Question: Which U.S. president served the shortest term in office?

Answer: William Henry Harrison served the shortest presidency in U.S. history, lasting just 31 days after taking office in 1841. He caught pneumonia shortly after delivering the longest inaugural address ever, reportedly without a coat or hat in cold weather, and died a month later. His death marked the first time a U.S. president died in office, setting an important precedent for presidential succession.
