# Thomas Davidson (palaeontologist)

Thomas Davidson (17 May 1817 – 14 October 1885) was a British palaeontologist.

## Biography

He was born in Edinburgh. His parents possessed considerable landed property in Midlothian. Educated partly in the University of Edinburgh and partly in France, Italy and Switzerland, and early acquiring an interest in natural history, he benefited greatly by acquaintance with foreign languages and literature, and with men of science in different countries.
He was induced in 1837, through the influence of Leopold von Buch, to devote his special attention to the brachiopoda, and in course of time he became the highest authority on this group. The great task of his life was the Monograph of British Fossil Brachiopoda, published by the Palaeontographical Society (1850–1886). This work, with supplements, comprises six quarto volumes with more than 200 plates drawn on stone by the author. He also prepared an exhaustive memoir on Recent Brachiopoda, published by the Linnean Society. He monographed the entire series of Brachiopoda collected by HMS Challenger.
Davidson benefited from an introduction to Elizabeth Gray by John Young in 1865. Gray had a lifelong interest in the fossils of Girvan in Scotland. Her family took their holidays there each year and they would devote their time to gathering cleaning and labelling fossils. Gray had some basic geology training, but she preferred to let others do the scientific descriptions. Gray would send collections of fossils, including brachiopoda, regularly over several years between 1867 and 1885. Davidson also worked closely with British paleontologist Agnes Crane, who completed the editing work on Davidson's final, posthumous, Monograph of Recent Brachiopoda.
He was elected fellow of the Geological Society of London in 1852 and in 1865 awarded their Wollaston medal. He was elected Fellow of the Royal Society in 1857, and in 1870 received a Royal medal from the Royal Society. In 1882, the degree of LL.D. was conferred upon him by the University of St Andrews. In 1866, he was elected as a member to the American Philosophical Society.
Davidson died at Brighton on 14 October 1885, bequeathing his fine collection of recent and fossil brachiopoda to the British Museum. He was buried in the churchyard of St Peter's Church, Twineham. (His son, William Davidson, had inherited Hickstead Place and the Manor of Twineham through his wife, the daughter of John Wood, of Hickstead Place.)
