Daum (Nancy 1878 -). Foundation of Daum “Verrerie de Nancy” by Jean Daum. The factory initially produced traditional use glass decorated with gold decorations, from 1891 the company switched to producing ornamental glass in the Art Nouveau style following the example of Gallé and the “École de Nancy” that Gallé founded in 1901. Daum quickly developed into one of the most important forces within the Art Nouveau movement, and in 1904 the factory was the leader in decorative glass. Near Nancy, Daum opened a new factory in 1925: “Verreries de Belle Etoile”. Here, mainly use glass was manufactured, the most of which was intended for the American market. Pierre d’Avesn (1901-1990) became artistic director. In 1932 this factory closed due to the general economic crisis. Between 1915 and 1939, Daum also used the signatures : “Moda”, “Mado” and “Maud”, alongside the familiar signatures.
