[LAB] Hardly anything is known about the background and family of Sir Leon Radzinowicz or about his period of intensive academic activity in Poland between 1929 and 1938. Moreover, in his academic autobiography, entitled Adventures in Criminology, Radzinowicz is imprecise about details. This concerns both the dates of various events, notably that of his obtaining a doctoral diploma from the Jagiellonian University (Kraków, Poland) and his arriving in Poland from Geneva, and the names of various people cropping up in his biography. Similarly, the interesting works of Radzinowicz (until 1935, Rabinowicz) from his ‘Polish period’ are hardly known worldwide outside of a narrow circle.
