THE FUNDAMENTAL RECTIFICATION OF DARWIN’S THEORY WAS PROVIDED IN 1889 BY HUGO DE VRIES IN HIS BOOK INTRACELLULARE PANGENESIS AND HAD GREAT INFLUENCE ON THE GRADUAL DEVELOPMENT OF THEORETICAL INSIGHT INTO GENETICS, EVOLUTION, AND THE SPECIES CONCEPT
HUGO de VRIES (1848-1935) SIGNED QUOTE BY GOETHE, “Hugo deVries”, 10 Feb 1909, Amsterdam, on a card 4 x 2.25, by the Dutch botanist and one of the first geneticist who is known for suggesting the concept of genes, rediscovering the laws of heredity in the 1890’s while apparently unaware of Gregor Mendel’s work, for introducing the term “mutation”, and for developing a mutation theory of evolution. He was a full professor of plant physiology at the University of Amsterdam and also a professor and director of Amsterdam’s Botanical Institute and Garden (1885-1918). He specifically postulated that inheritance of specific traits in organisms comes in genes. In his own time De Vries was best known for his mutation theory and his book The Mutation Theory. He also wrote Species and Varieties: Their Origin by Mutation (1905) and Plant Breeding (1907). His hand written Quote from the first two lines of a poem by Goethe called Epirrhema (c.1819) in full translation: “You must, when contemplating nature/Attend to this, in each and every feature.” In fine condition, with minor age toning.
