  Antoine Jerome Balard
Antoine Jerome Balard (September 30, 1802 - April 30, 1876), French chemist, was born at Montpellier.
He started as an apothecary[?], but taking up teaching he acted as chemical assistant at the faculty of sciences of his native town, and then became professor of chemistry at the royal college and school of pharmacy and at the faculty of sciences.
While the discovery of bromine and the preparation of many of its compounds was his most conspicuous piece of work, Balard was an industrious chemist on both the pure and applied sides.

 Properties other than Color
Probably this distinction was a major contribution to Antoine Lavoisier's belief that each gas is a separate element.
When Balard added chlorine water and starch to Fucus ash, two layers formed, the lower blue due to Iodine and starch, and the upper intensely yellow.
Balard succeeded Thenard at the Sorbonne where he made other discoveries and perfected industrial methods.

 It's Elemental - The Element Bromine
When he showed his professor, Leopold Gmelin, the red, smelly liquid he had produced, Gmelin realized that this was an unknown substance and encouraged Löwig to produce more of it so they could study it in detail.
Unfortunately, winter exams and the holidays delayed Löwig's work long enough for another chemist, Antoine-Jérôme Balard, to publish a paper in 1826 describing the new element.
Balard was credited with the discovery and named it after the greek word for stench, bromos.

Antoine-Jérôme Balard (1802-1876), who was working in a pharmacy school in Montpellier, studying the brown seaweed Fucus, at that time Iodine was manufactured from ash of calcinated Fucus.
Balard suggested the name muride, from the Latin word "muria" for brine.
In the mean time, in 1826, Balard published his paper describing the new element.

 Bromine | World of Chemistry
The cost of extracting the dye from the mollusks was so great that only very rich people could afford it, thus accounting for its alternative name.
Bromine was discovered at almost the same time in 1826 by the German chemist Carl Löwig (1803-1890) and the French chemist Antoine-Jérôme Balard (1802-1876).
However, Balard was the first to publish the results of his research.

 Halogens - Fluorine, Chlorine, Bromine, Iodine
Another is neoprene, a synthetic form of rubber that is resistant to the effects of heat, oxidation, and oils.
Balard chose the name bromine from the Greek word for "stink," because of its strong and disagreeable odor.
Chlorine gas is used to convert bromide compounds in brine to elemental bromine.

 CienciaNet : Bromo : Br
El químico alemán Liebig solía contar que unos años antes de que Balard descubriese el bromo, un salinero alemán le envió un frasco que contenía un líquido de color pardo para que lo examinara.
Cuando Balard anunció su descubrimiento, Liebig se dio cuenta de su error y guardo el frasco en un armario que el llamaba "l'armoire des fautes".
Este hecho lo utilizaba en sus clases para enseñar que hay que estar muy atento a los prejuicios cuando se analizan los hechos.

 Bromine (Br)   (Site not responding. Last check: 2007-10-09)
Bromine, one of the halogens, is at room temperature an extremely volatile liquid that gives off a poisonous, suffocating, reddish vapor composed of diatomic molecules.
Because bromine is so similar to the chemical properties of chlorine, it was not recognized as a separate element until 1826, when it was discovered and isolated by Antoine Jerome Balard (a French chemist).
Bromine is not found in nature as a free element, but it is found in bromide compounds.

 Bromine: Chemical Elements
Fluorine, chlorine, bromine, iodine, and astatine form salts when chemically combined with a metal.
Bromine was discovered, at almost the same time in 1826, by two men, German chemist Carl Lowig (1803-90) and French chemist Antoine-Jerome Balard (1802-76).
While Balard announced his discovery first, Lowig had simply not completed his studies of the element when Balard made his announcement.

While he was still a student, Pasteur attracted the attention of Antoine Jerome Balard, the discoverer of the element bromine.
Instead of being sent to teach at a high-school in the provinces after his graduation, Pasteur became an assistant in the laboratory of Balard, where he had a chance to work on a doctor’s degree, and where he could talk with the best chemists in Paris.
Almost every Thursday, he was invited to the home of Professor Dumas, where the conversation was always about science.

This red liquid, which he brought along to Heidelberg, interested Gmelin greatly and he asked Löwig to study it in detail.
While Löwig was doing so, Antoine-Jerome Balard's account of his preparation of bromine from a concentrate of seawater and its identification as a new element appeared in the Annales de chimie et de physique in 1826.
Undeterred, Löwig, the "scooped" codiscoverer, continued his investigations of bromine and its compounds, discovering bromine hydrate, bromal hydrate, and bromoform, and writing a monograph, Bromine and Its Chemical Relations, in 1829.
