Faith in Action #8: Father Gregor Mendel: The Augustinian Monk Who Became the ‘Father of Genetics’

May 23, 2025

Imagine a world where the mysteries of genetic inheritance were as enigmatic as the stars. In the mid-1800s, amidst the serene gardens of St. Thomas's Abbey in Brno (a city in the modern-day Czech Republic), Gregor Mendel, an Augustinian friar with a passion for nature and mathematics, embarked on experiments that would unravel these mysteries. Tending to his pea plants, Mendel wasn't just gardening; he was pioneering the field of genetics, laying the groundwork for a science that would transform our understanding of life itself

The Formative Years of a Genius

Born Johann Mendel on July 20, 1822, in the Margraviate of Moravia—then part of the Austrian Empire —he was raised in a German-speaking family from the Silesian region, now located in the modern-day Czech Republic.

From 1840 to 1843, Mendel studied philosophy and physics at the Philosophical Institute of the University of Olomouc. Encouraged by his physics teacher, Friedrich Franz, he joined the Augustinian Abbey of St. Thomas in Brno, where he began training as a Catholic priest. Upon entering the order, he took the name "Gregor"

Mendel’s Revolutionary Pea Plant Experiments

Between 1856 and 1863, Mendel conducted meticulous experiments with over 28,000 pea plants in the garden of St. Thomas Abbey. He crossbred pea plants with different traits—flower colour, seed shape, and pod form—carefully tracking how these characteristics passed from generation to generation.

From his observations, Mendel formulated what are now known as the Laws of Inheritance—the law of segregation and the law of independent assortment. He uncovered the basic principles of dominant and recessive traits, genes, and alleles long before the word “gene” even existed. And he did it all while wearing the robes of a priest. His findings were published in 1866, but the world paid little attention until they were rediscovered decades later.

From Obscurity to the 'Father of Genetics'

Mendel passed away on 6 January 1884, at the age of 61. Unfortunately, his discoveries in the field of genetic inheritance went unrecognised during his lifetime. It wasn’t until the early 20th century that scientists rediscovered his research and realised its groundbreaking implications. Today, Mendel is revered as the “father of genetics”, and his principles are taught as fundamental truths in biology classrooms worldwide.

In 2025, scientists achieved a remarkable feat by identifying the specific genes behind the traits Mendel had studied, using genomic data from over 700 pea plant varieties. This modern validation of Mendel’s 19th-century hypotheses showcases the enduring accuracy and relevance of his work.

Conclusion

Gregor Mendel didn’t seek fame or fortune—his life's work was driven by wonder, discipline, and a devotion to truth, both spiritual and scientific. His legacy lives on not just in biology textbooks, but in the billions of lives shaped by genetic science today—from medicine to agriculture, from ancestry tests to gene therapy.

From the humble garden of a Moravian monastery to the frontiers of genetics, Mendel’s legacy continues to inspire scientists and seekers alike, reminding us that sometimes, the greatest discoveries grow quietly in the most unexpected places.
