Eduard Rubin

Eduard Alexander Rubin (17 July 1846 – 6 July 1920) was a Swiss mechanical engineer and artillery officer. Rubin has been credited with the development of the full metal jacket bullet in 1882. However, the earliest documented development of the design is attributed to Oberstleutnant , who produced an unsoldered copper-jacketed bullet in 1876. Rubin developed the 7.5×55mm Swiss cartridge, the Schmidt-Rubin rifle, the ignition mechanism and the use of TNT and ammonium nitrate to replace gunpowder in artillery shells. Rubin's fully copper clad bullets were also the inspiration for the full metal jacket bullets introduced in 1886 for the Lebel rifle.
