Johann Mendel is another way of referring to Gregor Mendel, the Austrian monk and scientist who discovered the basic principles of heredity. 'Johann' was his given name at birth, and he later became known as 'Gregor' upon entering monastic life. He's most famous for his experiments with pea plants, which led to the understanding of how traits are passed down. Think of it like a superhero having a secret identity.
