Dimitris Letsios was born in 1910 in Anakasia, a village outside Volos. Despite his father’s objections, he gave up school very young to work in the family bakery, where he stayed until his retirement. In his free time, he made excursions into the countryside, which he began photographing after buying a cheap camera in 1934. The people and places seen on those excursions became his principal subjects. During the Occupation, he joined the resistance and at the end of the war was imprisoned and exiled.
Letsios was self-taught, apart from some technical advice from Volos photographer Babis Basdekis.
He was co-founder of the Greek Photography Society in 1952, and was twice president of the Volos Cinema Club.
His photographs have appeared in numerous exhibitions in Volos and elsewhere in Thessaly, and have won awards in Berlin and Bucharest. His work is also the subject of three books and books and a half-hour documentary.
