Gregor Mendel
Gregor Mendel was an Austrian friar and scientist whose experiments with pea plants established the fundamental laws of heredity, earning him recognition as the founder of modern genetics.
Working in the garden of his monastery, Mendel spent years crossbreeding pea plants and carefully tracking traits like seed color and plant height across generations, identifying consistent patterns in how traits were inherited.
His 1866 paper outlining what became known as Mendelian inheritance, including the concepts of dominant and recessive traits, received little attention during his lifetime and was largely overlooked until being rediscovered around 1900.
Once recognized, Mendel's principles became the foundation of the modern field of genetics, and his pea plant experiments are still taught today as a foundational example of the scientific method.
