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.
