Given name: Jankiel Family name: Gruszka

After the liquidation of the Small Ghetto Wladka shared a flat at Nowolipie Street No. 69 with him and three other friends, they were active in the underground Zukunft committee. He was employed in brush factory. Jankiel was deported to Treblinka after the round-up at Mila Street.

He was completely dedicated to the Case, a socialist, idealist, he was not bothered with prosaic or personal issues, he was liked for his cordiality and helpfulness. 'Deportation' drove him to depression- he was not used to taking care of his own interests and it was necessary to struggle to survive.
