Bernard de Jussieu (August 17th 1699 with Lyon, France - November 6th 1777 with Paris) is a Botaniste French.
Bernard, brother of Antoine and Joseph de Jussieu, begins his studies with the college Jesuit of Lyon, then continues them in Paris. They are stopped by the invitation of his/her Antoine brother to come to herborize at his sides at the time of voyages naturalists in Spain and with the Portugal.
On its return, in 1720, it passes the rank of doctor of medicine to Montpellier. But its passion for botany leads it to give up the exercise of medicine. It returns to Paris and, in 1722, takes the post of professor of botany to the Jardin of the king whom vacant the death of Sebastien Vaillant left. It remains in this place all its life and contributes to the increase in the herbarium, often with its expenses. Under his direction, the droguier of the Garden takes a considerable dimension and adopts the name of Cabinet of the king.
With a great modesty, it is satisfied with its station to the Garden of the king and refuses even the load of botanist of the king, free after the death of his Antoine brother. Bernard de Jussieu publishes only very little works. In 1725, it makes appear an increased version of the Histoire of the plants of the surroundings of Paris of Tournefort and is allowed the same year with the Academy of Science. In 1727, he becomes member of the Royal Society.
It explores the coasts of Normandy in 1742 and publishes its Mémoires , reporting its voyage and describing the plant species, but as animal as it met there. It is the first to have separated the Baleine from the Poisson S. In 1758, Louis XV entrusts to him the creation of a school of botany in the gardens of Trianon, directed by Claude Richard. Bernard does not follow for that the classification of Linné, but develops a new system, based on the morphological characters of the plants. He subdivides initially the species in Monocotylédone S and Dicotylédone S, then in families gathered according to their morphological affinities.
It is this system which takes again and closely connected its nephew Antoine-Laurent de Jussieu.
