The Science History Institute recognizes there are materials in our collections that may be offensive or harmful, containing racist, sexist, Eurocentric, ableist, or homophobic language or depictions. The history of science is not exempt from beliefs or practices harmful to traditionally marginalized groups. The Institute is engaged in ongoing efforts to responsibly present and address the evidence of oppression and injustice inextricable from the history of science.
