Which U.S. president gave only one official speech while in office? Correct
William Henry Harrison is the U.S. president who gave only one official speech while in office. While Andrew Jackson, Ulysses S. Grant, and Andrew Johnson all had unique presidential terms with various speeches and addresses made during their time in office, it was Harrison who delivered just one official speech, his inaugural address, before falling ill with pneumonia and passing away shortly thereafter. Harrison’s brief presidency, lasting only 31 days, is one of the shortest in U.S. history, and his limited time in office meant he had little opportunity to deliver additional speeches or enact significant policies.
