Hugo Thiemann

There, he was assistant to Professor Fritz Fischer (physicist), known as the inventor of the Eidophor large-screen video projection system, at the Institute of Technical Physics.

After leaving academia, Thiemann was instrumental in industrializing and commercializing Eidophor while working for GRETAG, the successor company to Edgar Gretener AG.

After a lecture explaining the physics underlying the Eidophor system, Robert Oppenheimer offered him a position at the Institute for Advanced Study (IAS) in Princeton, NJ.

He established the Rive Reine Conference, an annual gathering of Nestlé's top management with guests from industry, politics and finance.

Among the new product sectors proposed by Thiemann was drinking water purification and distribution as well as the concept of Nespresso for ready-made premium coffee.
