was raised at the family home of Grange House (built 1564) near Bo'ness.

He was educated at the University of Edinburgh (studying geology under Archibald Geikie from 1878 to 1881) and then spent a further year studying at the Clausthal Royal Mining Academy in Germany, before entering the employment of the Geological Survey of Scotland. He worked with the Survey from 1883 to 1888, largely surveying in the Scottish Highlands, then abandoned this to instead manage his family's estates (which included several large collieries), following the death of his father in January 1888.

His work with the Survey included geological investigations around Loch Eriboll in north-west Sutherland. This investigation was partly aimed to resolve a geological quandary raised by Charles Lapworth, which puzzled over the inter-relationship between metamorphosed Moine rocks and non-metamorphosed Cambrian rocks beneath. This led Cadell to speculate that the rocks had been folded over on themselves. He conducted many experiments to support his theories (which are now proven to be fully correct). They had seven daughters and one son.

His great uncle was the mineralogist Thomas Edington FRSE.
