Erich von Tschermak-Seysenegg (Vienna, 1871 – 1962), an agronomist at the Vienna University of Agriculture, publishes in June 1900 "Über künstliche Kreuzung bei Pisum sativum" in the Berichte der Deutschen Botanischen Gesellschaft, being the third of the simultaneous rediscoverers of Mendel's laws. Tschermak was the grandson of the botanist Eduard Fenzl, who had been Mendel's teacher in Vienna — a generational link underscoring the continuity of the Viennese botanical tradition. His contribution was applying the results to crop improvement, anticipating applied genetics and modern agriculture.
