The cause of Zachary Taylor's death is not well understood, nor is it well documented. On
July 4,
1850, Taylor was diagnosed by his physicians with
cholera morbus, a term that included
diarrhea and
dysentery but not true
cholera. Cholera,
typhoid fever, and
food poisoning have all been indicated as the source of the president's ultimately fatal gastroenteritis. More specifically, a hasty snack of iced milk, cold cherries and pickled cucumbers consumed at an
Independence Day celebration might have been the culprit. By
July 9, Taylor was dead.
In
1991, with permission from his descendants, Taylor's body was exhumed, and
Larry Robinson and Frank Dyer conducted an autopsy at the
Oak Ridge National Laboratory. At the exhumation, observers noted that Taylor's body, while somewhat decomposed, was still instantly recognizable as the 12th President — Taylor's brow ridge remained intact. Investigating the possibility of assassination by means of deliberate poisoning, Dyer and Robinson detected traces of
arsenic and sent the results to a Kentucky medical examiner, who determined the quantity of arsenic present — there is a faint amount of arsenic present naturally in the human body — was several hundred times less than there would have been had he been poisoned with arsenic. Despite these findings, assassination theories have not been entirely put to rest.
Michael Parenti devoted a chapter in his controversial 1999 book
History as Mystery to what he called "The Strange Death of Zachary Taylor". In it he speculates that Taylor was assassinated and that his autopsy was botched.
There is some strong evidence that Taylor died from complications of
heat stroke. On July 4, 1850, the weather in Washington was hot and rather humid. Taylor was there to preside over ceremonies at the laying of the cornerstone of the Washington Monument. Taylor was sporting a thick coat, vest, high-collared shirt, and a top hat. Shortly after arriving, Taylor complained that he was very thirsty. He went to the reception table and downed a large amount of water directly from a pitcher.
Since the water was sitting in the sun, the idea of cholera is a possibility. But Taylor exhibited classic symptoms of heat stroke, particularly red, flushed skin on the face. Records also indicate that Taylor was having trouble walking and exhibiting slurred speech. At no time while outside did anyone loosen or remove Taylor's clothing. Only after returning to the White House was some of his clothing loosened. It was only a short time before Taylor collapsed.
At this point his clothing was removed, but internal organs had already been damaged. In fact, his doctors were mystified as to the cause of multiple organ failure. Medical sciences had not addressed heat stroke and the internal damage caused by it. According to author Charles Panati, Taylor actually awoke briefly and said: "I should not be surprised if this were to result in my death." He took a few sips of iced milk, again adding to the possibility of cholera. He lapsed again into unconsciousness and died on
July 9,
1850.
Taylor is buried in
Louisville, Kentucky, at what is now the
Zachary Taylor National Cemetery.
