Albert Jean Baptiste Marie Vayssière (8 July 1854, Avignon – 13 January 1942, Marseille) was a French scientist, a biologist, specifically a malacologist and entomologist, i.e. someone who studies mollusks, and insects. Within the Mollusca, Vayssière specialized in sea slugs and bubble snails, i.e. marine opisthobranch gastropods. He made significant contributions towards a better understanding of the general biology, phylogenetic relationships, biogeography and ecological distribution of the group.From 1873 to 1883, Vayssière served as a préparateur to the Faculté des Sciences at Marseille, where afterwards he was maître de conférences (lecturer). He later served as a professor of zoology, and in 1915 he was appointed director of the Muséum d'histoire naturelle de Marseille.Vayssière was also interested in entomology, in particular, the field of agricultural entomology.
Félix-Archimède Pouchet (26 August 1800 – 6 December 1872) was a French naturalist and a leading proponent of spontaneous generation of life from non-living materials, and as such an opponent of Louis Pasteur's germ theory. He was the father of Georges Pouchet (1833–1894), a professor of comparative anatomy.
From 1828 he was director of the Rouen Jardin des Plantes. Later, in 1838, he became professor at the School of Medicine at the University of Rouen. His major scientific work Hétérogénie was published in 1859. He also wrote a layperson's encyclopedia The Universe, published in 1870, which gives an overview of the sciences, but in which Pouchet ridicules Louis Pasteur's theories (calling them panspermism) and atomic theory.
In 1847, Pouchet effectively launched the study of the physiology of cytology. In 1848, he was elected as a member to the American Philosophical Society.
Charles Victor Naudin (14 August 1815 in Autun – 19 March 1899 in Antibes) was a French naturalist and botanist.
Ernest Charles Philippe Auguste Munier-Chalmas (7 April 1843 – 9 August 1903) was a French geologist, born at Tournus in Burgundy, who is known for his contributions to the understanding of the Cretaceous, but who also isolated and defined the Priabonian stage of the Late Eocene, in a paper co-written with Albert de Lapparent in 1893.
From 1864 he worked as an assistant in the geology department at the Sorbonne, and subsequently participated in geological missions to Austria-Hungary and the Venetian Alps. From 1882 he taught classes at the École Normale Supérieure, and in 1891 became a professor of geology at the Sorbonne. In addition, from 1892 to 1903, he was director of studies at the École pratique des hautes études.In 1873 he described the bivalve genera Matheronia and Toucasia (family Requieniidae). With paleontologist Charles Schlumberger, he conducted important investigations on sexual dimorphism in Foraminifera.In 1891 he was appointed president of the Société géologique de France. He was elected to the mineralogical section of the French Académie des sciences on 5 May 1903.In 1895, botanist Hermann zu Solms-Laubach published Chalmasia, which is a genus of green algae in the family Polyphysaceae and name in Chalmas's honour.He died in retirement at Aix-les-Bains, Provence.
Charles François Antoine Morren (3 March 1807 in Ghent – 17 December 1858 in Liège), was a Belgian botanist and horticulturist, and Director of the Jardin botanique de l’Université de Liège.Morren taught physics at Ghent University between 1831 and 1835. At the same time he studied medicine and graduated in 1835. He became Professor extraordinarius of botany at the University of Liège from 1835 to 1837, and full professor from 1837 to 1854.
Pollination of Vanilla orchids is required to make the plants produce the pods from which vanilla extract is obtained. In 1837, Morren was among the first to publish a method for artificial pollination of Vanilla, but his method proved financially unworkable and was not deployed commercially. In 1841, Edmond Albius, a 12-year-old slave who lived on the French island of Réunion in the Indian Ocean, discovered that the plant could be hand-pollinated. Hand-pollination allowed global cultivation of the plant. Noted French botanist and plant collector Jean Michel Claude Richard falsely claimed to have discovered the technique three or four years earlier, but by the end of the 20th century, Albius was considered the true discoverer.
He was the father of Charles Jacques Édouard Morren. Morren and his son produced the journal La Belgique Horticole (35 volumes, 1851–1885).
Morren also coined the term phenology, which refers to the scientific discipline that studies the seasonal cycles of animals and plants. Morren first used the term phenology in 1849 during a public lecture at the Academy of Brussels. The first use of the term phenology in a scientific paper dates back to 1853 when Morren published “Souvenirs phénologiques de l’hiver 1852-1853” (“Phenological memories of the winter 1852-1853”). This paper describes an exceptionally warm winter when plants exhibited unusually phenological patterns.
