Carl Jacob Löwig (17 March 1803 – 27 March 1890) was a German chemist and discovered bromine independently of Antoine Jérôme Balard.
He received his PhD at the University of Heidelberg for his work with Leopold Gmelin.
During his research on mineral salts he discovered bromine in 1825, as a brown gas evolving after the salt was treated with chlorine.
In 1853, he was the first person to synthesize Tetraethyllead (Pb(C2H5)4).
After working at the University of Heidelberg and the University of Zurich he became the successor to Robert Wilhelm Bunsen at the University of Breslau. He worked and lived in Breslau until his death in 1890.
