Frederick Murray Trotter

Frederick Murray Trotter (19 April 1897 – 24 July 1968) was a British geologist, who worked for his whole career with the British Geological Survey. He became best known for his geological field studies of industrial minerals – coal, salt and iron ores – and was awarded the Murchison Medal of the Geological Society of London in 1956.

Life and works

Trotter was born in Gateshead, and grew up in Durham and Newcastle. He was educated at Rutherford College of Technology, and then went to Armstrong College, Newcastle, to study chemistry and geology. During the First World War, from 1916 to 1918 Trotter served as a corporal with the Royal Engineers corps of signals as a despatch rider. In 1918, he was hit by shrapnel while on duty near Vimy in France. This caused him to lose one eye and a part of his skull. and their joint monograph on Brampton was published in 1932. Trotter worked for the survey for the rest of his career, and by the time he retired in 1963, he had reached the position of assistant director (England and Wales). During his career he worked first on the glacial deposits of the Eden valley, and later on the coal fields of South Wales and Lancashire; the salt fields of Cheshire, and hematite ore mineralisation of Cumbria.

Awards Trotter received the Lyell Fund in 1938 for his geological researches on the glacial and post-glacial phenomena of the Eden Valley. In 1956, he was awarded the Murchison Medal from the Geological Society of London, and in 1967 he was awarded the Sorby Medal of the Yorkshire Geological Society.
