Lemuel "Francis" Abbott was an English portrait painter, famous for his painting of Horatio Nelson, 1st Viscount Nelson and for those of other naval officers and literary figures of the 18th century.

Admiral Sir Robert Calder, 1st Baronet, was a British naval officer who served in the Seven Years' War, the American Revolutionary War, the French Revolutionary Wars and the Napoleonic Wars. For much of his career he was regarded as a dependable officer, and spent several years as Captain of the Fleet under Admiral Sir John Jervis. However, he is chiefly remembered for his controversial actions following the Battle of Cape Finisterre in 1805 which resulted in his court-martial. Though he was removed from his sea command, he was retained in the Navy and later served as Commander-in-Chief of the base at Plymouth.
