Robert Were Fox the Younger



Robert Were Fox FRS (April 26, 1789 – July 25, 1877), English geologist and natural philosopher, known today mainly for his work on the temperature of the earth and his construction of a compass to measure magnetic dip at sea. He was a member of the Religious Society of Friends (Quakers), and was descended from members who had long settled in Cornwall, although he was not related to George Fox who had introduced the community into the county.[1]

Life and family

Fox was born in 1789 at Falmouth, the son of Robert Were Fox (1754 - 1818)[2] and his wife, Elizabeth Tregelles. In 1814, Fox the Younger married Maria Barclay (1785 – 1858), daughter of Robert and Rachel Barclay of Bury Hill, near Dorking, Surrey. Her sister, Lucy, married Fox's elder brother, George Croker Fox.[3] Robert Were Fox the Younger and his wife had three children, Anna Maria (1816 – 1897), Barclay (1817 – 1855) and Caroline (1819 – 1871).[4] Caroline became a noted diarist.[5]

Fox was involved in many aspects of his family's businesses, along with his many brothers. He also served as Honorary Consul of the U.S.A in Falmouth from 1819 to 1854.

Fox's gardens at Rosehill[6] and Penjerrick, near Falmouth, became noted for the number of exotic plants which he and his son, Barclay, had naturalized.

Robert Were Fox the Younger died on July 25, 1877 and was buried at the Quaker Burial Ground at Budock.

Scientific work

  Fox's work was in what today would be referred to as geophysics. He was distinguished for his researches on the internal temperature of the earth, contributing papers to the Royal Geological Society of Cornwall,[8] and being the first to prove that temperature definitely increases with depth (the geothermal gradient), his observations being conducted in Cornish mines from 1815 for a period of forty years.[9] In 1829 he began a set of experiments on the artificial production of miniature metalliferous veins by means of the long-continued influence of electric currents, and his main results were published in 1836.[10]

In 1834 Fox constructed an improved form of deflector dipping needle compass, or dip circle, for polar navigation.[11] One was used by Sir James Clark Ross on his Antarctic expedition and used to discover the position of the South magnetic pole.[12]

Robert Were Fox, his cousin, George Croker Fox (1784-1850) and brother, Alfred Fox, assembled excellent collections of minerals, which are now in the British Museum (Natural History), given by Arthur Russell.[13]

Honours and activities

  • Fellow of the Royal Society (Elected September 9, 1848)[14]
The Society owns a collection of 125 letters addressed to Fox and his family.[15]
  • Fox was an active member of the British Association for the Advancement of Science in its early days.
  • Fox was a founder, in 1833, of the Royal Cornwall Polytechnic Society.
