Extractions: German physical chemist. Haber-Bosch process for making ammonia. Intensely patriotic, he directed Germany's World War I chemical-warfare efforts, under which poison gas was introduced. His versatility and his wide-ranging and important work brought him fame and honour, and he was awarded a 1918 Nobel Prize. In 1933 the Nazi Party's anti-Semitic policies led him to resign as head (since 1911) of the Kaiser-Wilhelm Institute. var mm = [["Jan.","January"],["Feb.","February"],["Mar.","March"],["Apr.","April"],["May","May"],["June","June"],["July","July"],["Aug.","August"],["Sept.","September"],["Oct.","October"],["Nov.","November"],["Dec.","December"]]; To cite this page: MLA style: "Haber, Fritz."

The Present-Day Significance of Fritz Haber BY MORRIS GORAN Roosevelt College, Chicago It is surprising not to find Fritz Haber more popular in America, for he was the type of scientist who could be more idolized in the United States than he was in Germany. Besides possessing what might be called Yankee ingenuity, Haber had the practical insight, the grasp of theory, and the unfettered imagination sufficient to place him with the celebrated of any country during any period. His significance today lies not so much in this posthumous straddling of time and space, as it does in his prophetic vision and penetrating analyses. Haber has rightfully been called "the greatest authority in the world on the relations between scientific research and industry."
Haber Process: Ammonia Production haber Process for the Production of Ammonia. In 1909 fritz haber established the conditions under which nitrogen, N2(g), and hydrogen, H2(g), would combine http://www.ausetute.com.au/haberpro.html
Extractions: Osmium is a much better catalyst for the reaction but is very expensive. This process produces an ammonia, NH (g), yield of approximately 10-20%. The Haber synthesis was developed into an industrial process by Carl Bosch. The reaction between nitrogen gas and hydrogen gas to produce ammonia gas is exothermic , releasing 92.4kJ/mol of energy at 298K (25 o C). N (g) ammonia + 92.4 kJ mol By Le Chetalier's Principle increasing the pressure causes the equilibrium position to move to the right resulting in a higher yeild of ammonia since there are more gas molecules on the left hand side of the equation (4 in total) than there are on the right hand side of the equation (2). Increasing the pressure means the system adjusts to reduce the effect of the change, that is, to reduce the pressure by having fewer gas molecules. decreasing the temperature causes the equilibrium position to move to the right resulting in a higher yield of ammonia since the reaction is exothermic (releases heat). Reducing the temperature means the system will adjust to minimise the effect of the change, that is, it will produce more heat since energy is a product of the reaction, and will therefore produce more ammonia gas as well

Extractions: Fritz Haber (1868-1934) German chemist, winner of the Nobel Prize of Chemistry in 1918, for the synthesis of ammonia from its elements. Fritz Haber was born in Bresla, in December 9th 1868, and died in Basle, Switzerland, in January 29th, 1934. Haber studied in Berlin, Heidelberg, Charlottenburg and Karlsruhe. Taught Chemistry in the High Technique School of Karlsruhe until 1911, when he went to Berlin, as professor of Chemical-Physics at the University of Berlin and later as director of the Chemical-Physics Institute Kaiser Wilhelm. The research work made by Haber (1905-1911) on the equilibrium between nitrogen hydrogen and ammonia established the exact temperature and pressure, as well as the catalyst, that optimized the ammonia formation. Ammonia produced through this method could be transformed in nitric acid by oxidation, using the Ostwald process. This acid was then used in producing explosives and fertilizers. Carl Bosh developed the industrial stages for the Haber process. The perfection of the Haber-Bosh process encouraged Germany to enter in World War I. During the war, Haber led the chemical war and headed the first attack with chlorine gas in Ypres (1915). Hitler's regime ordered his exile due to his Jewish origins.

Extractions: photo of Fritz Haber with Albert Einstein Although a number of reports credit Fritz Haber with the synthesis MDMA in 1891, Haber gained greatest recognition for his work on the fixation of nitrogen from air. Fritz Haber won the Nobel Prize in 1918 for the "synthesis of ammonia from its elements". The award of the prize was controversial. As head of the German Chemical Warfare Service during WWI, Haber had convinced the German Imperial Army to use gas-weapons he had devised as a means of breaking through Allied front-lines. Today, readers of the popular press and even mainstream scientific literature might find it hard to decide whether poison-gas or the deadly neurotoxin Ecstasy/MDMA pose a greater threat to human health.

