Josef Albers was a German abstract painter known for his paintings and prints exploring color and geometric shapes. He was born in 1888 and became an art teacher at the influential Bauhaus Art School in Germany. When the Nazis closed the school, Albers fled to the United States. There he developed his signature style of painting squares of different colors to experiment with how colors interacted and made people feel. Albers painted over 1,000 works in his Homage to the Square series before his death in 1976, making him a pioneer of abstract art.
