Which U.S. President was nicknamed Ike?

The nickname "Ike" refers to Dwight D. Eisenhower, who served as the 34th President of the United States from 1953 to 1961. The origin of this affectionate nickname stems from his last name, "Eisenhower," which is often abbreviated to "Ike" as a more approachable and familiar term. This informal name became widely recognized during his military career and later in his political life, contributing to his public persona. Eisenhower is remembered for his leadership during World War II as Supreme Commander of the Allied Expeditionary Force and for his two-term presidency that emphasized peace, prosperity, and the containment of communism during the Cold War era.

The other individuals listed—William Howard Taft, Warren G. Harding, and Calvin Coolidge—do not share this nickname or a similarly recognized moniker and are known for different contributions and contexts in U.S. history.
