Veggos was born in Neo Faliro in May 1927, the only child of Vassilis and Evdokia Veggos. His father, a civil servant, was a resistance hero and after the war was fired from his job at the state electricity company due to his political beliefs and caused severe financial problems for the family, forcing young Thanasis to do various odd jobs to help out.
Thanasis Veggos was also exiled himself from 1948-1950 for political reasons to Makronisos island, where he met director Nikos Koundouros, who was also exiled there and later gave Veggos his debut movie role in Magiki Polis (1955) after playing bit parts since 1952.
He also worked with renowned Greek directors Theodore Angelopoulos and Pantelis Voulgaris.
Veggos usually played the roles of everyday people struggling to make end meet, which endeared him to the Greek public, but also acted on stage in Aristophanes comedies.
In 2000, Veggos survived an accident in which his car crashed into a train, and later did a series of relevant safety advertisements.
In 2008, Veggos was made a Commander of the Order of the Phoenix by Greece's President of the Republic Karolos Papoulias.
He is survived by his wife Asimina and their two children.
