Summary Kazimierz Prószynski grew up in an intelligentsia family with strong patriotic traditions. As a thirteen-year-old, together with his friend Mieczyslaw Karlowicz, later a composer, he organized performances using mirrors and dim lamps. During his first year of studies in Belgium, he constructed a camera for photos and film projections, which he called a pleograph. He also developed many other cinematographic cameras and film cameras. He invented a system for moving the photosensitive tape, which revolutionized the recording of moving images and the film industry. He recorded the coronation of King George V in London with the first hand-held film camera with image stabilization (aeroscope), which he constructed himself. During the occupation, he took up conspiratorial activities. During the Warsaw Uprising he was arrested by the Gestapo. He died at the age of 70 in the Mauthausen-Gusen camp.
