Christopher Hutton
Christopher William Clayton Hutton (1893–1965) a soldier, airman, journalist and inventor, was recruited as an intelligence officer to work for MI9, a branch of the British Military Intelligence, during the Second World War. Known as 'Clutty' to his friends, he was engaged towards the end of 1939 by the War Office to work under Major (later Brigadier) Norman Crockatt, in order to set up and run operations to create and distribute escape and evasion aids for Allied servicemen. Hutton's small team identified suitable manufacturers, ensured supplies and devised methods by which the concealed aids could be sent to prisoner of war camps.
James Hutton
He had a house built in 1770 at St John's Hill, Edinburgh, overlooking Salisbury Crags. This later became the Balfour family home and, in 1840, the birthplace of the psychiatrist James Crichton-Browne. Hutton was one of the most influential participants in the Scottish Enlightenment, and fell in with numerous first-class minds in the sciences including mathematician John Playfair, philosopher David Hume and economist Adam Smith. Hutton held no position in the University of Edinburgh and communicated his scientific findings through the Royal Society of Edinburgh. He was particularly friendly with physician and chemist Joseph Black, and together with Adam Smith they founded the "Oyster Club" for weekly meetings.
