Gregor Mendel (1822 - 1884)

Gregor Johann Mendel (July 20, 1822 – January 6, 1884) was a German-speaking Silesian scientist and Augustinian friar who gained posthumous fame as the founder of the new science of genetics. Mendel demonstrated that the inheritance of certain traits in pea plants follows particular patterns, now referred to as the laws of Mendelian inheritance. The profound significance of Mendel's work was not recognized until the turn of the 20th century, when the independent rediscovery of these laws initiated the modern science of genetics.
