Discovery of the Mendelian ratios, the most significant single achievement in the history of genetics. The story of how Mendel published his paper in this relatively obscure journal only to have his discovery ignored during his lifetime has been frequently retold. In 1900 Correns and de Vries (Nos. 239.01 and 239.1) rediscovered the Mendelian ratios almost simultaneously. William Bateson first translated the above work into English in J. Roy. Hort. Soc., 1901, 26, 1-32. The following year he published his first monograph on Mendel (No. 241).
