He had been the ‘White House’ chief of staff under presidents Richard Nixon and Gerald Ford and the United States secretary of state under President Ronald Reagan. Born and raised in Pennsylvania, Alexander graduated high school in 1942 and joined the ‘United States Military Academy.’ He served in the Korean War and the Vietnam War for the United States. Between the two wars, he served as an associate to the United States secretary of defense Robert McNamara. His contribution to the American military earned him the ‘Distinguished Service Cross’ honor, along with the ‘Silver Star’ and the ‘Purple Heart.’ In 1969, he began working as an assistant to Henry Kissinger, the erstwhile national security advisor. In 1973, he entered the ‘White House’ as the chief of staff of President Richard Nixon and gained a massive influence. Soon, he came to be known to be one of the key persons who persuaded Nixon to resign. Alexander was made the secretary of state in 1980, after Ronald Reagan won the presidential elections. In 1982, he officially resigned from the cabinet. He sought a presidential nomination from the ‘Republican Party’ in the 1988 elections but was unsuccessful in his attempts.
