Demetrios ("Dimitris") Pikionis (; 1887–1968) was a Greek architect, and also painter, of the 20th century who had a considerable influence on modern Greek architecture. He was a founding member of the Association of Greek Art Critics, AICA-Hellas, International Association of Art Critics. His oeuvre includes buildings and urban planning in Athens and the entirety of Greece—including several schools and a playground in Filothei, Athens. Life and work He was born in Piraeus to parents of Chiot descent. He inherited his talent in painting from his father, who was had an aptitude in the arts. In 1906, he became the first student of Konstantinos Parthenis, a distinguished Greek painter, while he was studying at the National Technical University of Athens civil engineering, graduating in 1908. He then continued his studies in Paris and Munich, in sculpture and drawing. In Paris, he attended architecture classes at Ecole des Beaux Arts (Paris). Pikionis was back then introduced to the work of Paul Cézanne and became friends with Giorgio de Chirico. Some Greek painters of the time, such as Georgios Bouzianis and Periklis Giannopoulos, were influential figures during these formative years. He returned to Greece and after the Balkan Wars, he started studying and working in architecture during which period, he began shifting his focus on the study of the modern Greek architecture. In 1921, he undertook a lecturer position at the 'Morphology' department at the National Technical University of Athens where he stayed until 1923. In 1925, he received a permanent position in the department of decoration as a professor. Between 1930-1935, he co-published with his good friend, the painter Hadjikyriakos-Ghikas the magazine '3ο Μάτι' (translated as '3rd Eye') where he published many of his texts. The magazine collaborated with many artists and academics, such as Stratis Doukas, Takis Papatsonis, Sokratis Karantinos and others. His first important work was Moraitis house in Tzitzifies (1921-1923). In 1932, upon the completion of the Elementary School in Pefkakia of Lykavittos, he came to the realisation that his works were not satisfactory and changed his aesthetic perceptions. All of his subsequent architectural works were based on the idea of bridging universalism with regionalism. In the 1940s and 1950s, his architectural creation was limited to designs for graves. However, in the following period, from 1951 to 1957, he was involved in many projects. Among them is the formation of the archaeological site around the Acropolis and Philopappou
