Free Knowledge Award


Knowledge is not always free. Yet assuring this freedom is an indispensable part of a democratic system. As such, Wikipedia has become part of our everyday life. Millions of people read the online encyclopedia daily, thousands work voluntarily on writing, editing and completing articles in almost all languages.

To honour the diverse engagement for a society full of free knowledge, Wikimedia Austria – the local association behind Wikipedia here in Austria – is for the first time giving out the Austrian Award for Free Knowledge. It will be awarded to civil single initiatives and particularly dedicated organisations, trying to support free knowledge.

Fitting the ball’s guidelines, the award will be presented at the 6th Vienna Ball of Sciences on 25 January 2020.

Find out more and nominate yourself or someone else until the 15th November 2019 here.

P.S.: Of course you can find us on Wikipedia as well :

Ursula Hemetek at the Vienna Ball of Sciences 2019

At midnight ball guests were rewarded with a special treat: For the first time, the Hungarian Roma band Kalyi Jag performed at a ball and presented their music and dance highlights of 40 years on stage. Their show was announced by Ursula Hemetek,  Wittgenstein prize awardee 2018 and ethnomusicologist at the University of Music and applied Arts Vienna. In her research, she called their music “ethnic mainstream”. But see for yourself:

Infrared Revelations

Our ball embassador, astronomer  Franz Kerschbaum, came up with something great for the ball night: He wanted to look for the hottest dancers in the ball disco using his infrared camera. Whoever was too busy dancing, can now try retrospectively to figure out his or her temperature!

Anna Wexberg-Kubesch

Three years ago, Anna Wexberg-Kubesch started a project: The design of 15,000 postcards, representing 15,000 Jewish children murdered in Theresienstadt or after deportation to extermination camps. People across the world were invited to individually design a card and return it to Wexberg-Kubesch. The complete collection can be viewed in an installation at the Volkshalle of the Rathaus until January 30th, or as a virtual photo album at

In the ball magazine she talked about her experience. You can read the article in German here:

Dance Preparations at the Wiener Eistraum

Your legs are still tired and not ready for dancing? We recommend a practice run at the ice skating rink “Wiener Eistraum” by our ball partner Vienna Marketing. On 9000 square meters you will find enough space for a waltz on the ice. Let alone 850 squaremeters on a terrace and 550 meters which lead you through the Rathauspark straight – and hopefully on time – to the ball entrance in Lichtenfelsgasse!

19th of January until 3rd of March 2019, 10:00 – 22:00.
