Catriel Efrony was born in Vienna, Austria in 1923. When the Nazis came to power, he immigrated to Israel where he become one of the founders of Kibbutz Gesher in the Jordan Valley. He studied art with Streichman at the Avni Institute of art in Tel Aviv. Following that, he spent three years in South America, studying at the Bellas Artes in Rio de Janeiro, and underwent a further period of training in Paris. His style has undergone a gradual metamorphosis over the years - from lyrical abstractionism to a more figurative expressionism. (http://catrielefrony.blogspot.com/)
