[en] A biographical portrait of Bruno Touschek, an Austrian physicist who, before and during the Second World War, went through the dramatic adventures of a non-pure arian young person. Later he worked in Germany, Great Britain and Italy. Touschek was the first to propose chiral symmetry. He was the initiator and main driving force in the early developments of e⁺e^- colliding machines. His wide scientific culture, his ingenuity and enthusiams for any new challenging problem and the search of its solution were essential elements in determining the extraordinary influence Bruno had on the work of his younger colleagues. 'He led an intense and vigorous life and by his example and friendliness helped many colleagues and friends to achieve greater happiness and awareness in their own lives'. (orig.)
