Hugo de Vries

Born in Haarlem in 1848, Hugo de Vries became one of the leading plant scientists of his time. He studied botany and went on to build his career in the Netherlands, earning a reputation for careful experiments and bold ideas about how traits are passed from one generation to the next.

De Vries is best known as one of the early figures in genetics. In the late 1890s, he was among the scientists who brought renewed attention to Gregor Mendel's work on heredity, and he played a major role in shaping how later researchers thought about genes and inherited traits. He also popularized the biological use of the word "mutation" and developed a theory of evolution that emphasized sudden changes in plants.

His work helped connect older natural history with the emerging science of modern genetics. Although some of his ideas were later revised, his influence remained strong, and he is still remembered as an important bridge between Darwin's era and twentieth-century biology.
