Attempted assassination of Theodore Roosevelt -

Theodore Roosevelt had a miraculous escape after an assassin's otherwise lethal bullet was impeded by a 50-page campaign speech folded over twice in Roosevelt's breast pocket and a metal glasses case that deflected the slug. Roosevelt, who had served as the 26th president of the United States, was campaigning in Milwaukee on October 14, 1912, as the Bull Moose candidate for the US presidency. He's pictured greeting supporters before the failed assassination attempt.

John Flammang Schrank (1876–1943) -

The man who fired the gun was John Flammang Schrank, a Bavarian-born saloonkeeper from New York. Schrank had stalked Roosevelt through eight states in an effort to catch the right moment to kill him. The would-be assassin was diagnosed with paranoid schizophrenia and committed to an institution for the criminally insane, where he lived until his death in 1943.

Fortunately, two security personnel spotted Bergerson and quickly disarmed him. The failed assassin was later declared insane and spent the rest of his days in an asylum.

Arthur Bremer -

Bremer had planned to attack Nixon as the president's motorcade drove past him, but Nixon's car was traveling too fast for him to get a good shot. A few weeks later, he instead shot and seriously injured the governor of Alabama, George Wallace (pictured), leaving him paralyzed for the rest of his life. Bremer served 35 years in prison for the shooting of Governor Wallace.

Raymond Lee Harvey -

Harvey had a history of mental illness, but police were compelled to investigate further after he claimed to be part of a four-man operation to assassinate the president at the mall (pictured). Harvey and another man, an illegal Mexican alien who gave the name Osvaldo Espinoza Ortiz, were arrested but later released due to lack of evidence. The names "Lee Harvey" and "Osvaldo" (Osvaldo is the Spanish equivalent to "Oswald") led conspiracy theorists to draw comparisons to Lee Harvey Oswald.

Attempted assassination of Ronald Reagan -

The March 30, 1981, shooting of Ronald Reagan is the nearest anyone has gotten to claiming the life of a sitting US president since the assassination of President John F. Kennedy in 1963. Reagan was leaving the Washington Hilton hotel when his attacker struck.

John Hinckley Jr. -

The would-be assassin was later identified as John Hinckley Jr. Hinckley fired six shots towards the president, striking him and three others.

Assassination of Abraham Lincoln -

While Ronald Reagan was very fortunate to have survived the assassination attempt on him, four other US presidents weren't so lucky.

He died the following day.

John Wilkes Booth (1838–1865) -

Assassination of James A. Garfield -

James A. Garfield, the 20th president of the United States, survived being shot for 11 weeks before succumbing to his wounds. The assassin struck on July 2, 1881, at the Baltimore and Potomac Railroad Station in Washington, D.C., less than four months after Garfield had taken office.

Charles J. Guiteau (1841–1882) -

Garfield's killer was Charles J. Guiteau, an delusional American who felt aggrieved for not having been recognized by the administration with a consulship, based either in Paris or Vienna. His frustration boiled over into murderous intent. Guiteau was sentenced to death for the crime and was hanged five months later.

Assassination of William McKinley -

The assassination of William McKinley took place on September 6, 1901, at the Temple of Music in Buffalo, New York.

Mortally wounded, McKinley died eight days later.

Leon Czolgosz (1873–1901) -

McKinley's assassin was American laborer and anarchist Leon Czolgosz. At his trial, the gunman pleaded insanity, but was nonetheless found guilty of murder. Czolgosz's last words before his execution were_ "I shot the president because I thought it would help the working people and for the sake of the common people. I am not sorry for my crime."

Assassination of John F. Kennedy -

The most infamous assassination of an American president took place on November 22, 1963, in Dallas, Texas. President John F. Kennedy was shot once in the back, the bullet exiting via his throat, and once in the head. He died shortly after arriving at the city's Parkland Memorial Hospital.

Lee Harvey Oswald (1939–1963) -

One day after Kennedy's death, Lee Harvey Oswald, the man accused of carrying out the assassination, was himself shot and killed, gunned own by Jack Ruby. Harvey remains the man most likely to have murdered Kennedy, though conspiracy theorists to this day claim he was just one man in a much wider plot to kill the president.
