Koula Marangopoulou studied at the Athens School of Fine Arts under P. Μathiopoulos; she also attended courses for one year at the school of painting run by P. Vyzantios and A. Stylou-Diamantopoulou. Yet, the most formative period for her personal style was when she worked with Giorgos Bouzianis (in the 1940s). This experience left an indelible mark on her abstract painting – works in an expressionist vein, including genre scenes and landscapes, still life paintings and portraits.
