IN: William Jefferson Clinton (ne Blythe III; born August 19, 1946) is an American politician who served as the 42nd President of the United States from 1993 to 2001. Prior to the presidency, he was the Governor of Arkansas from 1979 to 1981, and again from 1983 to 1992. A member of the Democratic Party, Clinton was ideologically a New Democrat and many of his policies reflected a centrist "Third Way" political philosophy. Clinton was born and raised in Arkansas and attended Georgetown University, the University of Oxford, and Yale Law School.

Clinton was born William Jefferson Blythe III on August 19, 1946, at Julia Chester Hospital in Hope, Arkansas. He was the son of William Jefferson Blythe Jr. (1918-1946), a traveling salesman who had died in an automobile accident three months before his birth, and Virginia Dell Cassidy (later Virginia Kelley: 1923-1994). His parents had married on September 4, 1943, but this union later proved to be bigamous, as Blythe was still married to his third wife. Soon after Bill was born, Virginia traveled to New Orleans to study nursing. She left her son in Hope with her parents Eldridge and Edith Cassidy, who owned and ran a small grocery store. At a time when the southern United States was racially segregated, Clinton's grandparents sold goods on credit to people of all races. In 1950, Bill's mother returned from nursing school and married Roger Clinton Sr., who owned an automobile dealership in Hot Springs, Arkansas, with his brother and Earl T. Ricks. The family moved to Hot Springs in 1950.  Although he immediately assumed use of his stepfather's surname, it was not until Clinton turned 15 that he formally adopted the surname Clinton as a gesture toward his stepfather. Clinton said that he remembered his stepfather as a gambler and an alcoholic who regularly abused his mother and half-brother, Roger Clinton Jr., to the point where he intervened multiple times with the threat of violence to protect them.  In Hot Springs, Clinton attended St. John's Catholic Elementary School, Ramble Elementary School, and Hot Springs High School, where he was an active student leader, avid reader, and musician. Clinton was in the chorus and played the tenor saxophone, winning first chair in the state band's saxophone section. He briefly considered dedicating his life to music, but as he noted in his autobiography My Life:  Clinton began an interest in law at Hot Springs High, when he took up the challenge to argue the defense of the ancient Roman Senator Catiline in a mock trial in his Latin class. After a vigorous defense that made use of his "budding rhetorical and political skills", he told the Latin teacher Elizabeth Buck that it "made him realize that someday he would study law".  Clinton has identified two influential moments in his life, both occurring in 1963, that contributed to his decision to become a public figure. One was his visit as a Boys Nation senator to the White House to meet President John F. Kennedy. The other was watching Martin Luther King Jr.'s 1963 I Have a Dream speech on TV, which impressed him enough that he later memorized it.

IN: David Monroe Shoup (30 December 1904 - 13 January 1983) was a decorated general of the United States Marine Corps who was awarded the Medal of Honor in World War II, became the 22nd Commandant of the Marine Corps, and, after retiring, became one of the most prominent critics of the Vietnam War. Born in Indiana to an impoverished family, Shoup joined the military for financial reasons. Rising through the ranks in the interwar era, he was twice deployed to China during the Chinese Civil War. He served in Iceland at the beginning of U.S. involvement in World War II, and as a staff officer during the Pacific War.

David Monroe Shoup was born on 30 December 1904 in Battle Ground, Indiana. His family lived on a farm in Ash Grove, but moved to Covington to live on a new farm in 1916. At age 12 he was enrolled in Covington High School, a competitive high school with an advanced curriculum. Shoup was an excellent student, maintaining high marks in French, English, physics, and history. Additionally, he was involved in several extracurricular activities, including basketball, and was class president in his senior year. He graduated in 1921. He later affectionately referred to his impoverished upbringing as that of an "Indiana plowboy." Regarded by friends as very sociable, he met Zola De Haven in his freshman year and later said he had been instantly attracted to her. They were both very competitive in academics and athletics, and the two dated throughout high school; they were married in 1931.  After high school, Shoup attended DePauw University where he was one of 100 awarded the Edward Rector Scholarship, giving him full tuition. Majoring in mathematics, he joined the Delta Upsilon fraternity and maintained high marks, narrowly failing the selection criteria for Phi Beta Kappa Society. He was on the track and field and rifle teams, and also competed in the wrestling and football teams. He won the Indiana and Kentucky Amateur Athletic Union marathon in 1925. He waited tables, washed dishes and worked in a cement factory to help pay his expenses. Lack of funds compelled him to take a year off after his junior year to teach school, and his expenses were further strained when he contracted a severe case of pneumonia and incurred hospital bills. He opted to enroll in the Reserve Officers Training Corps (ROTC) to offset his living expenses, and later recalled that this was the only reason he joined the military. He graduated from DePauw in 1926.  From an early age, Shoup was molded by the progressive ideas of Indiana politicians, sympathizing with rural progressives fighting against the interests of big businesses. He developed an anti-imperialist attitude, and his skepticism about American foreign policy, influenced by his small-town background, made him an outspoken opponent of the unnecessary use of military force. He felt the use of troops for economic or imperialist consideration was wrong, a viewpoint he would carry for his entire career.
