Marie-Alain Couturier, O.P., (15 November 1897 – 9 February 1954) was a French Dominican friar and Catholic priest, who gained fame as a designer of stained glass windows. He was noted for his modern inspiration in the field of Sacred art.
Gabriel Loire (April 21, 1904 – December 27, 1996) was a French stained glass artist of the twentieth century whose extensive works, portraying various persons or historical scenes, appear in many venues around the world. He founded the Loire Studio in Chartres, France which continues to produce stained glass windows. Loire was a leader in the modern use of "slab glass" (French: dalle de verre), which is much thicker and stronger than the stained glass technique of the Middle Ages. The figures in his windows are mostly Impressionistic in style.
