Christos Kapralos was born in 1909 in Panaitolio, a village close to the city of Agrinio.

In 1930 he enrolled at The School of Fine Arts, Athens in the workshop of Oumbertos Argyros, on a scholarship from the Papastratos brothers, who were major benefactors in Agrinio, graduating in 1934. He continued his studies in Paris between 1934 and 1940 at the academies of Grand Chaumiere and Colarossi, mostly in the workshop of the sculptor M. Gimond.

On the outbreak of World War II, Kapralos returns to Greece to fight for his country. After the defeat of the Greek front he returns to his home village where he stayed until 1946. During these years he produced some of the finest of his early works in plaster, using as his models, close friends and relatives, other villagers but mainly his mother.

In 1962 he represented Greece in the international Venice Biennale exhibition, an important landmark in his career, where his work received high praise in the international press and commissions followed worldwide. Throughout his lifetime he worked in gypsum, wood, sandstone, stone, marble and bronze.

In 1991 he established the Christos and Souli Kapralos Foundation where he left a collection of approximately 7500 works to the Greek Nation, including other than sculpture, sketches, paintings, terracotta and ceramic pieces. These are exhibited at the Chistos Kapralos Museum, in his workshop/home in Aegina.

His work can be found in many public and private collections in Greece and internationally. Notably at The National Gallery Greece, The Municipal Gallery of Athens and the Chistos Kapralos Museum in Aegina.
