Unwyd y plant â'u modryb, a gafodd loches yn y DU, lle mae'r Dr Stern wedi byw byth oddi ar hynny. Daeth yn imiwnolegydd ac yn arbenigwr mewn asthma. Ac yntau bellach yn 80, mae'n rhoi o'i amser i hyrwyddo addysg a goddefgarwch.
The children were united with their aunt, who had found refuge in the UK, where Dr Stern has lived ever since. He became an immunologist and an expert in asthma. Now 80, he devotes his time to promoting education and tolerance.
