Piet Hein was a Danish scientist, mathematician, philosopher, writer and artist. His studies included theoretical physics and philosophy at the University of Copenhagen and art at several private art schools as well as the Royal Institute of Art in Stockholm. Hein is known for having invented a certain table leg construction meant for the famous "super ellips" table which he designed together with Bruno Mathsson. Thanks to their construction, the table was perceived as both solid and light at the same time and it could also be assembled without tools.
Together with Swedish architect David Helldén, Hein has also designed the plan for the Sergel Square in Stockholm. Hein also operated under the false name Kumbel Kumbell.
