Lambovitiadis was born to a Greek family in the village of Dhuvjan, Ottoman Empire, today in southern Albania.
After finishing ground-level studies at his home village he moved to Corfu, Greece.
[1] In 1940, during World War II, Lambovitiadis organized Greek resistance groups in his home region Gjirokaster and in nearby Delvinë.
Lambovitiadis campaigned against post-war incorporation of Northern Epirus to Albania and protested against machinations of the agents of the Albanian communist party.
As a result, Lambovitiadis, together with other Greek activists, were considered "enemy of the state" and arrested.
