Theodoros Stamos (American/Greek, 1922–1997) became known as one of the youngest of the group of Abstract Expressionists working in New York in the 1940s and 1950s. Stamos was born in New York, into a family of Greek immigrants. After studying at the American Artists School in the 1930s, his artistic style developed in the late 1940s to incorporate muted colors and organic shapes, an aesthetic he would maintain for the majority of his life. In the late 1980s, Stamos began painting his surfaces thick with paint, and his geometric shapes increasingly resembled abstract compositions. Stamos participated in the 1945 Whitney Biennial, and in 1946 the Museum of Modern Art acquired one of his paintings. The Museum also included his work in the landmark exhibition, The New American Painting, which introduced Abstract Expressionism to European audiences in 1958. Between the late 1940s and the 1990s, he exhibited regularly in New York. Stamos, who lived in New York and on the island of Lefkada, Greece, died in 1997 at the age of 74.
