Ioannis Doukas enrolled at the School of Fine Art, Athens in 1859 and continued his studies at The Royal Academy of Fine Arts, Munich in the studio of Karl Theodor von Piloty between 1865-1868. He then moved to Paris to study with Jean Leon Gerome.

In the years that followed Doukas resided in Paris, then Marseille and finally in Vienna where he stayed for six years and was established as an important portrait painter.

In 1876 he returned to Athens where he worked mainly on portrait painting creating a name of one of the most important portrait painters of the 19th century. He had the ability to create the background in a picture without depriving the figure of its luminosity.

In addition to portrait, Doukas also painted historical, mythological, biblical and allegorical scenes. He is one of the main representatives of the ‘Munich School’.

Doukas held a number of solo exhibitions in Athens and participated in a number of international group exhibitions such as the 1869 Exposition des Artistes Vivants in Paris.

His work is found in many public and private collections, notably: The National Gallery, Athens, The Athens Municipal Gallery, The Leventis Gallery, Nicosia, The Averoff Gallery, The Koutlides Collection and The National Bank of Greece collection.

His work also includes important results in the Conformal Representations and in the Theory of Boundary Correspondence. In 1909, he pioneered the Axiomatic Formulation of Thermodynamics along a purely geometrical approach.
