1832–1878
An English geologist and naturalist with a taste for adventure, he turned years in goldfields and tropical forests into vivid science writing. He is especially remembered for The Naturalist in Nicaragua and for early observations of the partnership between acacias and ants.

by Thomas Belt
Born in Newcastle upon Tyne in 1832, he grew up with a strong interest in natural history and went on to build an unusually practical scientific career. In the 1850s he worked on the Australian goldfields, later in Nova Scotia, and became known for his knowledge of mining geology and ore deposits.
Travel and fieldwork shaped everything he wrote. Time spent in Nicaragua led to his best-known book, The Naturalist in Nicaragua (1874), a lively blend of travel narrative, geology, and close observation of plants and animals. Readers still remember it for its clear, curious style and for its account of the relationship between bullhorn acacias and the ants that defend them.
He also wrote on glacial geology and wider questions in natural science, bringing together the eye of an engineer and the patience of a field naturalist. Belt died in 1878 in Denver, Colorado, leaving behind a reputation as a careful observer whose books remain engaging well beyond their century.
