Truman was born in Lamar, Missouri in 1884. He was America's 33rd president, sworn in after President Roosevelt's sudden death in April, 1945.
In honor of his birthday, Missouri observes a state holiday every May 8. That means all state administrative offices are closed today, as are many county courthouses.
If you have business at a county office, call ahead to see if they are open.
