Valentin Bousch (circa 1490 – August 1541) was a Renaissance stained glass glazier and painter from Strasbourg, active in the Duchy of Lorraine and the Republic of Metz. A rarity among stained glass artists, Bousch is seen as one who actively sought to express new ideas in his art, often before they were widely used in the area, revising his method even from one window to the next,[1] to create striking Renaissance effects and a personal style.[2]
