Charles Thomson. He was the first and only Secretary of the Continental Congress. His name is on the first printing of the Declaration of Independence. The manuscript Journals of the Continental Congress are in his hand. He created the final, approved design for the Great Seal of the United States, still in use today. He was the “Sam. Adams of Phyladelphia.” And yet, his name carries a fraction of the recognition of Washington, Hancock, Jefferson, or Adams (neither John nor the original “Sam. Adams”). Thomson’s obscured legacy was partly his own doing, as he apparently destroyed the bulk of his papers concerning the American Revolution, and party because he spent the last third of his life removed from the political sphere. For this month’s Research Highlight, we selected ten interesting aspects of Thomson’s life and character.
