Lenz Klotz worked in Basel from the early 1950s until 2017 and is considered one of the most important representatives of informal painting in Switzerland. The basis of his work is the intensive study of Paul Cézanne, the Cubists, Alberto Giacometti and his teacher Walter Bodmer. Lenz Klotz developed a unique visual language of oscillating lines. While Klotz’s early work was influenced by the formal discipline of Cubism, the geometrically bound formal language soon loosened into freer, seismically motoric-looking line paintings. In the early 1960s, these lines became rhythmically freer, forming two-dimensional geometric figures reminiscent of calligraphy, musical scores, and other lyrical forms of notation.
Lenz Klotz’s works are represented in important collections such as the Kunsthaus Zürich, Switzerland; Aargauer Kunsthaus, Switzerland; Kunstmuseum Basel, Switzerland; Kunstmuseum Luzern, Switzerland.
