Balard, Antoine

Antoine Jerome Balard (1802-1876) treated a caustic solution obtained from the ashes of seaweed with chlorine water. Besides iodine, bromine was formed. 

Bromine - the atomic number is 35 and the chemical symbol is Br. The name derives from the Greek bromos for stench or bad odor . It was first prepared by the German chemist Carl Ldwig in 1825 but it was first publically announced in 1826 by Balard and so the discovery is therefore credited to the French chemist and pharmacist Antoine-Jerome Balard.

Antoine-Jerome Balard, 1802-1876. French chemist and pharmacist who discovered bromine. Professor of chemistry at the Sorbonne and at the College de France. He discovered hypochlorous acid, worked out the con-situation of Javelle water, and perfected industrial methods for extracting various salts from sea water. 

Antoine-Jerome Balard (14), was born at Montpellier on September 30, 1802. Since his parents were poor, he was adopted and educated by his godmother. He studied at tire College of Montpellier for a time, and at the age of seventeen years he became a preparateur at the Ecole de Pharmacie, where he graduated in 1826 (47, 66, 68).

Bromine was discovered, at almost the same time in 1826, by two men, German chemist Carl Lowig (1803—1890) and French chemist Antoine-Jerome Balard (1802—1876). Although Balard announced his discovery first, Lowig had simply not completed his smdies of the element when Balard made his announcement. 

French chemist Antoine-Jerome Balard and German chemist Leopold Gmelin independently discover bromine. 

Bromine is a member of a family of elements known as halogens that are found in group 7A of the Periodic Table. Bromine was discovered in 1826 in Montpelher, France, by French chemist Antoine J. Balard. 

Le Bel was born into a wealthy family that controlled the petroleum industry in Pechelbronn, Alsace. In 1865 he was sent to the Ecole Polytechnique in Paris to obtain a chemical education and spent most of his time there doing chemical research. After graduation, he worked with the French chemists Antoine Balard and Adolphe Wurtz in Paris, in between intermediate periods of refinery construction at home. Finally in 1889, he sold his shares in the family business and established a private laboratory in Paris where he devoted himself to organic chemistry and, in his later years, paleontology, botany, and philosophy. An independent thinker who never held an academic appointment, Le Bel did manage to achieve general recognition as a chemist and even became president of the French Chemical Society in 1892. 

All these industrial innovations would have their own impact on other developments in industrial and then medicinal chemistry. At the beginning of the nineteenth century, as the result of a scientific approach, drugs were becoming an industrial item. Claude Louis Berthollet (1748-1822) begins the industrial exploitation of chlorine (circa 1785). Nicolas Leblanc (1742-1806) prepared sodium hydroxide (circa 1789) and then bleach (circa 1796). Davy performed electrolysis and distinguished between acids and anhydrides. Louis Jacques Thenard (1777-1857) prepared hydrogen peroxide and Antoine Jerome Balard (1802-1876) discovered bromide (1826).

Let s go back for a moment to 1826. The place is Montpellier, France, home of pharmacy student Antoine-Jerome Balard. Professor Joseph Anglada asks him to look into the possibility of isolating useful substances from the residue that s left when seawater evaporates. Balard treats the residue with chlorine, and this yields a dark brown liquid with an intense smell. Its chemical properties are similar to those of chlorine and iodine, but Balard recognizes it as a new element. He calls it bromine, after the Greek word bromos, which means stink. ... 

The first to catch a glimmering of order was the German chemist Johann Wolfgang Dobereiner (1780-1849). In 1829, he noted that the element bromine, discovered three years earlier by the French chemist Antoine Jerome Balard (1802-76), seemed just halfway in its properties between chlorine and iodine. (Iodine had been discovered by... 

Bromine was discovered by a German student named Carl Lowig. Lowig produced a sample for his professor that he collected from a spring in his home town. A year later, Antoine-Jerome Balard isolated bromine from seawater and presented it to the French Academy in 1826.
