Youngest U.S. President

September 14, 1901

42-year-old Theodore Roosevelt is sworn in, making him the youngest U.S. president. Roosevelt became president after the assassination of President McKinley. He did not use a Bible for his oath of office.
He was the first U.S. president to ride in an automobile (1902), submerge in a submarine (1905), and fly in an airplane (1910). He was also the only U.S. president not to use the word “I” in his inaugural address (1905), and the first American to win a Nobel Peace Prize (1906). Also known for his motto, “Speak softly and carry a big stick.” Even though he was shot while on his way to deliver a speech, he delivered the speech before going to the hospital. Known for his athleticism, during his presidency he participated in a boxing match that cost him his sight in his left eye (1904). Note: John F. Kennedy, at age 43, was the youngest elected president.
