William Howard Taft III was born on August 7, 1915, and was the eldest of four sons born to Robert A. Taft (1889–1953) and Martha Wheaton Bowers (1889–1958),[3] daughter of Lloyd Wheaton Bowers (1859–1910), the former solicitor general of the United States from 1909 to 1910.[4]: 127 His three brothers were: Robert Taft Jr. (1917–1993), who was elected to the U.S. Senate; Lloyd Bowers Taft (1923–1985),[5] who worked as an investment banker in Cincinnati,[6] and Horace Dwight Taft (1925–1983), who became a professor of physics and dean at Yale.[7]
At the time of his birth, his grandfather had just ended his Presidency and had recently become the Kent Professor of Law and Legal History at Yale Law School.[8] Taft graduated from Yale University and earned a doctorate from Princeton University.[9]
After graduating from Princeton, Taft taught English at the University of Maryland and Haverford College. During World War II, Taft became an analyst in military intelligence. After the war ended, he went back to Yale and taught there.[9]
In 1953, President Eisenhower appointed Taft U.S. ambassador to Ireland. His task as ambassador was made easier by the fact that John A. Costello (Taoiseach, 1954–57) was a personal friend; Taft described Costello as "pleasant and unassuming" whereas he had found Éamon de Valera "formal and aloof". (His predecessor, George A. Garrett, had also found Costello more sympathetic than de Valera.) Taft played a considerable part in organizing Costello's successful state visit to the United States in March 1956.
