Benjamin Franklin was an American polymath and one of the Founding Fathers of the United States. Franklin was a leading writer, printer, political philosopher, politician, Freemason, postmaster, scientist, inventor, humorist, civic activist, statesman, and diplomat. As a scientist, he was a major figure in the American Enlightenment and the history of physics for his discoveries and theories regarding electricity. As an inventor, he is known for the lightning rod, bifocals, and the Franklin stove, among other inventions. He founded many civic organizations, including the Library Company, Philadelphia's first fire department, and the University of Pennsylvania.
Franklin suffered from obesity throughout his middle-aged and later years, which resulted in multiple health problems, particularly gout, which worsened as he aged. In poor health during the signing of the US Constitution in 1787, he was rarely seen in public from then until his death.
Benjamin Franklin died from pleuritic attack at his home in Philadelphia on April 17, 1790. He was aged 84 at the time of his death. His last words were reportedly, "a dying man can do nothing easy", to his daughter after she suggested that he change position in bed and lie on his side so he could breathe more easily.
