Maria Voudouroglou studied at the School of Fine Arts and participated in the group of young people who, during the Occupation, were guided by Yannis Tsarouchis. Her painting was influenced by reality because her inspiration was what she observed: plants and trees, later landscapes and later the abandoned but beautiful buildings of Old Patras. She was specialized in the illustration of children’s books where she illustrated about fifty in collaboration with a multitude of authors. She had great sensitivity to issues concerning the environment and the destruction that people cause to it. She focused on the detailed depiction of Greek plants and spent decades observing them according to the rules of Phytology.
