Historical Note

The Second Pizza Theorem has been around for many years, and it is not possible to identify its origin.

It appeared in print as long ago as $2002$, on page $2251$ of the CRC Concise Encyclopedia of Mathematics.

It has probably had multiple originators who discover it independently.
