Smyth was born at
Naples, the son of
Admiral W H Smyth and his wife Annarella Warington. His father was engaged in the Admiralty Survey of the
Mediterranean at the time of his birth. Smyth was educated at
Westminster School and
Bedford School. He then went to
Trinity College, Cambridge, where he was a member of the
Cambridge crew in the
1839 Boat Race and graduated
BA in 1839. Having gained a travelling scholarship he spent more than four years in
Europe,
Asia Minor,
Syria and
Egypt, paying great attention to
mineralogy and
mining, examining coal-fields, metalliferous mines and salt-works, and making acquaintance with many distinguished geologists and mineralogists. Smyth married Anna Maria Antonia Maskelyne, daughter of Anthony Mervin Story Maskelyne, of Basset Down House, Wiltshire on 9 April 1864. One son,
Herbert Warington Smyth, was also a mining engineer, a
traveller, and a Geological Survey adviser to the government of
Siam. Another son,
Sir Nevill Maskelyne Smyth (1868–1941), won the
Victoria Cross at the
Battle of Omdurman. Smyth died in his
London home in Inverness Terrace,
Bayswater, on 19 June 1890, but was buried at
St Erth, not far from his country home, Cliff Cottage at
Marazion in
Cornwall. He is commemorated by a wall plaque in
Truro Cathedral, where he had been a founding member of the building committee responsible for its construction. ==Geological Survey==
