Gem stones, such as aquamarine, emerald, and beryl contain beryllium and have been recognized since ancient times. But beryllium, as an element, was first discovered in 1798 by the French chemist, Vauquelin and reduced to its metallic form; subsequently, it was named beryllium in 1828 by the German metallurgist, Wohler. Beryllium became a commercial product when it was used as an alloy first with aluminum and later with copper, nickel, and cobalt after World War I. The industry grew in the 1930s due to the increased use of beryllium–copper products during World War II and the use of beryllium oxide in the refractory and fluorescent lamp industries. During and after World War II, beryllium was used in the nuclear industry because of its ability to function as a neutron multiplier. Beryllium was used for both civilian nuclear reactors and for military weapons.
