Sam Mordoch was a businessman with activities in the fields of insurance, banking and trade. For many years he was the representative for Greece of the well-known German insurance company, Victoria zu Berlin Allgemeine Versicherungs-Actien-Gesellschaft, known as "Victoria Berlin". He was also a shareholder in the Paper Mill of Macedonia, founded in 1936. In 1941, his two sons were enlisted on the Albanian front, so he settled with his family in Athens. In 1943, when persecutions against Jews broke out in the capital, the family was rescued thanks to false papers provided by the police and fled by sea to Turkey and then to the Middle East. After the war, he returned to Athens and became president of the Central Board of Jewish Communities in Greece. Andreas, his youngest son, remembers that in Thessaloniki they lived in a house on the corner of Vasilissis Olgas and Martiou Streets, built in 1905 by the architect Xenophon Paionidis for the Turkish divisional commander Seifulah Pasha and bought by his father around 1930. The family residence, claimed by its members, was sold to the Social Insurance Institute (IKA) and after several adventures it housed for years the Municipal Gallery of Thessaloniki.
