The idea for the Denkfest Festival was born in 2009 at a retreat of the Swiss Freethinkers. The goal was to bring scientists on stage, to make their work accessible to the general public and to facilitate a lively exchange.

The first edition took place in September 2011. During these four days, 40 artists, lecturers and panelists performed in front of 420 participants from 15 countries. Speakers and participants agreed that it was an extremely stimulating and enjoyable occasion.
