Samuel James Shand: Difference between revisions

Samuel James Shand FRSE (1882–1957) was a British mineralogist and petrologist, specializing in silicate analysis and igneous petrology.^[1]

Shand received his secondary education at George Watson's College, Edinburgh, and then in 1905 received his B.Sc. in science from University College, Dundee, which from 1897 to 1967 was part of the University of St Andrews. He then became a graduate student at the University of Münster and received a Ph.D. (Promotion) there in 1906 with thesis advisor Karl Busz [de].^[2] Upon Shand's return to Scotland, he became an assistant curator in charge of the geological collections at the Royal Scottish Museum in Edinburgh from 1907 to 1911. He received a D.Sc. from the University of St Andrews in 1910.^[1]

Shand became in 1911 professor of geology and mineralogy at Victoria College, Stellenbosch (which was renamed Stellenbosch University in 1918). During WWI he served in the Royal Engineers as a lieutenant, helping to find water resources for the British army in the Middle East.^[1]

Shand established the geology department of Stellenbosch University and published approximately 30 papers on various aspects of the geology and mineralogy of southern Africa. In 1914 he presented fossils from the Bokkeveld Group and a collection of rocks to the McGregor Museum in Kimberley.^[1] Shand discovered, among rock specimens sent to him by P. H. S. de Wet in 1913, the mineral pseudotachylyte, which, in 1916, Shand was the first to scientifically describe.^[3]

His classification of eruptive rocks was based mainly on the extent to which the rocks were saturated with silica, their mineralogical composition and texture. The classification was later developed further in his book Eruptive rocks; their genesis, composition, classification, and their relation to ore deposits (London, 1927; 4th ed. 1951), which ensured his international reputation. According to Scholtz (1946) his classification of eruptive rocks and studies of the petrology of South African alkaline rocks constitute one of the most fundamental contributions made by members of the Geological Society of South Africa during its first 50 years.^[1]

Shand resigned in 1937 from Stellenbosch University to become a professor of petrology at Columbia University, remaining there until his retirement in 1950 when he returned to Scotland.^[1] In retirement he helped to reorganize some of the same museum collections in Edinburgh that he worked on forty years earlier.^[2]

Shand was elected a fellow of the Royal Society of Edinburgh, the Mineralogical Society of Great Britain and Ireland, and the Geological Society of London, which awarded him in 1950 its Lyell Medal. He was for the year 1923 the president of the Geological Society of South Africa, which awarded him in 1937 its Draper Memorial Medal.^[1] The mineral shandite, a lead-nickel-sulfide occurring in the serpentine subgroup, was discovered and named in his honour by Paul Ramdohr in 1950.
