Since the office was established in 1789, 45 individuals have served as president of the United States. Of these, eight have died in office, of whom four were assassinated and four died of natural causes. In each of these instances, the vice president has succeeded to the presidency. This practice is now governed by Section One of the Twenty-fifth Amendment to the United States Constitution, ratified in 1967, which declares that, "the Vice President shall become President" if the president is removed from office, dies, or resigns. The initial authorization for this practice was provided by Article II, Section 1, Clause 6, of the U.S. Constitution.

The first incumbent U.S. president to die was William Henry Harrison, on April 4, 1841, only one month after Inauguration Day. He died from complications of what at the time was believed to be pneumonia. The second U.S. president to die in office, Zachary Taylor, died on July 9, 1850, from acute gastroenteritis. Abraham Lincoln was the third U.S. president to die in office, and was the first to be assassinated. He was shot by John Wilkes Booth on the night of April 14, 1865, and died the following morning. Sixteen years later, on July 2, 1881, James A. Garfield was shot by Charles J. Guiteau, surviving for 79 days before dying on September 19, 1881.

On September 14, 1901, William McKinley died, eight days after being shot by Leon Czolgosz. Next, Warren G. Harding suffered a heart attack, and died on August 2, 1923. On April 12, 1945, Franklin D. Roosevelt (who had just begun his fourth term in office) collapsed and died as a result of a cerebral hemorrhage. The most recent U.S. president to die in office was John F. Kennedy, who was shot by Lee Harvey Oswald on November 22, 1963, in Dallas, Texas.

April 4, 1841: William Henry Harrison

On March 26, 1841, William Henry Harrison became ill with a cold after being caught in a torrential downpour without cover. His symptoms grew progressively worse over the ensuing two days, at which time a team of doctors was called in to treat him. After making a diagnosis of right lower lobe pneumonia, they proceeded to place heated suction cups on his bare torso and to administer a series of bloodlettings, to supposedly draw out the disease. When those procedures failed to bring about improvement, the doctors treated him with ipecac, castor oil, calomel, and finally with a boiled mixture of crude petroleum and Virginia snakeroot. All this only weakened Harrison further.

Initially, no official announcement was made concerning Harrison's illness, which, the longer he remained out of public view, fueled public speculation and concern. By the end of the month large crowds were gathering outside the White House, holding vigil while awaiting any news about the president's condition. On the evening of April 4, 1841, nine days after becoming ill,Cleaves 160 and exactly one month after his inauguration, Harrison died at age 68. His last words were to his attending doctor, though assumed to be directed at Vice President John Tyler:

A 30-day period of mourning commenced following the president's death. Various public ceremonies, modeled after European royal funeral practices, were held. An invitation-only funeral service was also held, on April 7, in the East Room of the White House, after which Harrison's coffin was brought to Congressional Cemetery in Washington, D.C., where it was placed in a temporary receiving vault.

That June, Harrison's body was transported by train and river barge to North Bend, Ohio. Then, on July 7, 1841, the nation's 9th president was buried in a family tomb at the summit of Mt. Nebo, overlooking the Ohio Riverthe William Henry Harrison Tomb State Memorial.

Harrison's death sparked a brief constitutional crisis regarding succession to the presidency, as the U.S. Constitution was unclear as to whether Vice President Tyler should assume the office of president or merely execute the duties of the vacant office as acting president. Tyler claimed a constitutional mandate to carry out the full powers and duties of the presidency and took the presidential oath of office, setting the Tyler Precedent for an orderly transfer of presidential power when a president leaves office intra-term.

Coincidentally, all but one of the presidents who later died in office had, like Harrison, won a presidential election in a year ending in a zero (1840 through 1960). This pattern of tragedies came to be known as the Curse of Tippecanoe, or the Curse of Tecumseh, the name of the Shawnee leader against whom Harrison fought in the 1811 Battle of Tippecanoe. Also sometimes referred to as the Zero Factor legend, the pattern was disrupted by Ronald Reagan, who survived an assassination attempt in 1981 (69 days after taking office) and lived to complete two full terms.

July 9, 1850: Zachary Taylor

Zachary Taylor was known to have consumed copious amounts of ice water, cold milk, green apples, and cherries on July 4, 1850, after attending holiday celebrations and the laying of the cornerstone of the Washington Monument. That same evening, he became severely ill with an unknown digestive ailment. Doctors used popular treatments of the time. On the morning of July 9, the president asked his wife Margaret not to grieve saying:

Taylor died late that evening, five days after becoming ill, at age 65.Bauer, pp. 314–316. Contemporary reports listed the cause of death as "bilious diarrhea or a bilious cholera." He was succeeded by Vice President Millard Fillmore.

Taylor's funeral took place on July 13, and like Harrison's nine years earlier, was held in the East Room of the White House. Afterward, an estimated 100,000 people gathered along the funeral route to Congressional Cemetery where his coffin was placed temporarily in the Public Vault; that October it was transported to Louisville, Kentucky. On November 1, 1850, Taylor was buried in his family's burial ground on the Taylor estate, Springfield, which became the Zachary Taylor National Cemetery.

