Torsten W. Nordenfelt

The Swedish engineer Torsten Wilhelm Nordenfelt (1842-1920) teamed up with his fellow countryman and inventor Palmcrantz to produce the M1877 25mm/1in four-barrelled semi-automatic weapon for the Royal Swedish Navy. The gun was gravity fed and fired at 120 rpm. As the Royal Navy was the largest in the world in the late 19th century, Nordenfelt set up a factory in London to supply guns. He teamed up with Maxim to produce guns that were supplied to the Ottoman and German navies. In 1906 the US Navy adopted its first light automatic anti-aircraft gun, the Maxim-Nordenfelt 1 pdr Mark 6.
