Lincoln suspended it during the War Between the States. Many of Lincoln's actions during the war, including the imposition of an income tax were later ruled Unconstitutional.
It could be argued that California Attourney General Earl Warren and later President Roosevelt suspended it with the internment of American Citizens of Japanese ancestry during the Second World War.
