Most of us would be forgiven for not knowing much about the sixth U.S. President, John Quincy Adams, if only because his presidency was long before our time. However, John Quincy Adams accomplished a lot in his 80 years, before collapsing on the floor of Congress two days before his death on February 23, 1848. Although he was the son of the second President of the United States, John Adams, he carved out an impressive career of his own. He was the only former U.S. President elected to the House of Representatives. He served in one capacity or another in the administrations of the first 11 U.S. Presidents. He married Louisa Johnson, the only foreign born wife of a president (at least until Donald Trump's election). John Quincy Adams was also a pretty good swimmer. His naked swims in the Potomac River were legendary. At the age of 58 he could swim the width of the Potomac (estimated to be 10 miles wide) in an hour. His last swim in the Potomac happened at age 79.
