Charles Carroll (September 19, 1737 – November 14, 1832) was the only Catholic to sign the Declaration of Independence and the longest survivor, dying 56 years after its signing.
Carroll was known as the “First Citizen” of the American colonies, a consequence of signing articles in the Maryland Gazette with that pen name. He was one of the wealthiest and most formally educated of the signers of the Declaration of Independence. Carroll had a 17-year Jesuit education in France and spoke five languages fluently. Although he was born in the United States, as a Catholic, he was barred from holding office in Maryland due to the 1704 act seeking to “prevent the growth of Popery in this Province.”
