Theodore Stamos was a Greek-American artist who was part of the “irascible” group that included such notables as Mark Rothko, Willem de Kooning and Jackson Pollock. So he can be considered a pioneer in abstract expressionism and is internationally renown for this; but as usual he is one of those that you don’t hear about. You need to be specifically interested that particular period in art and history.
Theodore’s father was from Lefkás and his mother from Sparta although he was brought up on Manhattan’s lower east side in the USA.
When he visited Lefkás he created a sub series from his Infinity Fields series of paintings. This was from 1970 until his death in 1997. It was expressionistic in style his paintings.
He is honoured on the island by having the Theodore Stamos exhibition hall 
bear his name as well as exhibiting his work. He also has the honour of having a street named after him. Here is the Wikipedia entry on Theodore Stamos.
He is the second part of my Greek painters series:-
Other series include Greek Poets, Authors, Painters, Art, Musicians, Museums, specialist fields of Interest, Conversation, Famous Greeks, Foreigners with an interest in Greece, Greek islands and Rural Villages in Lefkás. All the links can be found here: Series links.
Do you have any artists in your country that you think the world needs to know about?
