Hugo de Vries was a Dutch botanist who was then at the height of his fame as the originator of the mutation theory and one of the founders of the science of genetics.
Hugo de Vries was born in Haarlem, in The Netherlands, on 16 February 1848, the oldest son of an old and influential family.
De Vries and Roberts must have gotten along very well for instead of staying for a day, as originally intended, he stayed for almost two weeks, 3-17 May. Consequently he had to shorten his visit to the Grand Canyon and the petrified forest from the two weeks which were originally planned to three days.

De Vries was educated at the Universities of Leiden, Heidelberg and Wruzburg.
De Vries conducted a series of experiments hybridising varieties of plants in the 1890s and he discovered new forms among a display of the (Any of several plants of the family Onagraceae) evening primrose Oenothera lamarcklana growing wild in a waste meadow.
In the late 1890s, de Vries became aware of Mendel's obscure paper of 40 years earlier, and he altered some of his terminology to match.

De Vries looked at the valley through the eyes of a botanist and agriculturist and was especially interested in the desert as it was before settlement had taken place.
De Vries planned to take the adaptation of plants to a hostile environment as his next research project, hence his interest in desert plants.
When de Vries returned to the United States in the spring of 1906, the disaster situation was at its height.

De Vries's contemporary W. Johannsen (1857-1927) added impetus to the classical mutation theory by demonstrating that variation in the size of garden beans did not respond to the effect of natural selection (1).
They reexamined de Vries's data and found that the mutants he obtained were actually an assemblage of diverse mutations that appeared to be drastically different from its parental plant.
These findings led de Vries to conclude that sudden mutation gives rise to new species that he understood to mean a new line of pure-breeding genetically identical individuals.

The essay describes the development of Hugo de Vries's thinking on heredity from the publication of his Intracellulare Pangenesis in 1889 to the publication of Die Mutationstheorie, Volume 2, in 1903.
De Vries's work in the 1890s can be characterized as an attempt to defend his theory of pangenes, especially the fundamental and controversial idea that different characters have different material hereditary carriers.
Recently discovered research notes on hybridization from 1896 suggest that, though he was unaware of Mendel's work, De Vries used the laws of dominance and recessiveness, segregation, and independent assortment to explain the 75:25 ratio in the second generation.

In 1900 Dutch botanist Hugo Marie de Vries independently derived the same conclusions about genetics that Austrian monk Gregor Mendel first proposed half a century earlier.
With the publication of his book The Mutation Theory, de Vries introduced mutation as a source of change in a single generation, further complicating the volatile evolutionary debate.

In 1889 De Vries had hypothesized the existence of "pangenes" (now called "genes") and argued for a saltationist mechanism of evolution, with selection only operating to produce local varieties.
De Vries conducted lecture tours of the U.S. in 1904 and 1906.
De Vries' views strongly influenced Bateson and many American experimental biologists like Morgan.

 Sensitive periods - Wikipedia, the free encyclopedia
Maria Montessori believed that every human being goes through a series of quantum leaps in learning during the preschool years.
Drawing on the work of the Dutch geneticist Hugo de Vries, she attributed these behaviors to the development of specific areas of the human brain, which she called nebulae (Montessori, 1949, p.
She felt this was especially true through the first few years of life, from birth (or before) to the time of essentially complete development of the brain, about age 6 or 7.

This famous marine biological expedition was led by a colleague of Hugo de Vries: the Amsterdam Professor of Zoology Max Wilhelm Carl Weber, born 1852.
In the same year Weber took out papers of naturalization (the actual record of naturalization was registered 27 December 1887; Pieters and De Visser, 1985) and married Anna Antoinette van Bosse, a wealthy widow of his own age (born 27 March 1852 in Amsterdam).
During her brief widowhood she had been a diligent pupil of Hugo de Vries and was on her way to become a skilful and learned botanist, specializing in marine Algae.
