The book "250 Years / 250 Lat Societas Jablonoviana" by Ewa Tomicka-Krumrey and Willi Hameister offers a comprehensive examination of the Societas Jablonoviana, which was founded in 1774 by Józef Aleksander Jabonowski. This unique foundation has fulfilled its mission for over two and a half centuries and serves as a significant example of bilateral cooperation between Poland and Germany. On the occasion of its 250th anniversary, the history of this society is honored, which has not only influenced the scientific landscape in the German-speaking world but has also promoted the German-Polish dialogue. The book is the result of an exhibition aimed at making knowledge about the Societas Jablonoviana accessible to a broader audience. It includes historical reconstructions, biographical insights, and contextual information that underscore the relevance of the foundation in today's context.
