Hans Harald Rath (1904–1968) led the Viennese glass firm J. & L. Lobmeyr through a period of post-war rebuilding and design change. He joined the family business in 1924 and took over its management in 1938. His work ranged from table glass to experimental lighting and large chandeliers. Today, he is best known for Lobmeyr’s Alpha drinking set and the starburst chandeliers at New York’s Metropolitan Opera. (Lobmeyr)
Hans Harald Rath and the Lobmeyr Family Firm
Rath entered the business founded by his family in Vienna in 1924. Soon after, he helped present Lobmeyr’s work at the 1925 Paris applied arts exhibition. He also maintained ties with artists and the Vienna School of Arts and Crafts. In 1938, he took over the company from his father.
That change came during a period of political upheaval. Lobmeyr’s history records major chandelier orders from Berlin in 1938 and says Rath continued to secure orders during the war. These facts place the firm’s work within the period, but they do not establish Rath’s personal political views. After the war, he helped rebuild Austrian glassmaking. (Lobmeyr history; Lanzinger’s study of the Lobmeyr archives)
Rath’s work followed an earlier Viennese tradition of collaboration between designers and specialist glassmakers. For example, Otto Prutscher designed glass for Lobmeyr in the early twentieth century. Rath continued that close exchange between design and production in a new era.
Rebuilding Austrian Glassmaking After the War
The war disrupted Lobmeyr’s access to Bohemian glass production. In 1947, Rath helped establish the glassmaking school at Kramsach and glass factories in Bad Ischl, Salzburg, and Kufstein. These efforts supported the industry’s recovery and created work for glassmakers and teachers displaced from northern Bohemia. The workshops had moved to Swarovski in Wattens in 1944, where Lobmeyr began making chandeliers with rhinestone glass.
Rath also explored new ways to use light. He worked with Philips in Eindhoven on chandeliers using Linestra and neon tubes. These projects show his interest in lighting as more than ornament. They joined glass craft with new electrical forms and materials. (Lobmeyr)
These initiatives connected design with training and production. The Kramsach school helped pass on glassmaking skills, while factories in Bad Ischl, Salzburg, and Kufstein supported the industry’s recovery. The workshop move to Wattens also brought Lobmeyr into contact with Swarovski’s rhinestone glass expertise. Rath’s later trials with Linestra and neon broadened the firm’s lighting work beyond crystal chandeliers. Philips’s headquarters in Eindhoven and Vienna’s ORF broadcasting centre used these technologies. Together, these projects show how Rath worked across workshops, companies, and public architecture. (Lobmeyr)
Hans Harald Rath’s Chandeliers for Public Buildings
Rath designed lighting for theatres, government buildings, churches, cafés, and other public spaces. In 1955, he worked with architect Erich Boltenstern on the ring chandelier and wall sconces for the reconstructed Vienna State Opera. The project brought crystal lighting into a major post-war architectural setting. (Lobmeyr, Vienna State Opera)
In 1964, Lobmeyr supplied modernist chandeliers for the Luxembourg theatre. Rath also worked with architect Wallace K. Harrison on lighting for the Metropolitan Opera in New York. The opera opened in 1966 with twelve chandeliers designed by Rath. Austria gave them to the United States as a formal gift. Their radiating forms suggested stars or distant galaxies, linking the design to the era’s interest in space. (Lobmeyr, Metropolitan Opera)
The Met chandeliers became a defining example of Rath’s work. They also show how he handled a large commission: he collaborated with the architect, designed for a specific building, and used glass and light to shape the audience’s experience.
The Alpha Drinking Set
Rath’s best-known tableware design is the Alpha drinking set, which he created in 1952. Its glasses stack for storage, giving the set a practical feature as well as a clear, sculptural form. Lobmeyr traces the design’s inspiration to a Baroque copper cup in Vienna’s Museum of Applied Arts. That object, in turn, drew on Islamic works. (Lobmeyr, Alpha set)
The set reflects Rath’s interest in everyday use. Its design makes a group of glasses easy to store while keeping the shape distinctive. Lobmeyr still produces Alpha, and the company notes that the design received the German “Gute Form” design prize in 1964. It remains a lasting example of mid-century glassware that balances function with formal character. (Lobmeyr, Alpha set)

Legacy
Rath died in an accident at Langenzersdorf railway station on 18 November 1968. His sons took over the firm after his death. His legacy rests on both objects and institutions: the Alpha set, major public lighting projects, and his work to restore Austrian glass production after the war. (Lobmeyr)
His career shows how a designer could move between tableware, industrial collaboration, and architecture. Rath worked with glass as a material for daily use, but also as a way to shape public interiors. The Metropolitan Opera chandeliers made that ambition visible on a grand scale.
