The GDNÄ mourns the death of its former president

The former President of the Society of German Natural Scientists and Physicians (GDNÄ), the physicist Prof. Dr. Harald Fritzsch, passed away in Munich on 16 August 2022 at the age of 79. Harald Fritzsch was President of the GDNÄ in 2003 to 2004 and chaired the 123rd Assembly in Passau.

“Harald Fritzsch was a theoretical physicist who made important contributions to the theory of quarks”, says GDNÄ President Professor Martin Lohse. “He also made a name for himself as an author of popular science books, for example with his book ‘Quarks’, which appeared in 1981. In his later works, he had scientists from different eras discuss difficult physics topics with each other.”

Harald Fritzsch was born in Zwickau in 1943. After graduating from the Gerhart Hauptmann extended secondary school, he was a soldier in the GDR’s National People’s Army in Kamenz from the summer of 1961, where he trained with the air force. He studied physics in Leipzig from 1963 to 1968. In 1968, he and a friend were the initiators of a risky, extremely high-profile protest action against the demolition of the 700-year-old Paulinerkirche. Fritzsch and his friend managed a daring escape by folding boat across the Black Sea to Turkey. He continued his studies in Munich, where he received his doctorate in 1971 under the guidance of Heinrich Mitter with a thesis “On the algebraic structure of observables in the strong interaction”. After his doctorate, he went to the European Research Centre CERN near Geneva for a year. He then moved with Murray Gell-Mann to the California Institute of Technology (Caltech) in Pasadena. From 1977 to 1978 he was a professor at the University of Wuppertal. In 1979 Fritzsch moved to the University of Bern, then in 1980 to the Ludwig Maximilians University of Munich. He became emeritus professor in 2008. Fritzsch was a full member of the Berlin-Brandenburg Academy of Sciences.

The GDNÄ will honour the memory of its former president, the renowned physicist Professor Harald Fritzsch.

Commemorative publication for the GDNÄ anniversary

Commemorative publication for the GDNÄ anniversary

200 eventful years on 200 pages

A lavishly designed commemorative publication in the style of a modern non-fiction book will be available from beginning of September 2022, just in time for the anniversary meeting in Leipzig. On two hundred pages it deals with the eventful history of the GDNÄ, its present range of tasks and the perspectives for the future.

The richly illustrated book sketches the path of the GDNÄ through two centuries. It stops at important stations, looks far into the future, and lets research spark. Then, for example, when renowned scientists, including many GDNÄ members, give inspiring and comprehensible accounts of their own research and the development of the field. These “workshop reports” deal, for example, with an expedition to the deep sea, the search for dark matter, new techniques of energy storage and the history of modern climate research. Also exciting to read are the interviews with a pioneer of the new RNA medicine and the Nobel Prize winner who was honored for the invention of organic catalysis.

Greetings from politicians and scientists introduce the festschrift. The book is rounded off with a multifaceted outlook into the future.

Editor and co-author of the commemorative publication is Professor Martin Lohse, President of the GDNÄ. The work was designed by Thomas Liebscher, graduate graphic designer, founder and owner of the Leipzig publishing house Passage-Verlag. Here are some sample pages:

A society with history(s)

United in advancing the sciences, in open discussion and a friendly atmosphere – that was what the group around Lorenz Oken wanted when they founded the Society of German Naturalists and Physicians (GDNÄ) in Leipzig in 1822. Initially ridiculed as a “scientific nomadic horde,” the research society quickly developed into a meeting place for Europe’s scientific and medical elite. To this day, the GDNÄ remains committed to its core concerns –interdisciplinary exchange, dialogue with society and the promotion of young scientists.

The book contains contributions by Christiane Angermann, Marie-Luise Beck, Lilo Berg, Rainer Blatt, Matthias Bochtler, Angelika Brandt, Dietrich von Engelhardt, Georg Ertl, Jörg Hacker, Günther Hasinger, Heribert Hofer, Robert Huber, Sandra Kumm, Benjamin List, Martin Lohse, Thomas Lohse, Jochem Marotzke, Ansgar Schanbacher, Robert Schlögl, Jörg Vogel, Wolfgang Wahlster, Ernst-Ludwig Winnacker, Ekkehard Winter and many others.

