Based on the Ronald E. Mickens collection, this episode describes the history of the community of Black physicists in the United States. In 1999 the American Physical Society celebrated its centennial. In conjunction with the celebration, Dr. Ronald Mickens and his colleagues created an exhibit on the community of African American physicists and their contributions to the field during the twentieth century. In addition to providing a history of the African American presence in physics, this episode will also highlight several items in the Mickens collection.
