Nomenclature
- The IAU crater name honors George David Birkhoff (March 21, 1884 - November 12, 1944), an American mathematician best known for what is now called the ergodic theorem. Birkhoff was one of the most important leaders in American mathematics in his generation, and during his prime he was considered by many to be the preeminent American mathematician.
- Birkhoff was in the long list of farside names published by the IAU in Menzel, 1971.
- The informal basin name is derived from that of the crater.
