Weininger, who left Pécs in the early 1920s, worked together with Marcell Breuer, Alfréd Forbát and Farkas Molnár. It was Weininger who planned the well-known "globe theatre". In Berlin he joined "Der Sturm". He attended the private course of Doesburg in Weimar, then met the Dutch movement of De Stijl founded by Doesburg. Its most important representative was Modrian, who thought that a composition reduced to prime colours and a square was best qualified for expressing "purity, geometric simplicity, regularity, structure and function".
