He went to school in Pretoria. He studied Electrical Engineering at the University of the Witwatersrand in Johannesburg.
Lazar joined the South African Brigade during World War 2 and was stationed in Italy. His squadron was involved in aerial photography and was the first to get actual proof of the existence of Nazi concentration death camps.
While he was there he did much to help Jews in refugee camps on their way to Palestine. In one of the refugee camps in Italy he met his future wife, Hanna from Rasein in Lithuania. After the war, he brought her to South Africa, first to Mooiplaas and then to Pretoria.

Lazar worked until retirement for Urdan, a steel producer in Netanya, as the Chief Technology officer.
All his life, he was a very active volunteer in organizations such as Rotary and Akim, becoming the president of the Netanya branches of these organizations. He was heavily involved in helping new immigrants becoming absorbed into Israeli life. Upon his retirement, he was awarded the Netanya “ Key of the town” in acknowledgement of all the above activities.
One of the things Lazar will always be remembered for, was his incessant effort to keep in touch and visit all different members of the Judelman clan in Israel and to build a family tree which was the basis for the family tree we have today.
