Östen Kristiansson (often with his brother Uno) was a Swedish designer and craftsman active in the mid‑20th century. He is best known for his work with Luxus, designing functional and stylish Scandinavian modern lamps, including the famous “Tulpan” (Tulip) lamp. His designs typically combine clean lines, wood and opaline glass, reflecting the elegance of 1950s‑60s Swedish design.
