Bromine was discovered by two scientists working independently. In the Autumn of 1825, student K. Lowig took a bottle of a reddish liquid with an unpleasant smell to the Laboratory of Medicine and Chemistry of Prof. L. Gemlin, at the University of Heidelberg. Lowig told Gemlin that the liquid, of mineral origin, resulted from the treatment with gaseous chlorine, thus explaining the red color. The substance responsible for that red color was extracted with the help of ether, giving origin to a pink liquid later known as bromine.
