Henry Clarke (1743–1818) was an English mathematician, a significant teacher in north-west England, and mathematical writer and translator.
[4] After a brief partnership with Robert Pulman, a schoolmaster at Sedbergh, he travelled in Europe, and returned to settle as a land surveyor in Manchester.
[4] While the school was not a success in financial terms, Clarke trained future mathematicians, such as Hugh Byrom and Thomas Molineux, and contributors to mathematical periodicals, including the Ladies' Diary.
[4] A member of the Manchester Literary and Philosophical Society, in 1783 Clarke became lecturer in mathematics and experimental philosophy in its "College of Arts and Sciences", which only lasted a few years.
He was in that year appointed professor of history, geography, and experimental philosophy at the Royal Military College at Great Marlow, which moved in 1812 to Sandhurst, Berkshire.
