## 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.
