Dear members and friends of the GDNÄ, 

Welcome to the 132nd Assembly and 200th Anniversary of the Society of German Naturalists and Physicians (GDNÄ), the oldest scientific association of its kind in Germany. 

Since 1822, our society has brought together scientists, scholars and those interested in science for interdisciplinary exchange. Today, the GDNÄ is more modern than ever: it promotes dialogue between the natural sciences, medicine, technology and the public. 

We celebrate this at the founding site in Leipzig together with our members, many guests and about 200 pupils and students. From these young people we expect questions and suggestions on the topic “We have only one world”, which they will develop in the run-up to the meeting. The lectures will focus on the significance of images in science: images show new discoveries, explain results, clarify hypotheses. Images can prove and explain – but also suggest and falsify. From hand drawings to computer animation, images accompany science. 

Listen and watch what the latest technologies can produce in terms of images and how our perception and our ideas about the world are shaped by them. But in particular, take part in the exciting discourse about the future with young people. 

As we write this invitation, images of the horrific horrors of the war of aggression against Ukraine are spreading. We feel for those upon whom this war has broken out and to whom this injustice is being done! We do not foresee how this war will develop further – but let us be confident that justice and peace can prevail, and that we will be able to meet in the autumn in a way that unites people and nations.

We look forward to seeing you!

Back to the roots

To celebrate its 200th anniversary, the GDNÄ will return to its founding city of Leipzig from 8 to 11 September 2022. The venue will be the Congress Hall at Leipzig Zoo. The Art Deco building combines historical and modern elements in an elegant interplay. It was inaugurated in 1900 as the “Bürgerliches Gesellschaftshaus” of the zoo. Initiated by a citizens’ initiative, the ensemble was extensively renovated and converted from 2010 to 2015.

The Saxon city looks back on an eventful history. Sorbs settled here as early as the 7th century in the “Ort bei den Linden”. Around 1165, Leipzig was granted city rights and market privileges and quickly became an important trading city. An imperial privilege in 1497 initiated the development of Leipzig into a trade fair city of European standing.

The university, founded in 1409, is one of the oldest in Germany. Today, together with numerous non-university institutes, it makes Leipzig a city of science and research.

Leipzig’s musical heritage is also highly regarded far beyond the city and state borders. Johann Sebastian Bach worked as a cantor in St Thomas’ Church for 27 years. The world-famous St Thomas’ Boys Choir has its home here.

The events of autumn 1989 made the world look to Leipzig. St Nicholas’ Church became the starting point of a peaceful revolution that led to the reunification of Germany. In this so significant church we celebrate the 200th anniversary of our society with an anniversary concert.
