Hugo Marie de Vries (Dutch pronunciation: [ˈɦyɣoː də ˈvris]; 16 February 1848 – 21 May 1935) [2] was a Dutch botanist and one of the first geneticists.He is known chiefly for suggesting the concept of genes, rediscovering the laws of heredity in the 1890s while apparently unaware of Gregor Mendel's work, for introducing the term "mutation", and for developing a mutation theory of ...
Erich von Tschermak. Erich Tschermak, Edler von Seysenegg (15 November 1871 – 11 October 1962) was an Austrian agronomist who developed several new disease-resistant crops, including wheat-rye and oat hybrids. He was a son of the Moravia-born mineralogist Gustav Tschermak von Seysenegg. His maternal grandfather was the botanist, Eduard Fenzl ...
Painting of Hugo de Vries, making a painting of an evening primrose, which had apparently produced new forms by large mutations in his experiments, by Thérèse Schwartze, 1918. The pattern of repeated colonizations resulted in a unique genetic conformation in the Euoenothera whereby the chromosomes at meiosis can form circles rather than pairs.
De Vries is one of the most common Dutch surnames. [1] It indicates a geographical origin: "Vriesland" is an old spelling of the Dutch province of Friesland (Frisia). Hence, "de Vries" means "the Frisian". The name has been modified to "DeVries", "deVries", or "Devries" in other countries. People named De Vries:
William Bateson. William Bateson (8 August 1861 – 8 February 1926) was an English biologist who was the first person to use the term genetics to describe the study of heredity, and the chief populariser of the ideas of Gregor Mendel following their rediscovery in 1900 by Hugo de Vries and Carl Correns.
In 1901 the geneticist Hugo de Vries gave the name "mutation" to seemingly new forms that suddenly arose in his experiments on the evening primrose Oenothera lamarckiana. In the first decade of the 20th century, mutationism, or as de Vries named it mutationstheorie , became a rival to Darwinism supported for a while by geneticists including ...
Carl Erich Correns (19 September 1864 [2] – 14 February 1933) was a German botanist and geneticist notable primarily for his independent discovery of the principles of heredity, which he achieved simultaneously but independently of the botanist Hugo de Vries, and for his acknowledgment of Gregor Mendel's earlier paper on that subject.
