Writer, publicist, editor, painter and decorator, author of stained glass and mosaics, one of the most prominent representatives of 20th century Swiss sacred art. He was the son of the painter Karolina Stryjeńska (1846-1913). He studied at the School of Fine Arts in Geneva and at the Académie Julian in Paris. The impetus for his career as a stained glass artist came from the compositions of Joseph Mehoffer (1869-1946) in Fribourg. Cingria was an animator and founder of the Group of Saint Luke (Groupe de Saint-Luc) - a grouping of artists specialising in high-class overall decoration ensembles for church interiors - from architecture, painting, mosaics, stained glass, sculpture to liturgical vestments, vessels or liturgical book bindings - active between 1920 and 1945. His stained glass can be found in the Basilica of the Blessed Virgin Mary in Geneva, the Church of the Holy Cross in Carouge or the Church of St Francis in Lausanne, among others. A Polish accent can be found in the preface to Stanislaw Liberk's book Les Polonais au Pays de Vaud (1943).
