Hugo De Vries
Hugo Marie de Vries (; 16 February 1848 – 21 May 1935) 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 evolution. Early life De Vries was born in 1848, the eldest son of Gerrit de Vries (1818–1900), a lawyer and deacon in the Mennonite congregation in Haarlem and later Prime Minister of the Netherlands from 1872 until 1874, and Maria Everardina Reuvens (1823–1914), daughter of a professor in archaeology at Leiden University.

Costera (plant)
''Costera'' is a genus in the Ericaceae found in the Malesian floristic region. It is a small genus of often epiphytic shrubs that grows in tropical rainforests. Description ''Costera'' is a small genus of shrubs with glabrous, leathery, unlobed leaves arranged in alternate phyllotaxy. The inflorescences are axile and sessile; flowers emerge in bundles directly from the stem. The flowers are small and tetramerous or pentamerous. They are directly attached to the stem via a pedicel with 2 basal bracts. The calyx is mostly fused and forms 4 or 5 apical teeth, which are the unfused tips of the sepals. The 4 or 5 petals are also fused into a short tube, and the inner surface of the corolla contains minute laciniate projections toward the base. The alternating stamens are lightly appressed to the corolla and have a short linear filament. The anthers are elongated, tubular, and erect. They face inward and release pollen through an apical pore. The ovary is inferior and is divided i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Charles Darwin
Charles Robert Darwin ( ; 12 February 1809 – 19 April 1882) was an English Natural history#Before 1900, naturalist, geologist, and biologist, widely known for his contributions to evolutionary biology. His proposition that all species of life have descended from a Common descent, common ancestor is now generally accepted and considered a fundamental scientific concept. In a joint presentation with Alfred Russel Wallace, he introduced his scientific theory that this Phylogenetics, branching pattern of evolution resulted from a process he called natural selection, in which the struggle for existence has a similar effect to the artificial selection involved in selective breeding.. Darwin has been described as one of the most influential figures in human history and was honoured by Burials and memorials in Westminster Abbey, burial in Westminster Abbey. Darwin's early interest in nature led him to neglect his medical education at the University of Edinburgh Medical Schoo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hogere Burgerschool
The ''Hogere Burgerschool'' (''HBS'') (Dutch: Higher Civic School) was a secondary school type that existed between 1863 and 1974 in the Netherlands and the Dutch Empire. These schools, with a five- or sometimes six-year program, continued in 1968 as VWO. The last HBS diplomas were given out in 1974. History The HBS is a mid-19th-century creation by the liberal politician Johan Rudolph Thorbecke, and resulted from the law on secondary education enacted in May 1863. Along with the creation of ''burgerscholen'' in each city of more than 10,000 inhabitants, the HBS was intended as a practically oriented education for higher functions in industry and trade. It was explicitly not intended as a sufficient education to enter university. According to historian Hans Verhage the form "''hogere-burgerschool''" (the hyphen indicating that ''hogere'', "higher", modifies ''burger'', "citizen") is linguistically correct, since it was a schooling system geared toward higher-ranked citizens, a ...

Johannes Jacobus Smith
Johannes Jacobus Smith (Antwerp 29 June 1867 – Oegstgeest 14 January 1947) (sometimes written as Joannes Jacobus Smith) was a Dutch botanist who, between years 1905 to 1924, crossed the islands of the Dutch East Indies (mainly Java), collecting specimens of plants and describing and cataloguing the flora of these islands. The standard botanical author abbreviation J.J.Sm. is applied to plants described by J.J. Smith. The description of the flowers of the western half of New Guinea (then a Dutch territory) is largely based on his work. He was, next to Rudolf Schlechter, the most prolific author on New Guinea orchids. He also described numerous plants from other families, such as Ericaceae and Euphorbiaceae. Biography Smith was born in Antwerp where his father worked in the postal department. The family moved to Utrecht in 1872 and to Amsterdam in 1875. He took an interest in growing plants and keeping animals. One of his secondary school teachers was Jan Costerus who advised hi ...
