Who commanded the Allied D-Day invasion of Normandy in 1944 and later became US president?

Dwight D. Eisenhower commanded the Allied D-Day invasion of Normandy in 1944 and later became the 34th president of the United States.

As Supreme Commander of the Allied Expeditionary Force, Eisenhower coordinated the enormous cross-Channel assault launched on June 6, 1944. The operation required cooperation among American, British, Canadian, and other Allied forces, along with thousands of ships and aircraft. His most famous pre-invasion message acknowledged the operation's risks and the soldiers' courage.

Eisenhower was not the field commander of every unit landing on the beaches. Generals such as Omar Bradley led major American ground forces, while Bernard Montgomery directed the invasion's land component. Eisenhower's role was overall command and strategic coordination, which is why he is the canonical answer.

After World War II, Eisenhower served as Army chief of staff, president of Columbia University, and NATO's first Supreme Allied Commander Europe. He won the 1952 and 1956 presidential elections and served two terms from 1953 to 1961.
