Samuel Lysons (bap. 1763 – d. 1819) was the second son of Samuel Lysons (1730-1804), rector of Rodmarton and Cherrington, Gloucestershire, and his wife Mary (1734-1791). His brother was the historical topographer Daniel Lysons (1762-1834). Lysons attended Bath grammar school and in June 1780 began to work for a Bath Solicitor named Jeffries. In October 1874, Lysons moved to London and began studying law under a Mr Walton. He practiced as a special pleader for several years and was not called to the bar until June 1798. In July 1796, he was introduced to George III by Sir Joseph Banks, becoming a favourite of the Royal family.
Lysons was ambitious and friends with many leading personalities including Horace Walpole, whilst Samuel Johnson met him and was impressed. In December 1803, he was appointed keeper of records in the Tower of London and ceased practicing law. He did a considerable amount towards arranging the archives and managed to increase the staff from one to six. He held the post until his death.
Lysons became a fellow of the Society of Antiquaries in November 1786 and in November 1812 he was nominated one of the vice-presidents of the society, from 1798 to 1809 he held the honorary office of director. He was elected fellow of the Royal Society in February 1787, becoming vice-president and treasurer of the society in 1810.
He was an artist of some skill, occasionally exhibiting at the Royal Academy between 1785 and 1796. Lysons was also a field archaeologist and reports on sites, which he worked including Woodchester Roman pavement, reveal he was ahead of his time. His reports were lavishly illustrated. In 1818 he was chosen to fill the position of antiquary professor at the Royal Academy. He died of heart failure on 29 June 1819 at Cirencester, Gloucestershire.
