Robert Pansart (1909–1973) was a French glass artist and decorator renowned for his mastery of refined techniques such as verre églomisé, engraving, patination, and gilding. Trained at the École des Arts et Métiers, he began his career in the workshop of master glassmaker Schwartz, whose practice he later succeeded. From the 1930s onward, he collaborated with prominent decorators and metalworkers, developing a distinctive language that combined technical virtuosity with decorative imagination. His work ranged from mirrors adorned with delicate arabesques to monumental panels of oxidized, silvered, or gilded glass, which became a hallmark of postwar interiors and public spaces.

Among his major achievements are the panel Les Sept Péchés Capitaux (The Seven Deadly Sins) created in 1949, monumental decorations for the Berlitz cinema in Paris and the theater in Poitiers, as well as decorative ensembles for the performance hall of the ocean liner France. Precious yet dramatic, his creations reveal a deep fascination with light and material. Today they remain highly sought after by collectors, confirming his importance in the history of French glassmaking and decorative arts of the 20th century.
