Samuel Horsley (15 September 1733 – 4 October 1806) was a British churchman, bishop of Rochester from 1793. He was also well versed in physics and mathematics, on which he wrote a number of papers and thus was elected a Fellow of the Royal Society in 1767; and secretary in 1773, but, in consequence of a difference with the president (Sir Joseph Banks) he withdrew in 1784.
Life
He was the son of Rev John Horsley of Newington Butts and his first wife Anne Hamilton, daughter of Rev Prof William Hamilton of Edinburgh and Mary Robertson.
Entering Trinity Hall, Cambridge in 1751, he became LL.B. in 1758 without graduating in arts. In the following year he succeeded his father in the living of Newington Butts in Surrey. In 1768 he attended the son and heir of the 3rd Earl of Aylesford to Oxford as private tutor; and, after receiving through the earl and Bishop of London various minor preferments, which by dispensations he combined with his first living, he was installed in 1781 as archdeacon of St Albans.
