The Leopoldina is located in Halle. Founded in 1652, the Leopoldina claims to be the oldest continuously existing learned society in the world.
The Leopoldina is the first and foremost academic society in Germany to advise the German government on a variety of scientific matters, for instance on climate change.
The Leopoldina gives conferences and lectures and continues to publish the Ephemeriden under the name Nova Acta Leopoldina. It issues various medals and awards, offers grants and scholarships and elects new members to itself. The Academy also maintains a library and an archive and it also researches its own history and publishes another journal, Acta Historica Leopoldina devoted to this subject.
Three quarters of the members are from German-speaking countries (Germany, Austria, Switzerland) and one quarter from about 30 other nations. The election to membership of the Leopoldina is the highest academic honour awarded by an institution in Germany.
As of early 2014, a total of 169 Nobel prize laureates are fellows of the Leopoldina.
