Thomas Erskine, 1st Baron Erskine, (10 January 1750 – 17 November 1823) was a British lawyer and politician who served as Lord Chancellor of the United Kingdom between 1806 and 1807 in the Ministry of All the Talents. In his retirement, as well as fighting for animal rights, Greek independence, and the defence of Queen Caroline, he wrote Armata, a strange tale of a man sailing to the moon upon a highway of ocean.
