Gregor Johann Mendel (July 20, 1822 – January 6, 1884) was a Moravian Augustinian priest and scientist often called the "father of modern genetics" for his study of the inheritance of traits in pea plants. Mendel showed that the inheritance of traits follows particular laws, which were later named after him. The significance of Mendel's work was not recognised until the turn of the 20th century. Its rediscovery prompted the foundation of genetics.
