Nana (whose real name is used here instead of her husband's surname) is still active in the design stage. She has been a close friend of Professor Cucapolo for many years. Like Mr. Ku, she shared the Longning Design Award with her husband who died young at the age of 33. Later, the Leronning Prize ended. Following the Nordic Design Award, two masters were invited to be the first judges. Cukapolo told me that Nana is a typical "heroine among women" and has always kept fresh ideas for half a century. The combination of master temperament and female sensitivity has shaped her into an irreplaceable treasure in the design treasure house of the 20th century.

1944, 19 years old, Nana, who was still studying in an art school, cooperated with her future husband, Jorgen Dietzel, and showed a well-designed room at the Woodworking Association exhibition in Copenhagen that year, which was commented as "modern life in all aspects" by the newspapers at that time. After the war, Denmark's specific requirements for real life made Nana concentrate on studying the interior of the house, and then she was a great success at the Milan World Expo. Her various furniture works have almost become the symbol of new life in Denmark. At the same time, Nana, who is energetic and quick-thinking, has attacked everywhere and won good news in the fields of jewelry design and textile design. In the early 1960s, Nana naturally became one of the core figures in Danish avant-garde design. Like Wiener and Panton, Nana has made extensive attempts on various new materials and technologies and obtained her own unique design results.

Nana's most successful furniture design so far is artistic creation. On the basis of careful selection of materials and careful study of color and geometric composition, furniture that finally looks like pure art can be welcomed by most people, which also makes it easy for Nana to cooperate with the most famous furniture companies in the world. Nana has a natural interest in several geometric features in furniture design: circular arc, annular composition, rhythmic color arrangement and repetition, which makes Nana fascinated by butterflies. She has carefully observed this wonderful animal for many years, trying to capture a sense of relaxation floating in the air from the flight of butterflies, and then applied it to her design, resulting in many wonderful furniture design classics. The most wonderful work is "Butterfly Chair" designed by 1990. Their completely asymmetric superstructure is supported on deformed steel feet, which makes the viewer feel the rhythm of life strongly.

Nana always does things by instinct. In her view, as long as a designer really enters the design state, any result is possible, which is both a challenge and an opportunity. When designing, Nana always goes directly from sketching to making full-scale models, so as to control the real effect. As a hostess with strong artistic temperament, Nana sometimes prefers function to emotion, just as she said: I try all possibilities: technology, materials, form and function, but what I care about most is human emotional factors.
