Abraham Rees was born at Llanbrynmair, Monmouthshire (Wales), the son of an independent minister. He died at Finsbury, London on 9 June 1825. He was educated at Coward's Academy in Wellclose Square under David Jennings from 1759, becoming assistant tutor in 1762 and resident tutor on Jennings' death, when the Academy moved to Hoxton, where he remained until 1785. He was then a tutor at Hackney Academy, first in theology and then, from 1790 until the Academy's closure six years later, in mathematics, succeeding Thomas Belsham. He was made DD (Edinburgh) in 1775 and elected FRS in 1786. He became a trustee of Dr Williams' Trust in 1774 and Secretary of the Presbyterian Board in 1778, holding both positions until his death. Meanwhile, after a period as assistant to Philip Furneaux at Clapham, he became, successively, assistant pastor and then pastor at St Thomas's, Southwark, removing in 1783 to the Old Jewry Meeting House, where he remained until his death.
