No President legalized Prohibition.
Constitutional amendments do not have anything to do with a President. The 18th amendment, having been approved by vote of the House of Representatives and the Senate, was submitted to the States for ratification.
When 3/4ths of the states ratified it, it took effect when the Secretary of State, Frank Polk, certified the ratification. This was on January 29th, 1919. Of course, the amendment itself had a provision that called for it not to take effect until one year after the ratification.
Woodrow Wilson was President in 1919. But his approval or disapproval was not relevant, and there was nothing for him to sign.
It began under Woodrow Wilson, was tolerated under Harding, Coolidge and Hoover. Prohibition was ended under FDR.
