Wilhelm Teuwen (1908–1967) was a German artist best known for his stained glass work.^[1]

Teuwen was born on 16 August 1908 in Anrath and since 1923 studied at the art school in Krefeld. After graduation in 1929, he enrolled to Kunstakademie Düsseldorf. He studied there with Heinrich Campendonk and, after in 1933 Campendonk has been fired by the Nazis, with Heinrich Nauen, graduating in 1934. In Krefeld, he also met Johan Thorn Prikker, one of the pioneers of the modern stain glass, and this had an important influence on Teuwen's art.^[1]

In the end of the 1920s, the main medium used by Teuwen was woodcut, and he made prints in the style of German expressionism, but then he moved to stained glass. In 1932, he made his first big stain glass, the memorial to the fallen soldiers in WWI in Uedem. In 1937, he carried out the projects for the St. Remigius Church in Wittlaer and the Holy Cross Chapel in Vennheide.^[1]

In November 1946, Teuwen was asked to join the faculty of the Kölner Werkschulen, and till 1967 he taught there classes of stained glass. At the same time, he got many orders to replace glass windows in the Lowe Rhine area which were destroyed during WWII, both in churches and in civil buildings. In particular, he designed windows for Cologne Cathedral and St. Gereon's Basilica. In the 1950s, Teuwen, still busy with stained glass, returned to painting and woodcut. His work of this decade demonstrates increasing influence of Italian Renaissance, most notably Michelangelo.^[1]
