Live and act
Balard first completed an apprenticeship as a pharmacist in his native Montpellier. Inspired by the discovery of iodine by Bernard Courtois in 1811 in brown algae in the North Sea, he tried to follow him. When investigating brown algae of a Fucus sec. In the salty waters of the Languedoc , he discovered in 1826 that the residues contained, in addition to chloride and iodide , another, hitherto unknown halogen. As a result, he succeeded in isolating it. Because of the foul smell, he named this chlorine-like substance bromine or bromine and determined the properties of this newly discovered element.
He discovered the sensitivity of silver bromide to light . He later proved the presence of bromine in sea plants and marine animals. The discovery of bromine was actually a by-product of his research on the sea and its life forms. Balard also carried out research into inexpensive methods of desalination of seawater. Louis Pasteur and Marcellin Berthelot were two of his students.
In 1844 he was elected to the Académie des Sciences .
