Born in Bottrop in 1888, Josef Albers began his career as a teacher while also working in glass painting and printmaking. In 1918, he created a stained-glass window for a church in his hometown. After studying in Berlin, Essen and Munich, he entered the Bauhaus in Weimar in 1920 and worked in its glass workshop. In 1923, he began teaching the preliminary course and, in 1925, joined the teaching staff as a Jungmeister. Following the Bauhaus's closure in 1933, he moved to the United States with his wife, Anni, and taught at Black Mountain College in North Carolina, helping to develop its visual arts programme. In 1950, he became chair of the Department of Design at the Yale University School of Art, a position he held until 1958. In 1963, he published Interaction of Color, a seminal study of colour perception and interaction that reflects the theoretical concerns underlying his Homage to the Square and Structural Constellations series.
