He bred pea plants in a monastery garden and worked out the rules of inheritance - dominant, recessive, the math behind why children resemble parents - then published it in 1866 to total silence. Thirty-four years after that, three scientists read his paper the same year and realized he'd already solved genetics.

About this person

Gregor Johann Mendel was born into a German-speaking family in the Austrian Empire on 20 July 1822, became an Augustinian friar, and eventually abbot of St. Thomas' Abbey in Brno. Between 1856 and 1863 he crossbred pea plants, tracking seven traits - height, pod shape and color, seed shape and color, flower position and color - and noticed patterns: yellow seeds dominated in one generation, then green reappeared at a ratio of 1 to 3. He coined "recessive" and "dominant" to explain it, published his findings on invisible "factors" in 1866, and was ignored. In 1900, sixteen years after his death, Erich von Tschermak, Hugo de Vries, and Carl Correns each verified his results independently, and the modern science of genetics began. The actual genes he'd inferred were finally identified in 2025.
