Since its founding on June 3, 1769, the Society has tried to uphold the ideas of the founder: Steven Hoogendijk and Directors: Salomon de Monchy, Leonard Patyn, Lambert Bicker, Cornelis Nozeman, Martinus Schouten and Jan Daniel Huichelbos van Liender, under the motto: “Certos feret experientia fructus”, loosely translated “Only the experiment bears fruit”.

On June 7, 2019, this legacy was celebrated in the presence of: Her Royal Highness Princess Beatrix of the Netherlands, our Protectrix with – once again for the occasion – the age-old and proven scientific instrument: ‘Competition’ (see video). This anniversary competition: “How can the connection between scientists and the public be improved in an experimental manner” had 22 entries. A jury led by our Praeses Magnificus selected: Burg. Ahmed Aboutaleb, the winner was determined from three finalists.

In addition to the competition, the first copy of the 250th anniversary book: “We have only just begun“, was presented to our Protectrix.

Afterwards there was extensive discussion during a pleasant drink. Historical instruments borrowed from the Teylers Museum were also on display for the occasion and the operation of replicas was explained.

The harmonograph, recreated by students, particularly attracted attention, but Rolf Hut had more in store.

After this, the group moved to the still existing part of the former Stock Exchange building to conclude with a dinner there. Pres. Dir. Han Vrijling gave a fiery lecture why the Industrial Revolution did not start in 18th century Holland and why Economics is also an experimental science, or at least that insight could prevent a lot of problems.
