Fritz Haber (German pronunciation: [ˈfʁɪt͡s ˈhaːbɐ] (); 9 December 1868 - 29 January 1934) was a German chemist who received the Nobel Prize in Chemistry in 1918 for his invention of the Haber-Bosch process, a method used in industry to synthesize ammonia from nitrogen gas and hydrogen gas. This invention is important for the large-scale synthesis of fertilizers and explosives.

Abstract. Gold is considered a store of value and has been a sought-after metal since the dawn of human civilization. It was known to Egyptians as early as 3100 BC. The value of gold was reported to be two-and-one-half times the value of silver in the code of Menes, the founder of the first Egyptian dynasty. A gold mine in Nubia in Nile valley ...

Haber was also active in the research on combustion reactions, the separation of gold from sea water, adsorption effects, electrochemistry, and free radical research (see Fenton's reagent ). A large part of his work from 1911 to 1933 was done at the Kaiser Wilhelm Institute for Physical Chemistry and Electrochemistry at Berlin-Dahlem.

For Haber, it was just a matter of extracting the gold to create a whole new source of wealth for Germany—one that would continue on well past the time their debt was paid. According to his original calculations, Haber figured that one metric ton of seawater would contain about 65 milligrams of gold. That in turn meant that every cubic mile ...
