Walter S. McAfee is the African American mathematician and physicist who first calculated the speed of the moon.  McAfee participated in Project Diana in the 1940s - a U.S. Army program, created to determine whether a high frequency radio signal could penetrate the earth’s outer atmosphere. To test this, scientists wanted to bounce a radar signal off the moon and back to earth. But the moon was a swiftly moving target, impossible to hit without knowing its exact speed.
