Ms. Klau's initiative to commemorate the children killed in the Holocaust with the creation and collection of a million and a half butterflies was inspired by the poem "The Butterfly," written by Pavel Friedmann. The poem considers the butterfly a symbol of freedom which so contrasts with life in the ghetto.
The last, the very last,
So richly, brightly, dazzlingly yellow.
Perhaps if the sun's tears would sing
against a white stone. . . .
Such, such a yellow
Is carried lightly 'way up high.
It went away I'm sure because it wished to
kiss the world good-bye.
For seven weeks I've lived here,
penned up inside this ghetto.
But I have found what I love here.
The dandelions call to me
and the white chestnut branches in the court.
Only I never saw another butterfly.
That butterfly was the last one.
Butterflies don't live here,
in the ghetto.
