Jack was in the Polish army when the war broke out.  He was eighteen years old.  When he came back from the army, he was in a kibbutz in Poland.  He hoped he would be able someday to go to Israel.  He was married in 1940 to woman named Golda.  

He worked for an electrical company as an electrician.  This was his luck that helped him to survive, being an electrician for the Germans.  However he always felt a great sense of guilt because the Germans forced him to make electric barbed wire used in the concentration camps.  
He endured four labor camps in Poland and Auschwitz before escaping in 1945. 

Jack owned his own electrical business in Germany before immigrating to the United States.  He married Esther Kenofsky and they had three children.  

He was a devoted volunteer at the Holocaust Memorial Center.  He used his skills as an electrician for the Holocaust Memorial Center.  He put in new fixtures, repaired old ones, corrected wiring problems, and installed new exhibits.  He furnished all of the electrical supplies himself.

Try your hardest to strengthen our own Jewish homeland, the state of Israel.
