He took brine (sea water in which salts have been concentrated by evaporation of water) and crystallized salt from it. Lðwig had taken water from a salt spring in Bad Kreuznach and added chlorine to the liquid. The next name in the story of bromine is Carl Lðwig (Loewig), who discovered bromine in 1825, while still a chemistry student at Heidelberg University, Germany. an element, not a compound.
