Explanation:

William Henry Harrison was a Whig politician who was the 9th President of the United States from March 4 to April 4, 1841. Harrison died on the 32nd day of his presidency at the age of 68.

He was presidential candidate for the Whig party in 1836, but lost to Martin Van Buren. He won the elections in 1840, mainly because the economy was going badly. His vice president was John Tyler.

It was a very cold day on March 4, 1841 when Harrison made his first speech as president. He gave the longest inaugural speech in American history, almost two hours. He got a cold on March 26, according to the views of the time because of the bad weather during his speech. The common cold became pneumonia and despite various treatments he died a month after his speech - the first president to die during his tenure.
