What U.S. President's motto was "the buck stops here"?

What U.S. President's motto was “the buck stops here”? Harry S. Truman is the president associated with the phrase.

“The Buck Stops Here” was displayed on a sign Truman kept on his desk in the Oval Office. The expression means that the person in charge accepts ultimate responsibility for decisions and outcomes rather than passing blame to subordinates. It became strongly linked with Truman’s presidency and leadership style.

The wording uses “buck” in the sense of responsibility, not money. The phrase is related to the older expression “passing the buck,” meaning to shift responsibility to someone else. Truman’s sign presented the opposite principle: presidential decisions ultimately stopped with him.

A common misconception is that Truman invented the expression. The phrase existed before his presidency, but the desk sign made it famous as a symbol of executive accountability. Truman served as the 33rd U.S. president from 1945 to 1953, taking office after Franklin D. Roosevelt’s death and leading the country through the final months of World War II and the early Cold War.
