Concealing one's true medical condition from the voting public is a time-honored tradition of the American presidency. William Henry Harrison, who died of pneumonia in April of 1841, after only one month in office, was the first Chief Executive to hide his physical frailties. Nine years later Zachary Taylor's handlers refused to acknowledge that cholera had put the President's life in jeopardy; they denied rumors of illness until he was near death, in July of 1850, sixteen months into his presidency. During Grover Cleveland's second term, in the 1890s, the White House deceived the public by dismissing allegations that surgeons had removed a cancerous growth from the President's mouth; a vulcanized-rubber prosthesis disguised the absence of much of Cleveland's upper left jaw and part of his palate. The public knew nothing about the implant until one of the President's physicians revealed it in 1917, nine years after Cleveland's death.
