Josef Albers is not only regarded as one of the most distinguished artists of the twentieth century, but as a teacher and master at the Bauhaus and later at Black Mountain College, he had a decisive influence on the work and style of these famous art schools. He is also one of the most accomplished thinkers in his field and made a name for himself as an art theorist. His last major lecture series took him to Trinity College in Hartford, Connecticut, in 1965. His lectures reflect all of his life and creative experiences. At the same time, they represent the quintessence of his decades-long examination of sight as an artistic process of perception. The very unique idealism that resounds in his work has lost nothing of its topicality and fascination today. It is high time for this text to be accessible in a German translation. In this way, the creative power and thinking of this exceptional artist can be experienced first hand. JOSEF ALBERS (1888-1976) studied and taught at the Bauhaus in Weimar and Dessau. Under Ludwig Mies van der Rohe, he was also deputy director of the art school. After fleeing to the USA, he taught at Black Mountain College and Yale University.