Michael Dröscher: “Bringing people together, developing ideas”

“Bringing people together, developing ideas”

He was an innovation manager in the chemical industry and now keeps the Society of German Natural Scientists and Physicians on its toes: Michael Dröscher on his plans for the GDNÄ of the future. 

Professor Dröscher, you have been Secretary General since 2015 and a member of the Board and Treasurer of the Society of German Natural Scientists and Physicians since 2017. What is its greatest treasure?
Clearly the people who are close to our society. I include our members and all those who take an interest in us and contribute to our activities, for example by giving talks at our meetings. A great treasure is also the student programme, which gives us wonderful access to young people. Of course, we hope to attract even more people from science, society, and schools to become members. This is not easy these days. 

Why is that?
Most associations are losing members and don’t have enough new blood. The GDNÄ, which is also organised as an association, is no exception. Fortunately, we are very generously supported by foundations, so our existence does not depend solely on membership fees. We do not simply accept the decline but do our utmost to fight it. 

How can we do that?
First, we involve young people more than in the past, for example with our own formats at our meetings. For example, at the start of the 200th anniversary celebrations in Leipzig, schoolchildren will organise a part of the programme under the motto “We only have one Earth”. Second, we want to activate our members more strongly, we still see a lot of potential there. As soon as the Corona situation allows, there will also be regional presence meetings again. We introduced this new format before the pandemic and hope to be able to invite our members again soon to exchange ideas with them across disciplines. 

Is the interdisciplinary approach of the GDNÄ still up to date in view of ever greater specialisation in the natural sciences?
Both are important, but the importance of the interdisciplinarity is growing. Let us take my field, chemistry. There is still the classical synthesis of molecules and the development and optimisation of processes. But the great advances occur where chemists work together with biologists and computer scientists. In the GDNÄ we want to inspire this, at our meetings and in between at the regional meetings. I see an enormous need here that is not met by any other scientific society. The personal exchange about new findings in biology, chemistry, physics, computer science, engineering, and medicine without direct pressure to exploit them and with leading experts – that is a great opportunity for the GDNÄ.

Is this only about basic research or also about applied knowledge?
Both should play a role. However, applied research is often neglected in public discourse as well as within the GDNÄ. It deserves more attention.  

You know both worlds and, after professional beginnings in academia, you moved to industry. In 1982 you started your industrial career at Chemische Werke Hüls AG, a company that no longer exists. How did you experience the structural change in the German chemical industry?
This change began soon after I joined Hüls AG in the early 1980s with more and more company mergers and start-ups. When you are in the middle of it, it is not always easy. Overall, however, this development was inevitable in order to survive in an increasingly globalised world. Ultimately, the many mergers have made the German chemical industry stronger and more innovative.  One example: the Marl Chemical Park, where I started, is now Evonik’s largest site and is also home to about 25 other chemical companies. 

You worked as an innovation manager for many years. There is a continuous need for creative and at the same time practicable solutions. Do you have a recipe?
Unfortunately, there is no patent remedy. What worked for me was this approach: bring together good people from different company divisions, let them develop their ideas in protected start-up-like structures, so-called project houses, and feed the solutions, as soon as they are close to the market, into the divisions of the parent company. This approach proved successful, for example, with the Hüls subsidiary Creavis, which then became part of Degussa, both of which have since been merged into the Evonik Group.  

Have successful innovations come from this approach?
I think so. At Creavis, for example, we developed biochemical processes for the production of amino acids, in which Evonik is now the world market leader. Very early on, work was done there on functional nanoparticles, which are indispensable in many areas today – just think of the production of microchips and the application in paints and cosmetics.

How do you see the future of Germany as an industrial location?
We are in the middle of a major transformation towards more climate-friendly energy sources and raw materials. The fossil age is coming to an end, and it is clear to industry that it must completely reposition itself. The investments for the next 15 to 30 years are already geared to this. The transformation can succeed if we have enough hydrogen and can reliably obtain it from sun-rich countries. Some countries, such as Saudi Arabia, are preparing for this. As a member of the Enquete Commission on the Future of the Chemical Industry in North Rhine-Westphalia, I have dealt extensively with this topic and continue to advise companies on these issues.  

