His apprenticeship began first in Dimitrios Filippotis’s and then Thomas Thomopoulos’s studios. In 1903, he enrolled in the Athens School of Fine Arts and in 1909 he began receiving a monthly subsidy from the Averoff Estate. In 1911-1912, he won the Chryssovergeio Award and in 1914 received a scholarship for international studies, of which he only benefited after 1919 due to the outbreak of World War I. In 1919, he came to Paris and enrolled in the Ecole des Beaux-Arts, studying with Jean Boucher. Returning to Athens in 1923, he established his own studio and in 1925 was appointed Associate Professor of Plastic at the National Technical University of Athens.
He participated in group exhibitions in Greece and other countries, including exhibitions of the Greek Artists Association and the Greek-French exhibition in Athens (1918); a posthumous retrospective show of his work was organised at the Parnassos Hall in 1926. His work was also shown in the 1948 Panhellenic Exhibition in Athens.
Forged mainly during his Paris years, Loukas Doukas’s creative identity clearly suggests influence from Rodin’s sculpture, oscillating between realism and expressionism. His works tell of his strife to capture reality through a selection of realistic subjects or to capitalise on expressive passion through expressionistic distortion.
