Calcium carbide and acetylene were first produced by Edmund Davy in England in 1836, though their true chemical makeup was not known until much later. Acetylene was given its name by the French chemist Marcelin Berthelot in 1860 and calcium carbide was first identified in 1862 by the German chemist Friedrich Wöhler. However, both materials remained laboratory curiosities until 1892 when ...
