Noël Bernard (botanist)


Noël Pierre Joseph León Bernard was a French botanist, known as the famous discoverer of the symbiotic germination of orchid seeds. He also discovered Phytoalexins which are antimicrobial and often antioxidative substances synthesized de novo by plants that accumulate rapidly at areas of pathogen infection.

Early life and education

His father was François Bernard, a wealthy cloth and textiles distributor based in Béziers in southern France, who moved to Paris and died when Bernard was 5 years old. His mother was Marie-Marguerite, who worked as a milliner to fund his studies. Bernard was considered an outstanding student while attending the Lycée Charlemagne later Lycée Condorcet senior high schools, both located in Paris, in preparation for entry to the Grandes Ecoles, of which he eventually gained entry to the grand school École Normale Supérieure. Bernard eventually gained a Bachelor of Science with Honours between 1895 and 1897 in Mathematics, Physics, Biology and Geology. Around the same time, he started giving lessons to repay his mothers debts, sometimes to royal families, e.g. Martha, Princess Bibesco, which was ironic as he considered himself an anarchist. In 1898, he prepared for the prestigious Agrégation Des Sciences Naturelles examination for selection of high school teachers. He shared first place with Charles Pérez, the future Professor of Zoology.

Career

In 1898, Noël Bernard, started a thesis on orchids at the Botany department of the Ecole Normale Supèrieure under Professor J. Constantin with a thesis entitled: Studies on tuberization in 1901. He also took a courses in microbiology at the Pasteur Institute, taught by Émile Duclaux, Roux and Élie Metchnikoff.
At the age of 25, while out a walk in the Fontainebleau forest close to Melun he discovered a dead, broken inflorescence of the achlorophyllous orchid Neottia nidus-avis that suggested to him a theory for orchid seed germination. He presented his ideas regarding the orchid seed germination to the French Academy of Sciences in the same year.
Bernard had made an enemy at the Ecole Normale Supérieure in Gaston Bonnier, who failed to support Bernard for a full professorship. Bonnier called Bernard the l’homme aux tubercules, the tuber guy, and pushed him to move to Caen. In 1899, Bernard was offered an assistant professorship at Caen Botanical Institute headed by Octave Lignier. After Bernard’s death, Bonnier told Bernard’s family that he regretted not having enrolled Bernard in his own laboratory.
In 1908 he was appointed a professor at the University of Poitiers to teach botany. He worked primarily on the mycorrhizae in the role of orchid seed germination. He demonstrated at the Botanical Institute of the Garden of plants of Caen the symbiosis of the fungi in the tuberated roots of orchids. He participated in the creation of the plant research station of Mauroc in Saint-Benoît. With the mathematician Émile Borel, biologist Maurice Caullery and the physicist Aimé Cotton, he co-published the scientific and literary journal La Revue du mois.

Personal life

In 1907, he married Marie-Louise Martin, a mathematician from the :fr:École normale supérieure de Fontenay-aux-Roses|Ecole Normale Supérieure de Fontenay-aux-Roses.They had a son, Francis. Bernard died when he was finally overcome with tuberculosis.
