Science does not belong to just one civilization, one culture, one country, or one gender; it belongs to all who want to unfold the mysteries of nature. Most scientists agree that science currently is, and indeed always has been, international and multicultural in character. Our teaching at all levels should reflect this multiculturalism as part of the true nature of science. At present, however, it does not. This is not primarily due to a lack of historical information; it is due to the way popular introductory physics textbooks are written. It is time to correct the situation.
