Hugo de Vries, Dutch botanist
Hugo de Vries (1848-1935). Caricature of the Dutch botanist and geneticist Hugo Marie de Vries. De Vries is best known for his breeding experiments with evening primrose plants, which led him to a general theory of mutations, an alternative to Darwinian theory. This was later shown to be wrong, due to the complex genetics of the evening primrose, but did much to stimulate experiment and debate in genetics. He also worked on plant turgor (stiffening of the cell walls due to osmotic water uptake), using the term plasmolysis to describe loss of turgidity.