Much of the public debate is currently about gas as a transitional solution. What is your opinion?
In order to meet the growing energy demand in our country and to replace the coal and nuclear power plants that we have shut down and will shut down in the near future, we cannot do without gas in the foreseeable future. In the future, the chemical industry alone will need as much electricity as all private households together today, and electromobility will need as much again. Gas-fired power plants will probably be needed as a bridging technology for another 15 to 20 years. We also need to build new plants. Evonik is currently building two new gas-fired power plants in the Marl Chemical Park to replace two coal-fired units. In any case, we have to ensure that we can obtain as much gas as we need, whether it comes as liquefied gas by tanker or via the pipelines. If Nord Stream 2 does not come for political reasons, we will need other supply routes.  

Finally, let’s take another look at the GDNÄ, which will soon be 200 years old. How far are you with the preparations for the celebration?
We are right on schedule. With the Leipzig Congress Hall we have found a wonderful venue for the festive assembly in September, the lecture programme with renowned scientists is set and the students will come together in early summer to design their part of the programme. There will be an attractive, generally understandable commemorative publication in book form. We are increasingly addressing the public this time: with media reports, via Twitter and other social media, and with lectures to which all Leipzigers are invited. We attach great importance to the exchange with society – entirely in the spirit of the Year of Science 2022, which aims to strengthen citizen participation in science and research under the motto “Nachgefragt!” – which means both, “Inquired” and “in demand!”.

About the person

Prof. Dr Michael Dröscher has been Treasurer and Board Member of the GDNÄ since 2017 and its Secretary General since 2015. He comes from Kirn on the Nahe, where he was born in 1949. He studied chemistry in Mainz, where he also completed his doctorate.  He then took a position as a scientific assistant at the University of Freiburg and habilitated in macromolecular chemistry at the age of only 31. He continued his academic career first as a Privatdozent and from 1988 as an adjunct professor at the University of Münster.

Even more than basic research, Michael Dröscher is interested in the application of scientific results – and so his path led him to industry. He started in 1982 as a laboratory manager and in 1984 as a department head at Hüls AG in Marl, North Rhine-Westphalia. He was to remain with the chemical company, or rather the successor companies Degussa-Hüls, neue Degussa and Evonik-Industries AG, for 27 years – in changing functions. In 1997, the experienced chemist was appointed managing director of the newly founded Hüls subsidiary Creavis Gesellschaft für Technologie und Innovation mbH; today the company operates under the umbrella of Evonik Industries AG as Evonik Creavis GmbH. Five years later, in 2002, Michael Dröscher became Innovation Manager at Degussa AG, which later became part of Evonik.

Michael Dröscher was also involved in professional societies and professional politics, including as chairman of the German Bunsen Society (2005 to 2006) and from 2020 to 2011 as president of the German Chemical Society and as manager of the CHEMIE.NRW cluster. He holds an honorary doctorate from Kazan National Research Technological University (Russia).

In addition to his duties in the GDNÄ, Michael Dröscher is active in many honorary capacities: as Chairman of the Board of Directors of the Max Planck Institute for Coal Research in Mülheim and as a member of several boards of trustees and advisory boards of institutes of the Max Planck Society, the Leibniz Association and university institutes. He is also a member of the supervisory board of bValue AG, which promotes and co-finances start-ups.

How innovation can revitalise the chemical industry: This is described in a practical way by renowned experts in this book co-edited by Michael Dröscher. Here is a reading sample from the English-language title (ISBN 3-00-012425-X.) © Festel Capital

Martin Lohse Exciting times for science

“Exciting times for science”

Martin Lohse, President of the GDNÄ, invites to the celebration of the 200th anniversary celebration in Leipzig.

Professor Lohse, the GDNÄ will be 200 years old in September 2022. How will this anniversary be celebrated?
200 years: this is really a significant and wonderful anniversary. During these 200 years science has developed in an incredible way, all over the world, but particularly in Germany – and often from within the GDNÄ. We want to celebrate this special anniversary with a very special four-day anniversary conference in September: in the city where the GDNÄ was founded, Leipzig, and in the beautifully modernised Art Deco Congress Hall at the Leipzig Zoo.

