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 cooper, nickel, and cobalt after World War I. This commercial product was used in communications (telephones and telecommunication) and medicine (x-ray devices). The industry grew in the 1930s due to the increased use of beryllium–copper products during World War II in defense (military equipment), nuclear energy (nuclear reactors), and household items (fluorescent lamp industries).
