(Born: North Cray, Kent, England, 11 July 1795; Died: London, England, 16 September 1857) English geologist & mineralogist.

Trimmer studied under William Davison, curate of New Brentford. In 1814, he was sent to manage his father's copper mine in North Wales. He was appointed overseer of the slate quarries near Bangor and Carnarvon, Wales in 1825. Trimmer took in 1840 a position with the Geological Survey of England. He discovered sands with marine fossils of existing species 1,350 ft. above sea level and did work to classify mineral desposits. He was elected a Fellow of the Geological Society.
