The president who died earliest in office was William Henry Harrison.
William Henry Harrison, the ninth President of the United States, holds the distinction of serving the shortest tenure in U.S. presidential history. Elected in 1841, Harrison was notably the oldest president to be elected at the time. He tragically passed away on his 32nd day in office, making him the first U.S. president to die while serving.
A Brief but Historic Presidency
Harrison's presidency was remarkably brief, lasting just 31 full days. His death profoundly impacted American political history, setting a crucial precedent for presidential succession. Prior to his demise, Harrison was an accomplished American military officer and politician, famed for his military career. His untimely death occurred on April 4, 1841, just one month after his inauguration on March 4, 1841.

Historical Significance
Harrison's death established a critical precedent for vice-presidential succession. Following his passing, Vice President John Tyler assumed the presidency, asserting his right to the full powers and title of President, rather than merely acting as President. This practice, known as "Tyler's Precedent," was later formally codified by the 25th Amendment to the U.S. Constitution in 1967, ensuring a clear line of succession in the event of a president's death, resignation, or removal from office.
