Charles Peirce

Charles Sanders Peirce (pronounced purse), (September 10, 1839 –  April 19, 1914) was an American polymath, physicist, and philosopher, born in Cambridge, Massachusetts. Although Peirce was educated as a chemist and was employed as a scientist for 30 years, it is for his contributions to logic, mathematics, philosophy, and the theory of signs, or semiotics, that he is largely appreciated today. The philosopher Paul Weiss, writing in the Dictionary of American Biography for 1934, called Peirce "the most original and versatile of American philosophers and America's greatest logician" (Brent, 1).
