Sculptor Elizabeth Catlett

Elizabeth Catlett (1915-2012) was an African-American graphic artist and sculptor. Along her long career, spanning more than 70 years, she created sculptures that celebrate the heroic strength and endurance of African-American and Mexican working-class women. Her work is a mixture of abstract and figurative in the modernist tradition with simple, clear shapes. She worked in wood, stone, bronze or clay.  The main purpose of her work is to convey social messages rather than pure aesthetics and that's way I love her. Her work talked about themes such as social injustice, human codition, women or motherhood. Her hardy laborers and mothers radiate power and calm at the same time.
