Biography Family background and childhood Laron was born on February 7, 1927, to a Jewish family in the Bukovinian city of Cernăuţi (Chernivtsi), then in Romania (now in Ukraine). At the age of 6, he moved with his family to another Bukovinian town, Rădăuți.

There he had the chance to survive as a worker in a factory, which was founded in Mogilev by his uncle, Siegfried Sami Jagendorf (1885–1970), in order to save as many Jewish deportees as possible. Accordingly, Laron became a licensed iron turner.