Who is invited to this celebratory conference?
All members are cordially invited, plus participants in the student programme and former scholarship holders, as well as the general public for some of the events. We hope that the Federal President, the Prime Minister of Saxony, and the Mayor of Leipzig will honour us with their presence. Leading scientists from Germany and abroad, including Nobel Prize winners, will give lectures and celebrate with us. And aspiring students of science journalism as well as regional and national media will cover the conference.

As the President, you were able to choose the topic of the conference. Why did you choose “Images in Science”?
This topic has a general, but also a very personal component. You will find both aspects in the conference. Images have always conveyed central messages in and from science. Let us think, for example, of the many drawings Alexander von Humboldt made on his travels, of the spectacular photos of the North Pole MOSAiC expedition, or of the fantastic images of the space telescopes. In my own research, fascinating detailed images can be produced with new types of microscopes: images of individual biomolecules and from the innermost parts of cells and organisms. The anniversary conference will bring us up to date in this very broad spectrum of images.

Preparations for the big anniversary are in full swing. Let us take a look behind the scenes!
Preparations for GDNÄ conferences always take well over a year: topics and speakers are discussed and found, conference logistics are planned, a social programme is organised. We started planning for the anniversary conference a good two years ago, because this meeting should be even more beautiful than usual. We have attracted many excellent speakers from all over the world. The conference rooms in the Congress Hall provide a magnificent setting for the meeting, the cooperation with the zoo is very close and committed and offers many highlights, and the social programme will make the meeting particularly delightful.

Let us turn our gaze back once more. 1822 to 2022, that is a long time: how has the GDNÄ managed to last over so many years?
The two centuries of its existence are without doubt the most exciting times science has ever experienced. Never before have the developments in science, but also those that science brought to society, been so great – and this is true for the entire spectrum of the GDNÄ. Many disciplines were actually born during this time, and they have all evolved into their own specific worlds. The GDNÄ has always been at the centre of these developments, and many specialist societies have sprung from the GDNÄ, and have often become much larger than the GDNÄ itself. However, during all these years, the GDNÄ has retained some unique features.

What are these special features?
Three aspects characterise the GDNÄ and make it unique: First, the GDNÄ cultivates interdisciplinary discussions across a broad spectrum of subjects – in a way that cannot take place in specialist societies. Second, the GDNÄ runs a student programme with great potential for the future. And third, the GDNÄ addresses the general public: with its activities in science communication, via its homepage, and invites citizens of the city and its region to its meetings. We will highlight all three aspects in Leipzig.

What will be the role of young people at the Leipzig conference?
We invite more than two hundred young people: Selected high school students from the region, former programme participants, winners of the “Jugend forscht” and “Jugend präsentiert” competitions. There will be preparatory workshops and a presentation of the results at the opening ceremony. The aim will be to define and express young people’s expectations of science. With this programme, which has been organized by Mr Mühlenhoff for many years, we want to address young people and open up paths to science for them. And, of course, also into the GDNÄ. 

The Corona pandemic has shown the importance of the dialogue between science and the public. How has the GDNÄ been involved in this issue?
The Corona pandemic has highlighted both strengths but also weaknesses of our society. The strengths include an incredible number of rapidly produced research results, including, above all, the development of vaccines in less than a year. However, it has also become clear how difficult it is to connect to the entire population, to convey research knowledge. And it has also become clear how much basic knowledge is needed for conversations about the disease and meaningful countermeasures. The GDNÄ aims to provide information about this topic on its homepage, it participated in the discussion about risk-adapted measures at an early stage and, together with science academies and research institutions, aimed to inform politicians. Some of its members participated, for example, in a symposium of the Hamburg Academy of Science on “infections and society”. Together with German science academies, we now want to increasingly devote ourselves to the follow-up and ask address two big questions: How did we as a society and how did science fare in this crisis? And what can we learn from this for the future – for future pandemics and other crises, but also for science communication? 

What role will the Corona pandemic play in the anniversary meeting?
Corona will not be the focus at the Leipzig meeting. So much has already been said about it that it did not seem to make sense to us. But RNA medicine, which has brought us the best vaccines so far and opens up completely new opportunities for innovative therapies, will be a central topic of the “Medicine” session on Sunday morning in Leipzig. 

What are your wishes for the GDNÄ in the coming years?
Of all the wishes I have for the GDNÄ, one is central: that it may continue to play an important role in the dialogue between the sciences, with the public and especially with young people. And that for 200 more years!
