The synopsis

Christine Ladd-Franklin (December 1, 1847 – March 5, 1930) was an American psychologist, logician, and mathematician. Born Christine Ladd in Windsor, Connecticut, she displayed early academic promise and pursued education at Wesleyan Academy and Vassar College, where she was mentored by Maria Mitchell. Despite facing significant gender-based barriers in higher education, she completed all requirements for a PhD in mathematics and logic at Johns Hopkins University in 1882, though the degree was only officially awarded to her in 1926. Ladd-Franklin made substantial contributions to the fields of logic and psychology, most notably developing a theory of color vision based on evolutionary principles. She was also an advocate for women's rights throughout her life.
