Gregor Mendel

Born in 1822 in what is now the Czech Republic, Gregor Mendel joined the Augustinian monastery in Brno and spent much of his life balancing religious duties with teaching and scientific study. He was especially interested in mathematics and natural science, interests that shaped the careful way he approached his experiments.

In the 1850s and 1860s, he carried out famous breeding experiments with pea plants, tracking how visible traits appeared and disappeared across generations. From this work, he identified basic patterns of inheritance that later became known as Mendel's laws, making him a foundational figure in genetics.

Mendel published his results in the 1860s, but they drew little attention at the time. Decades later, scientists recognized how important his findings were, and today he is widely remembered as the father of modern genetics.
