Acetylene of 180°. Acetylene was discovered in 1836 by Edmund Davy, who identified it as a "new carburet of hydrogen". It was rediscovered in 1860 by French chemist Marcellin Berthelot, who coined the name "acétylène". Berthelot's empirical formula for acetylene (CH), as well as the alternative name "quadricarbure d'hydrogène" ("hydrogen quadricarbide"), were incorrect because chemists at that time used the wrong atomic mass for carbon (6 instead of 12). Berthelot was able to prepare this gas by passing vapours of organic compounds (methanol, ethanol, etc.) through a red-hot tube and collecting the effluent. He also found that acetylene was formed by
Martin Richards (computer scientist) Martin Richards (computer scientist) Martin Richards (born 21 July 1940) is a British computer scientist known for his development of the BCPL programming language which is both part of early research into portable software, and the ancestor of the B programming language invented by Ken Thompson in early versions of Unix and which Dennis Ritchie in turn used as the basis of his widely used C programming language. Richards studied mathematics as an undergraduate student at the University of Cambridge and took the Cambridge Diploma in Computer Science. His PhD was on programming language design and implementation. He was a
