a German chemist, is best known for his work on the fixation of nitrogen from air and the synthesis of ammonia from the process. Such a discovery won him the Nobel Prize in Chemistry in 1918, and decreased Germany’s dependence on Chili’s ammonia during World War I, who used it primarily for fertilization and explosives. Haber also spent some time studying energy inefficiencies in steam engines, turbines, and motors driven by fuel, and sought ways of reducing the loss of energy through electrochemical means. He, however, did not succeed in finding a commercially viable way to decrease energy waste, but during his research produced the combustion of carbon monoxide and hydrogen. His research into combustion began early when he first wrote his 1986 thesis on his experiments with decomposition and combustion of hydrocarbons. In addition to his research, Haber invented the glass electrode, which is still used today.
