Wald was a member of the “Dror”
movement. During the Great
Uprising in the Warsaw
Ghetto, he commanded
a force in Toebbens-Shultz at 36 Leszno
Street. He was in charge of the prison established
by the Jewish
Fighting Organization and for the execution
of several traitors and collaborators.
He was nicknamed “Tatale” (daddy)
because of his short stature. Wald was
killed in May 1943 while making his way out of a sewage pipe
in the Polish sector. He was 23 years old
when he died.
