Charles Santiago Sanders Peirce
About
Charles Santiago Sanders Peirce was the adopted name of Charles Sanders Peirce, an American philosopher, logician, mathematician, and scientist. Peirce's name appeared in print as "Charles Santiago Peirce" as early as 1890. Starting in 1906 he used "Santiago" in many of his own articles. There is no well-documented explanation of why Peirce adopted the middle name "Santiago" but speculations and beliefs of contemporaries and scholars focused on his gratitude to his old friend William James and more recently on Peirce's second wife Juliette.
