Augustus Matthiessen


Augustus Matthiessen, FRS, the son of a merchant, was a British chemist and physicist who obtained his PhD in Germany at the University of Gießen in 1852 with Johann Heinrich Buff. He then worked with Robert Bunsen at the University of Heidelberg from 1853 to 1856. His work in this period included the isolation of calcium and strontium in their pure states. He then returned to London and studied with August Wilhelm von Hofmann from 1857 at the Royal College of Chemistry, and set up his own research laboratory at 1 Torrington Place, Russell Square, London. He was elected a Fellow of the Royal Society in 1861. He worked as a lecturer on chemistry at St Mary's Hospital, London, from 1862 to 1868, and then at St Bartholomew's Hospital, London, from 1868. His research was chiefly on the constitution of alloys and opium alkaloids. He contributed to both physics and chemistry. For his work on metals and alloys, he was awarded the Royal Society's Royal Medal in 1869.
Matthiessen committed suicide in 1870 under "severe nervous strain".

Legacy

The Matthiessen's rule for carrier mobility probably originated from Augustus Matthiessen's study of electrical conduction of metals and alloys.
In 1997, Rudolf de Bruyn Ouboter briefly mentioned Matthiessen's 1864 paper in a figure inside his article about Heike Kamerlingh Onnes's discovery of superconductivity.
