Tobias Grau. After his studies in Munich and New York, Tobias Grau started his career as an interior designer in Hamburg in 1984. It only took three years before he presented his first light collection at the Cologne furniture fair. Lamps and light systems became the central theme of his work. He also designed his own shops, fair stands, his own brand as well as the catalogue. in 1998, the Tobias Grau enterprise moved into a corporate building on the outskirts of Hamburg whose interior design was also designed by himself. From then on he again focused more on interior design, i. e. the creation of holistic office concepts encompassing everything from spatial planning to carpets, furniture and lighting.
