Hugh Marshall

Professor Hugh Marshall FRS FRSE FCS (7 January 1868-5 September 1913) was a Scottish chemist who discovered persulphates in 1891.[1] He was the inventor of Marshall's acid.[2] In 1902 he proposed the modified sign of equality which became standard in chemistry to represent dynamic equilibrium[3].

Marshall's Acid

Life

He was born in Edinburgh on 7 January 1868 and educated at Moray House Normal School. He studied science at the University of Edinburgh and graduated with a BSc in 1886 and gained a doctorate (DSc) in 1888.

In 1894 he began lecturing in mineralogy and crystallography at the University of Edinburgh, changing to chemistry in 1902 and moving to Dundee University College (which was later to become the University of Dundee but was then a constituent college of the University of St Andrews) as Professor of Chemistry in 1908.

In 1888 he was elected a Fellow of the Royal Society of Edinburgh. His proposers were Alexander Crum Brown, Leonard Dobbin, John M. MacFarlane, and John Chemist. He won the Society's Keith Prize for the period 1899-1901. He was elected a Fellow of the Royal Society of London in 1904.[4]

He died in London on 5 September 1913 aged 45. He did not marry and had no children.

gollark: Even if we do end up actually switching stuff over to them in the next N years, there will be *so many* devices which don't get updated.
gollark: While there are quantum-cryptography-proof cryptographic schemes around, they're barely in the early stages of being standardized, not really deployed in any common protocols yet, not reviewed as thoroughly as existing primitives, and generally not very production-ready.
gollark: Which allows factoring things faster, and also apparently discrete logarithm problems somehow.
