At this address, "Kitchen" (Kuchnia) the secret kibbutz of the Chaluc organization was housed. It was run a.o. by Zivia (Cywia) Lubetkin and Yitzhak (Icchak) Cukierman.

There was a regular lecture program run at 34 Dzielna street almost every day. Janusz Korczak had a lecture at the kibbutz on January 18, 1942 and Stefa Wilczyńska on January 20, 1942.
