dissection proof


... the German mathematician Max Dehn showed in $1901$ that there are two polyhedra of the same volume for which it is impossible to reconstruct one from the other by dissection.


In fact it was $1900$ in which he performed this feat.

This mistake is repeated in entry equidecomposable.

The date of this result is not reported in the second edition.
