Who they are
Gregor Mendel (1822–1884) was a friar at a monastery in Brno, Austria, who over about eight years in the monastery garden systematically grew and cultivated tens of thousands of pea plants, and, by carefully recording the inheritance-distribution patterns of clearly distinguishable traits of the pea plants — seed shape, flower color, plant height — across successive generations, distilled the law of segregation and the law of independent assortment thereafter called the "Mendelian laws of inheritance," for the first time revealing that the inheritance of biological traits is not the "blood-blending" continuous gradual process previously widely believed but is determined by pairs of mutually independent, discretely transmitted hereditary factors (later called "genes") passing by specific statistical laws. When Mendel published this research in 1866 it drew almost no attention or response in the science of the time, and this research, thereafter acknowledged as the foundational breakthrough of genetics, was rediscovered and its historical value acknowledged only in 1900, sixteen years after his death, by three scientists who had independently done similar research; Mendel is thereby often called a typical case in the history of science of "obscure in life, revered after death." The laws of heredity he revealed thereafter became the theoretical cornerstone on which all modern genetics, breeding science, and even genetic engineering and biotechnology could be built.

Key stories
Eight Years, Tens of Thousands of Pea Plants
Mendel chose peas as his experimental subject because peas had the unique advantages of several pairs of clearly distinguishable traits — round or wrinkled seed, purple or white flower — and could have their pollination strictly controlled, and he spent about eight years systematically growing tens of thousands of pea plants, carefully recording the distribution ratios of each trait in the offspring generation by generation, and at last distilling from these seemingly dull, tedious statistics the two great laws revealing the basic law of biological heredity.
A Discovery Obscure in Life, Acknowledged Only After Death
Mendel published this research, thereafter acknowledged as of epoch-making significance, in a local scholarly journal in 1866, but in his lifetime the paper drew almost no response or discussion in the mainstream science of the time, and Mendel thereafter gradually withdrew from research to focus on the monastery’s daily affairs, dying in 1884 without seeing his discovery gain the recognition it deserved; only in 1900, sixteen years later, did three scientists who had independently done similar genetics research almost simultaneously rediscover Mendel’s original paper and publicly acknowledge him as the true earliest discoverer of this law of heredity.
Version differences
Whether Mendel’s original experimental data were "too perfect," with statistically unnatural regularity, was questioned by a statistician in the twentieth century, but mainstream scholarship still acknowledges the scientific correctness of the laws of heredity he revealed.
