There are profound expressions of remembrance of science and scientists, innovators and educators in Washington, DC. In this article, we survey the outdoor memorials and also include a few indoor memorials, if they are accessible to the public. There appears to be some predominance of physics and physicists, especially related to electricity among the memorials, but other areas of science are also represented. British and European scientists predominate, reflecting the time gap between memorials and contemporary science. Our coverage extends to a few concepts, such as education, with an emphasis on African American participation, energy, and the protection and conservation of the environment.
