Gregor Mendel

Gregor Mendel

Gregor Mendel (1822–1884) was an Augustinian friar and scientist in the Austrian Empire whose experiments on pea plants laid the foundations of genetics. Born to a farming family in Silesia, he entered the Abbey of St. Thomas in Brno in 1843, where the community supported his studies in natural science at the University of Vienna. Between 1856 and 1863 he cultivated and tested many thousands of pea plants in the abbey garden, tracking traits such as seed shape, flower color and plant height across generations. He found that traits are passed on in predictable ratios through discrete hereditary factors, now called genes, and described the principles of segregation and independent assortment, together with dominant and recessive traits. Published in 1866, his findings received little notice in his lifetime; he became abbot in 1868. Rediscovered in 1900, his work is now recognized as the beginning of modern genetics.

Scientists of Christian Faith

For these scientists, studying nature and keeping faith went hand in hand. Kepler wrote that through his astronomy God was being celebrated. Pascal, a mathematician and physicist, wrote the reflections later published as the Pensées in defense of Christian faith. Faraday served as an elder of his small Christian congregation in London. Mendel carried out his experiments on pea plants as an Augustinian friar and later became abbot of his monastery in Brno. Maxwell held a lifelong Christian faith alongside his physics.
