Esther Rantzen talks to Professor Hyman Levy.
A hundred years ago a carpenter called Marcus Levy escaped from the Russian Tsar by swimming across a river which divided Lithuania from Poland. He arrived in England with a piece of paper in his pocket marked: 'I I want to go to Edinburgh.' There he worked as a street-seller of sponges and came home to discuss the works of Spinoza and Maimonides.
One of his eight children, Hymie, later became Professor of Mathematics and Dean of the Royal College of Science. Now aged 82, he looks back, in the first of four programmes, with a sense of humour and intellect as bright as ever, on his family, his street battles, and his first day at school.
