May 16, 1900. Hugo de Vries and Carl Correns independently recreate Gregor Mendel's work on heredity in the 1890s, publishing their findings in 1900 in the Comtes Rendus de l'Académie des Sciences. de Vries and Correns' work leads to the rediscovery of Mendel's writings, which had remained obscure since its original publication in 1865. Both sets of work become instrumental to establishing theories of genetic linkage and evolutionary biology.
