Final answer:
Dr. George R. Carruthers worked at the Naval Research Laboratory in Washington, D.C., and is known for his contributions to ultraviolet astronomy, not to be confused with George Washington Carver or Booker T. Washington.
Step-by-step explanation:
Dr. George R. Carruthers is an acclaimed physicist and inventor known for his work in the field of ultraviolet astronomy. However, the question seems to mix references to George Washington Carver, Booker T. Washington, and a verbal confusion with George Washington. Dr. Carruthers worked at the Naval Research Laboratory in Washington, D.C., where he developed space-based observatory tools, including the far-UV camera/spectrograph used in the Apollo 16 mission to the moon. It seems there might be some confusion, as the information provided does not pertain to Dr. Carruthers but instead relates to different historical figures named Washington who contributed to African American education, politics, and the social climate of their times.
