John F. Kennedy
Arguably the most charismatic President of the United States, John F. Kennedy came from a powerful family, and was blessed with good looks in addition to his personal charisma.
Due to the charisma and style of John and Jackie, the Kennedy White House became known as Camelot. Alan Jay Lerner, Kennedy's Harvard classmate, even wrote a hit song "Camelot" for the Broadway musical, which was a personal favorite of President Kennedy.
Charles Manson
It was mentioned earlier that charismatic leaders could also use their influence for less-than-honorable purposes; the classic example of this abuse is Charles Manson.
Some people believe it was a combination of the drug LSD coupled with Manson's charismatic personality that allowed him to manipulate others. In the end, Susan Atkins along with other members of the Manson family, were found guilty of the murder of the 26-year-old movie actress Sharon Tate and four others.
