Isaac Townsend

Isaac Townsend (c.1685 – 21 November 1765) was an admiral in the British Royal Navy and a Member of Parliament.

A post-Captain from 1720, Townsend commanded various ships. As captain of HMS Shrewsbury he took part in the expedition against Cartagena in 1741. He was promoted to Rear Admiral in 1744, Vice Admiral in 1746 and Admiral in 1747. He was also an Elder Brother of Trinity House.

He entered Parliament in 1744 as member for the naval port of Portsmouth, and represented that town until 1754. He did not stand for re-election in 1754, when the Admiralty supported two other Admirals as its candidates. He became governor of Greenwich Hospital in 1754, and in this capacity in 1757 he had custody of Admiral Byng, who was under arrest there before his court-martial. After Byng's execution, Townsend was chosen to take his place as MP for Rochester, another borough in the Admiralty's gift, and was MP for that city for the rest of his life. He was regarded as a reliable voter for the government, but seems never to have spoken in the House.

He was elected a Fellow of the Royal Society in February 1750.

Townsend married Elizabeth Larcum, daughter of William Larcum, a surgeon, and they had one son and one daughter. He died in 1765.
