Christine Ladd-Franklin

Christine Ladd-Franklin (1847-1930) was an American psychologist, logician, and mathematician. A student of Charles Sanders Peirce and James Joseph Sylvester, Ladd-Franklin was marginalized as a woman by academic institutions: she was denied a Ph.D. at Johns Hopkins University despite fulfilling all the requirements for the degree; she was also unable to secure regular academic employment during her entire career. Nonetheless, Ladd-Franklin's made groundbreaking contributions to the Algebra of Logic tradition; in particular her "antilogism", was a central subject of examination in the first half of the 20th century.
