Charles Thomson (November 29, 1729 – August 16, 1824) was an Irish-born patriot leader in Philadelphia during the American Revolution and the secretary of the Continental Congress (1774–1789) throughout its existence. As secretary, Thomson, a Founding Father of the United States, prepared the Journals of the Continental Congress, and his and John Hancock's names were the only two to appear on the first printing of the United States Declaration of Independence.

Thomson is also known for co-designing the Great Seal of the United States and adding its Latin mottoes Annuit cœptis and Novus ordo seclorum, and for his translation of the Bible's Old Testament.

After the death of his wife in 1739, John Thomson migrated to the British colonies in North America with his sons (three or four brothers, including Charles). John Thomson died at sea, his possessions stolen, and the penniless boys were separated on arrival at New Castle, Delaware. Charles was first cared for by a blacksmith in New Castle and was educated in New London, Pennsylvania. In 1750 he became a tutor in Latin at the Philadelphia Academy, an ancestor school of the University of Pennsylvania.

Political career

During the French and Indian War, Thomson was an opponent of the Pennsylvania proprietors' American Indian policies. He served as secretary at the 1758 Treaty of Easton and wrote An Enquiry into the Causes of the Alienation of the Delaware and Shawanese Indians from the British Interest (1759), which blamed the war on the proprietors. The Delaware Indians adopted him into their tribe calling him, 'The-man-who-speaks-the-truth'. He was allied with Benjamin Franklin, the leader of the anti-proprietary party, but the two men parted politically during the crisis over the Stamp Act 1765. Thomson became a leader of Philadelphia's Sons of Liberty. He was inducted into the American Philosophical Society around 1750.

Thomson was a leader in the revolution of the early 1770s. John Adams called him the "Samuel Adams of Philadelphia". Thomson served as the secretary of the Continental Congress in its entirety. Through those 15 years, the Congress saw many delegates come and go, but Thomson's dedication to recording the debates and decisions provided continuity. Along with John Hancock, the president of the Congress, Thomson's name (as secretary) appeared on the first published version of the Declaration of Independence in July 1776.

Thomson's role as secretary to Congress was not limited to clerical duties. According to biographer Boyd Schlenther, Thomson "took a direct role in the conduct of foreign affairs." Fred S. Rolater has suggested that Thomson was essentially the "Prime Minister of the United States."

Thomson is also noted for designing, with William Barton, the Great Seal of the United States, which played a prominent role in the ratification of the Treaty of Paris on January 14, 1784 (Ratification Day). Britain's representatives in Paris initially disputed the placement of the Great Seal and Congressional President Thomas Mifflin's signature until they were mollified by Benjamin Franklin. When designing the final version of the Great Seal, Thomson (a former Latin teacher) kept the pyramid and eye for the reverse side but replaced the two mottos, using Annuit Cœptis instead of Deo Favente (and Novus ordo seclorum instead of Perennis). When he provided his official explanation of the meaning of this motto, he wrote:

Thomson's service was not without its critics. James Searle, a delegate and close friend of John Adams, began a cane fight on the floor of Congress against Thomson over a claim that he was misquoted in the minutes that resulted in both men being slashed in the face. Such brawls on the floor were common, and many of them were prompted by argument over Thomson's recordings. Political disagreements prevented Thomson from getting a position in the new government created by the U.S. Constitution.
