Robert Francis "Bobby" Kennedy (November 20, 1925 – June 6, 1968), also referred to by his initials RFK, was an American politician, a Democratic senator from New York, and a noted civil rights activist. An icon of modern American liberalism and member of the Kennedy family, he was a younger brother of President John F. Kennedy and acted as one of his advisors during his presidency. From 1961 to 1964, he was the U.S. Attorney General.

Following his brother John's assassination on November 22, 1963, Kennedy continued to serve as Attorney General under President Lyndon B. Johnson for nine months. In September 1964, Kennedy resigned to seek the U.S. Senate seat from New York, which he won in November. Within a few years, he publicly split with Johnson over the Vietnam War.

In March 1968, Kennedy began a campaign for the presidency and was a front-running candidate of the Democratic Party. In the California presidential primary on June 4, Kennedy defeated Eugene McCarthy, a U.S. Senator from Minnesota. Following a brief victory speech delivered just past midnight on June 5 at The Ambassador Hotel in Los Angeles, Kennedy was shot by Sirhan Sirhan. Mortally wounded, he survived for nearly 26 hours, dying early in the morning of June 6.

Jesse Woodson James (September 5, 1847 – April 3, 1882) was an American outlaw, gang leader, bank robber, train robber and murderer from the state of Missouri and the most famous member of the James-Younger Gang. Already a celebrity when he was alive, he became a legendary figure of the Wild West after his death. Some recent scholars place him in the context of regional insurgencies of ex-Confederates following the American Civil War rather than a manifestation of frontier lawlessness or alleged economic justice.

Jesse and his brother Frank James were Confederate guerrillas during the Civil War. They were accused of participating in atrocities committed against Union soldiers. After the war, as members of one gang or another, they robbed banks, stagecoaches and trains. Despite popular portrayals of James as a kind of Robin Hood, robbing from the rich and giving to the poor, there is no evidence that he and his gang used their robbery gains for anyone but themselves.

The James brothers were most active with their gang from about 1866 until 1876, when their attempted robbery of a bank in Northfield, Minnesota, resulted in the capture or deaths of several members. They continued in crime for several years, recruiting new members, but were under increasing pressure from law enforcement. On April 3, 1882, Jesse James was killed by Robert Ford, who was a member of the gang living in the James house and who was hoping to collect a state reward on James' head.

Walter "Walt" Whitman (May 31, 1819 – March 26, 1892) was an American poet, essayist and journalist. A humanist, he was a part of the transition between transcendentalism and realism, incorporating both views in his works. Whitman is among the most influential poets in the American canon, often called the father of free verse. His work was very controversial in its time, particularly his poetry collection Leaves of Grass, which was described as obscene for its overt sexuality.

Born on Long Island, Whitman worked as a journalist, a teacher, a government clerk, and – in addition to publishing his poetry – was a volunteer nurse during the American Civil War. Early in his career, he also produced a temperance novel, Franklin Evans (1842). Whitman's major work, Leaves of Grass, was first published in 1855 with his own money. The work was an attempt at reaching out to the common person with an American epic. He continued expanding and revising it until his death in 1892. After a stroke towards the end of his life, he moved to Camden, New Jersey, where his health further declined. He died at age 72 and his funeral became a public spectacle.
