Who was US president during the Suez Crisis?

In 1952, Egypt's monarchy was removed in a military coup. The new government nationalized the Suez Canal, in which the British and French government owned a substantial stakes; Israeli shipping was also blocked from going through. The invasion went well, but the US backed Egyptian President Nasser; Eisenhower threatened to sell US holdings of the British pound, an act which would have led to the collapse of the British currency. The crisis made Nasser very popular among Arabs. France's DGSE afterwards made several unsuccessful attempts on Nasser's life.
