About Charles Sanders Peirce
Charles Sanders Peirce ( /ˈpɜrs/ like "purse"; September 10, 1839 – April 19, 1914) was an American philosopher, logician, mathematician, and scientist, born at 3 Phillips Place in Cambridge, Massachusetts. Peirce was educated as a chemist and employed as a scientist for 30 years. Today he is appreciated largely for his contributions to logic, mathematics, philosophy, and semiotics, and for his founding of pragmatism. In 1934, the philosopher Paul Weiss called Peirce "the most original and versatile of American philosophers and America's greatest logician".
An innovator in mathematics, statistics, philosophy, research methodology, and various sciences, Peirce considered himself a logician first and foremost. He made major contributions to logic, but logic for him encompassed much of that which is now called epistemology and philosophy of science. He saw logic as the formal branch of semiotics, of which he is a founder. As early as 1886 he saw that logical operations could be carried out by electrical switching circuits, the same idea as was used decades later to produce digital computers.
