Thomas Jefferson was the first president to be sworn in in Washington, D.C.
While other dignitaries took their finest carriages to the Capitol for Thomas Jefferson's inauguration, Jefferson walked. He then walked back to his boarding house for dinner.
For his second term, Jefferson arrived on horseback. By then, the "President's House" was finished and his journey down Pennsylvania Avenue to what we now call the White House inspired an impromptu celebration of music and cheering crowds - the precursor of today's Inaugural Parade.
Jefferson also began another tradition: the Open House, inviting the public to the Executive Mansion for a party.
