Stein Limerick

There once was a family named Stein;

There’s Gertrude, and Heller, and Ein.

Gertrude’s poems are jeered

Heller’s logic is weird

and nobody understands Ein.

Comment by Hellerstein:

Of the three of us;

Two of us are poets,

Two of us are mathematicians,

Two of us are famous,

Yet none of us is a famous mathematical poet!
