WILLIAM HOWARD TAFT, 27TH PRESIDENT - Sworn in as President on March 4, 1904, William Howard Taft was the first President to ride to his inauguration parade with his wife. His was the first inauguration parade to also include an automobile, and that evening the U.S. Capitol dome was lighted for the first time (with a searchlight). Taft was the heaviest of all U.S. Presidents, requiring a special bathtub to be installed in the White House to accommodate him. After serving as President, Taft became the only U.S. President to later go on and serve as Chief Justice of the U.S. Supreme Court.

WILLIAM McKINLEY, 25TH PRESIDENT - William McKinley was sworn in as President on March 4, 1897. His was the first inauguration to be filmed by a movie camera. Ironically, his was also the first inauguration where a glass-enclosed reviewing stand was constructed in front of the White House to provide greater security for the newly-elected President. This enhanced presidential security did not protect him as later in his presidency he became the third U.S. President to be assassinated.

WILLIAM HENRY HARRISON, 9TH PRESIDENT - William Henry Harrison was sworn in as the 9th U.S. President on March 4, 1841. His campaign slogan - "Tippecanoe and Tyler Too" - referred to his defeat of the Native Americans under the leadership of Tecumseh and his brother The Prophet at the Battle of Tippecanoe, and was the first presidential campaign to use a campaign slogan. He was the first President-elect to arrive in Washington, D.C. for his inauguration by train, while his was the longest of all inaugural speeches (10,000 words). His inaugural address was unusual in that he began it before taking the oath of office, then took the oath of office, and then resumed his speech. His presidency was the shortest of all U.S. Presidents, dying not long after his inauguration from pneumonia that he caught from giving such a long inauguration speech in the bitter cold.
