Symposium honours the founding president of the German Society for Plant Sciences
To celebrate the 200th birthday of the phycologist Nathanael Pringsheim (30 November 1823 – 6 October 1894), the Matthias-Schleiden-Institute at the University of Jena, where Pringsheim was a professor for around four years, held a symposium on 19 December. In her introductory remarks, phycologist Professor Dr Maria Mittag placed Pringsheim in the ranks of the Institute's outstanding professors. DBG's president, Professor Dr Andreas Weber, reported on the history of our German Society for Plant Sciences (DBG), which Pringsheim founded in Berlin in 1882, under the title "From 1882 to 2023: 141 years of promoting plant science". Pringsheim led our society until his death in 1894. He was instrumental in the transition from an association into a scientific society [1]. Professor Dr Andreas Deutsch introduced the sexual revolution in algal research in citing important scientific findings that Pringsheim elicited from algae: "Nathanael Pringsheim was able to observe how male gametes swam towards female egg cells and united with them in an inconspicuous alga. This discovery, made in 1855, was a scientific sensation," Deutsch writes in his latest book [2]. This was the first direct observation of the fertilisation process in a living organism.
