Born in Kaiserswerth in 1915, Hann Trier completed his studies at the Kunstakademie Düsseldorf and initially worked as a technical draughtsman and stage designer. In 1946, he opened a studio in Bonn and undertook extensive travels to Colombia, Mexico, and New York. During one of his stays, the painter found decisive artistic inspiration in dance, which led him in the mid-1950s to work with both hands and to create the symmetrical structures that became his trademark. This shift in his work was an important liberating impulse for Trier and resulted in the intertwining of gestural movement, painting surface, and colour substance: the brush »dances« on the surface, allowing lines and matter to merge into a single entity. From the late 1950s, Trier taught as a professor at the Hochschule für bildende Künste Hamburg and established additional studios in Tuscany and the Eifel region. The painter died in Castiglione (Tuscany) in 1999. He is known for his wall and ceiling paintings, which can be seen in Charlottenburg Palace in Berlin, the library of Heidelberg University, and the German Embassy residence in Rome, among other sites.
