Demosthenes Ligdopoulos was born in Athens, Greece in 1898. At the age of 18, in 1916, he was enrolled at the University as a mathematics student. On the same year, alongside his co-students Sp. Komiotis, Fr. Tzoulatis and Tzoumas brothers, he founded the “Socialist Youth” of Athens. Since then, the socialist ideas and the labor movement became an inseparable part of his life. The Great October Socialist Revolution in 1917 was an event that ignited the flame of Ligdopoulos' revolutionary thinking and activity.
