This small catalogue is a very good read! In French and German, this is a comprehensive view of the artist, his works and techniques.
 
After the Vorwort by Stefan Trümpler, director of the Vitromusée Romont, Switzerland and Myriam Wierschowski, director of the Deutsches Glasmalerei-Museum Linnich, Germany, the chapter Weg von der Malerei und Zrück zu Ihr, Holger Brülls explains how Poensgen's figurative painting was transformed from the late 1950s into his graphic and minimalist works of the present. Generous photo material allows readers to follow an explanation of how the German graphic tradition shaped his “drawing-like” glass windows: first with lines and forms. Later, Poensgen discovered the freedom of painting again by using a reversed painting on glass technique. Elisa Ambrosio in the chapter Erlebnis Freiheit, clearly describes the technique's history from the mid 1500's on to include Poensgen's first encounter with the Schlossmuseum Murnau's collection of expressionistic painters Wassily Kandinsky, Gabriele Münter and Franz Marc where Poensgen realised this technique had developed beyond folk art.  He began to practice the thought process required of reversed painting on glass techniques but, on paper, between his commissions for stained glass windows.

After moving to Soest, in 2013 he began to use the reverse painting on glass and in the next chapter, Jochem Poesgen offers his thoughts on his reversed glass panels in Gedanken zu meine Hinterglasbilder, followed with many page-full  photos of his works and a written biography.
 
I warmly recommended this well made document as an artists’s portrait from which we may benefit from his vast inheritance!
