Gregor Mendel

Gregor Mendel (1822–1884) was an Augustinian friar and naturalist at the monastery of St. Thomas in Brno whose experiments crossing some 28,000 pea plants, reported in his 1866 paper Versuche über Pflanzen-Hybriden ("Experiments on Plant Hybrids"), established the basic laws of inheritance and are now read as the founding work of genetics — though they were largely ignored until their "rediscovery" around 1900.

In this vault Mendel is not primarily the father of genetics but the subject of its founding integrity puzzle: the segregation ratios he reported fit the theoretically predicted values (such as 3:1) so closely that R. A. Fisher, re-analyzing them in 1936, judged the fit too good to be ordinary sampling luck. That verdict — genuinely contested to this day, with candidate explanations running from an over-eager assistant to unconscious classification bias — is the earliest anchor of the vault's "suspicious perfection" cluster.
