François Morellet was a French contemporary abstract painter, sculptor, and light artist. His early work prefigured minimal art and conceptual art and he played a prominent role in the development of geometrical abstract art and post-conceptual art.
Joseph Wenglein was a German painter who is often referred to as one of the last significant landscape painters of the 19th century Munich school.
Parallel to his law studies Joseph Wenglein studied at the Academy of Fine Arts in Munich. He then switched entirely to art and became a pupil of the landscape painter Johann Gottfried Steffan. On his recommendation, Wenglein sometime later became a pupil of the painter Adolf Heinrich Lier, whose colouristic tendencies, calculated to express profound moods, particularly appealed to him.
Josef Wenglein knew how to reproduce the change of daylight, especially in spring and autumn, with a fine sense of the slightest atmospheric fluctuations and to vary the grey pleasant tone of the Bavarian plateau in all its nuances masterfully.
Otto Piene was a German-American artist specializing in kinetic and technology-based art, often working collaboratively.
