The „Eötvös 175” will start soon

The 175th anniversary of the birth of Baron Roland Eötvös (in Hungarian: Loránd; Buda, July 27, 1848 – Budapest, April 8, 1919), the world-renowned scientist, whose works are still influential today; professor, scientific organizer, statesman and youth educator takes place in 2023. On this occasion a number of commemorative events will be organized by a wide spectra of institutions, associations and civil organizations. The series of events in 2023 can be interpreted as an extension of the „Eötvös 100”, a commemorative year held four years ago, on the occasion of the centenary of his death, in joint commemoration with UNESCO. A number of additional results of the Eötvös 100 became visible only recently. The inauguration of the Eötvös statue in Budapest-Hegyvidék, for example, could only take place one and a half years later than planned, because of the COVID restrictions. In frames of the Eötvös 175, all partners will participate from their own financial resources. All planned events will be published the extended Eötvös 100 website.

You can find information about scientific, educational, sports and cultural events in the constantly updated Event Calendar ( The series of commemorative events starts before his summer birthday (with tourist and sports events in and around Budapest, and an exhibition of the famous Eötvös balance at the General Assembly of the International Union of Geodesy and Geophysics in Berlin, and culminates at the end of September, on the anniversary of the 1906 international scientific conference (Internationale Erdmessung), took place in the Palace of the Hungarian Academy of Sciences. This conference and a related field experiment around Arad launched Eötvös as geophysicist towards world fame.

As every year, a lay wreath ceremony at the grave of Eötvös in the Fiumei út cemetery will be organized by the Association of Hungarian Geophysicists. This year it begins at 11 a.m. on April 6.

The statue of Roland Eötvös in Budapest: inaugurated

The statue of Roland Eötvös in Budapest: inaugurated

The statue of the famous scientist (physicist, Earth scientist) and cultural politician Loránd (Roland) Eötvös (1848–1919), was inaugurated on October 5, 2021, Tuesday in Budapest-Hegyvidék (District XII).

The inauguration of the work of the Kossuth Prize-winning sculptor Tibor Rieger, originally planned for November 2020 (thus the closing of the Eötvös 100 Commemorative Year), took place, due to the COVID situation nearly one year later.

The legacy of Roland Eötvös and his generation teaches us the right orientation in both culture and science – this is the message of the leaders of the institutions and non-governmental organizations who appeared in the Gesztenyés Garden. The inauguration was held in presence of more than one hundred people, admirers of the Eötvös oeuvre.

Roland Eötvös statue in Budapest

The statue of Baron Eötvös Loránd has been set up in the Gesztenyés kert ("Chestnut Garden") of Budapest XIIth district.
The creator is Tibor Rieger, a Kossuth Prize-winning sculptor.
It is a great reassurance for us that after such a long and struggling period, the statue has finally been realized. But the fate of this statue seems to significantly extend the Eötvös 100 Commemorative Year. We believe that the commemoration year will formally end with the inauguration ceremony.
The inauguration ceremony (had been planned to be held on November 17, 2020) is postponed indefinitely due to the COVID-19 situation.

Release of the volume of poems written and translated by Roland Eötvös (1848-1919), and further 2020 follow-ups of the Roland Eötvös Commemorative Year

The Roland Eötvös Commemorative Year officially ended in 2019, but there are still some Eötvös 100 follow-up events that are worth reporting on. For example, a collection of poems and literary translations made by Roland Eötvös in his half-childhood has been published. It will be presented on October 15, 2020 in the conference room of the Library of the Hungarian Academy of Sciences. The Invitation Card is available in Hungarian language. A list of events and publications in 2020 as post-effects of the Eötvös 100 Commemorative Year is given, too.


Roland Eötvös in Heidelberg

On February 10, 2020, the European Physical Society announced that Dutch historian of science Dr. Henk Kubbinga has located a small set of documents related to Baron Roland Eötvös’s doctorate in physics at the archives of Ruprecht-Karls-University in Heidelberg (
The documents will be published by the Library and Information Centre of the Hungarian Academy of Sciences in its electronic repository ( The most interesting piece of the set is a handwritten autobiography of Roland Eötvös in Latin, which will also be made available in a Hungarian translation by Gábor Tóth, librarian at the Library’s Department of Manuscripts and Rare Books. This is not the only result of last year’s Eötvös 100 project. Member of the Leibniz Society and honorary member of the Hungarian Academy of Sciences Hainz Kautzleben recently assessed the scientific achievements of Eötvös ( ) and a memorial to Eötvös is soon to be erected in South Tyrol.

Eötvös 100 events in early September

On September 6, an "Eötvös Loránd Cycling Expedition" starts from Székesfehérvár to Misurina Lake (Dolomites, Italy). The Eötvös Peak (Cima di Eötvös) rises here. The bicyclists, in organization of the ELTE-BEAC Polythlon Club will hand over the imaginary baton to the climbers of the Hungarian Tourist Association (MTE) on September 8. Tourists of MTE will also unveil a memorial plaque and visit the Eötvös Exhibition in Toblach.

At the Kiscell Museum in Budapest, on September 8, visitors have possibility to watch stereo slides made by Roland Eötvös.

On September 9, in the afternoon of opening ceremony of the scholar year of the Eötvös Collegium, there will be a joint event with the École Normale Supérieure and Scuola Normale Superiore. At 5 pm in the Rose Garden the garden pond here and that at the École Normale Supérieure will be symbolically connected. A monograph on the institution founded by Loránd Eötvös will also be launched.

Triannual Meeting of the Eötvös Loránd Physical Society (Sopron, 21-24 August 2019)

At the triannual meeting of Eötvös Loránd Physical Society (Sopron, 21-24 August 2019) three plenary lectures were devoted directly on the life and work of Roland Eötvös (Jenő Sólyom: Loránd Eötvös the man, József Cserti: Loránd Eötvös the physicist, Viktor Wesztergom: Loránd Eötvös the geophysicist). In addition, several scientific and educational lectures were also connected to the Eötvös heritage. The story of re-measuring the famous Eötvös experiment (or after the co-authors: Eötvös, Pekár and Fekete the EPF experiment) was told by academician Lajos Völgyesi, and the first results were reported by Gyula Tóth. Researchers at MTA Wigner FK and BME have been able to reduce measurement uncertainty by an order of magnitude (from 10-9 to 10-10) thanks to the ideal location and automation of the instrument. At this meeting the physicists also commemorated the 150th anniversary of the Mendeleev periodic table. As the session chairman (András Patkós) pointed out, that time many experts could have been able to compile the periodic system of elements, but what Eötvös realized did not have any precedence. His work and results still have been admired by the world of physicists.
