Jean-Baptiste Boussingault, French Chemist
Jean-Baptiste Joseph Dieudonn̩ Boussingault (1802-1887) was a French chemist who made significant contributions to agricultural science, petroleum science and metallurgy. He devoted himself mainly to agricultural chemistry and animal and vegetable physiology, with occasional excursions into mineral chemistry. His work included papers on the quantity of nitrogen in different foods, the amount of gluten in different wheats, investigations on the question whether plants can assimilate free nitrogen from the atmosphere (which he answered in the negative and propose the basis of what became known as the nitrogen cycle), the respiration of plants, the function of their leaves, the action and value of manures and chemical fertilizers. Boussingault was an outstanding personage in agricultural science, conducting the world-s first agricultural experimental station and making a series of discoveries that were to become the foundation of the modern agriculture that feeds us all. He lived to be 85 and died of natural causes.
