The fact that this highly topical matter still remains undecided 50 years on demonstrates the far-sightedness of this designer, author, professor, curator and skilled photographer who on May 29 would have celebrated his hundredth birthday. Nelson (1908- 1986) was one of the most influential figures in American design in the second half of the 20th century (many see him as the inventor of American design) and many of his designs (such as the Marshmallow sofa, the Ball clock and Bubble lamp) are now timeless icons. An extensive exhibition (from September 13 until spring 2009) organised by the Vitra Design Museum in Weil am Rhein celebrates his work and thinking. Elena Sommariva
