WRONG! Truman served from 1945 to 1953, completing FDR’s term and then winning his own full term. Although he had significant influence on U.S. history, he did not serve non-consecutively, which could mislead someone thinking of influential presidents.

CORRECT! Grover Cleveland is the only U.S. president to serve two non-consecutive terms, first from 1885 to 1889 and then again from 1893 to 1897. He is both the 22nd and 24th president, making him unique in American history for holding this distinction.