Almost immediately after his death, rumors began to circulate that he had been poisoned by pro-slavery Southerners, and various conspiracy theories persisted into the late-20th century. The cause of Taylor's death was definitively established in 1991, when his remains were exhumed and an autopsy conducted by Kentucky's chief medical examiner. Subsequent neutron activation analysis conducted at Oak Ridge National Laboratory revealed no evidence of poisoning, as arsenic levels were too low. The analysis concluded Taylor had contracted cholera morbus (acute gastroenteritis), as Washington had open sewers, and his food or drink may have been contaminated.

April 15, 1865: Abraham Lincoln

The assassination of Abraham Lincoln took place on Good Friday, April 14, 1865, as the Civil War was drawing to a close. He died the following morning at the age of 56. The assassination occurred five days after General Robert E. Lee and the Army of Northern Virginia surrendered to General Ulysses S. Grant and the Army of the Potomac following the Battle of Appomattox Court House. Lincoln was the first American president to be killed by an assassin. (The first U.S. president to be confronted by a would-be assassin was Andrew Jackson 30 years earlier, in January 1835.)

The assassination of President Lincoln was planned and carried out by the well-known stage actor John Wilkes Booth, a Confederate sympathizer, vehement in his denunciation of Lincoln, and a strong opponent of the abolition of slavery in the United States. Booth and a group of co-conspirators originally plotted to kidnap Lincoln, but later planned to kill him, Vice President Andrew Johnson, and Secretary of State William H. Seward in a bid to help the Confederacy's cause. Johnson's would-be-assassin, George Atzerodt did not carry out his part of the plan, and Johnson succeeded Lincoln as president while Lewis Powell only managed to wound Seward.

Lincoln was shot once in the back of his head while watching the play Our American Cousin with his wife Mary Todd Lincoln at Ford's Theatre in Washington, D.C., on the night of April 14, 1865. An army surgeon who happened to be at Ford's, Doctor Charles Leale, assessed Lincoln's wound as mortal. The unconscious president was then carried across the street from the theater to the Petersen House, where he remained in a coma for eight hours before dying the following morning.

Within two weeks of the manhunt for Lincoln's killers, on April 26, 1865, Booth and David Herold were caught in a tobacco barn in Port Conway, Virginia. While Herold surrendered, Booth was shot to death by Boston Corbett, a Union Corporal.

A three-week series of official functions were held following the president's death. He lay in state in the East Room of the White House which was open to the public on April 18. A funeral service was held the next day, and then the coffin was transported in a procession down Pennsylvania Avenue to the United States Capitol, where a ceremonial burial service was held in the rotunda. After lying in state at the Capitol, Lincoln's remains were transported by train to Springfield, Illinois, for burial. He was interred on May 4, 1865, at Oak Ridge Cemetery in Springfieldthe Lincoln Tomb State Historic Site since 1895.

September 19, 1881: James A. Garfield

The assassination of James A. Garfield happened in Washington, D.C., on July 2, 1881. Garfield was shot by Charles J. Guiteau at 9:30a.m., less than four months into his term as the nation's 20th president. He died 11 weeks later on September 19, 1881, at the age of 49. Vice President Chester A. Arthur succeeded him as president. Garfield was scheduled to leave Washington on July 2, 1881, for his summer vacation.Peskin, p. 581. On that day, Guiteau lay in wait for the president at the Baltimore and Potomac Railroad station, on the southwest corner of present-day Sixth Street and Constitution Avenue NW, Washington, D.C.

President Garfield came to the Sixth Street Station on his way to his alma mater, Williams College, where he was scheduled to deliver a speech. Garfield was accompanied by two of his sons, James and Harry, and Secretary of State James G. Blaine. Secretary of War Robert Todd Lincoln waited at the station to see the president off.Vowell, p. 160. Garfield had no bodyguard or security detail; with the exception of Abraham Lincoln during the Civil War, early U.S. presidents never used any guards.Peskin, p. 593.

As President Garfield entered the waiting room of the station, Guiteau stepped forward and pulled the trigger from behind at point-blank range. "My God, what is that?!" Garfield cried out, flinging up his arms. Guiteau fired again and Garfield collapsed.Peskin, p. 596. One bullet grazed Garfield's shoulder; the other hit him in the back, passing the first lumbar vertebra but missing the spinal cord before coming to rest behind his pancreas.Millard, pp. 189, 312.

Garfield, conscious but in shock, was carried to an upstairs floor of the train station.Peskin, pp. 596–597. Lincoln sent for D.C. Bliss, a prominent Washington physician, who soon arrived and examined Garfield's wounds several times, probing for the bullet that remained lodged in the president's body with his fingers and metal probes. Two additional doctors were summoned, and they also probed the entry wound. Eventually there were about twenty people in the room, including at least ten physicians. As Garfield was being cared for, Lincoln, thinking back to the death of his father, said "How many hours of sorrow I have passed in this town."Peskin, p. 597.