Extractions: Fritz Haber He was born in Breslau, Germany Nobel Prize in Chemistry for this work. The Haber-Bosch process was a milestone in industrial chemistry, because it divorced the production of nitrogen products, such as fertilizer, explosives and chemical feedstocks, from natural deposits, especially sodium nitrate ('Caliche'), of which Chile was a major producer. The sudden availability of cheap nitrogenous fertilizer is credited with averting a Malthusian catastrophe, or population crisis. He was also active in the research of combustion reactions, the separation of gold from sea water, adsorption effects, and electrochemistry. A large part of his work from 1911 to was done at the Institute for Physical and Electrochemistry at Berlin-Dahlem. Haber played a major role in the development of chemical warfare in World War I. Part of this work included the development of gas masks with absorbant filters. Gas warfare in WWI was, in a sense, the war of the chemists, with Haber pitted against French Nobel laureate chemist Victor Grignard. His wife opposed his work on poison gas and committed suicide with his service weapon after he personally oversaw the first use of chlorine in Ypres. In his studies of the effects of poison gas, Haber found a simple mathematical relationship between the concentration (C) of the gas and the amount of time (t) it was breathed in, expresed as C x t = k, where k is a constant. In other words, exposure to a low level of gas for a long time can cause the same result (e.g. death) as exposure to a high concentration for a short time. This relationship is known as Haber's rule. Haber defended gas warfare against accusations that it was inhumane, saying that death was death, by whatever means it was inflicted. In the 1920s, he developed the cyanide gas formualtion

Extractions: He was born on December 9,1868 in Breslau, Germany. He was the son of a prosperous German chemical merchant Siegfried Haber and Paula Haber; his mother died during childbirth. He was an only child during his first nine years of his life, and then his father married again. Fritz came to love his stepmother and as an expression of his feeling gave her white lilacs every Christmastime. Fritz has three sisters that gave him affection, even though he always was ten years older than his eldest stepsister. When he was old enough for formal schooling, Fritz was enrolled at the Volksschule, or formal school. After three years he went to the St. Elizabeth Gymnasium for nine years. The curriculum there centered about the humanities. The students were required to learn Latin, Greek, Literature, and Philosophy. The little science taught was a mixture of religion, philosophy, and nature study called history. As a consequence, Fritz developed an interest in literature and philosophy that he maintained throughout his life. Gothie became his favorite poet and Kant his favorite philosopher. Men in Fritz Haber generation believe very strongly in progress and enlightenment through the acquisition of culture. Fritz enrolled in the University of Berlin when he was almost eighteen years old. The university was the home of scientist and scholars as Helmhots who was a lucid thinker about the philosophy and methodology of science as well as physicist and physiologist.

Vaclav Smil admits in the postscript of this book that he had planned originally to write a biography of Fritz Haber. He does in fact include a summary of both Haber's and Carl Boschs lives in the postscript, but the book itself is dedicated to the discovery, marketing, and consequences of the synthesis of ammonia. The book is interdisciplinary; with individual chapters being of interest to specific groups, but with its historical overview will appeal to a wide group of readers. Enriching the Earth follows Smils previous books that address the world's energy needs, ecology, and food production. The goal of his previous work

"It's possible to walk in Fritz Haber's footsteps without knowing it, for the trail is rarely marked." So Daniel Charles begins Master Mind: The Rise and Fall of Fritz Haber, the Nobel Laureate Who Launched the Age of Chemical Warfare , inviting readers to explore a nearly forgotten pathway that leads to where, exactly?
Extractions: Photo by Jeff Cleary A few months ago when many people feared that the attack on the Twin Towers of the World Trade Center would be followed soon by terrorist attacks with chemical, biological, and nuclear weapons, I remembered one of my biochemistry lectures in Berlin several years ago. On a dark and cold evening, our professor, a neurochemist, decided to take us for a walk and tell us about the history of the surrounding institutes. Just a few steps from the lecture hall, we stopped in front of the Fritz Haber Institute of Physical Chemistry, one of Berlin's Max Planck Institutes. Fritz Haber, a brilliant scientist in the field of physical chemistry, found a way to fix nitrogen from the air. Under high pressure and in the presence of a catalyst, nitrogen and hydrogen gas react to produce ammonia. Haber's colleague Carl Bosch later adjusted the reaction conditions for large-scale use in the chemical industry. Suddenly, massive quantities of fertilizers could be produced, and importing guano from remote places such as South America became unnecessary. Haber was awarded the Nobel Prize in chemistry in 1918. Bosch (along with Friedrich Bergius) received the same award in 1931. Haber, who considered himself a German patriot, was already a prominent scientist and the director of the Kaiser Wilhelm Institute of Physical Chemistry in Berlin (now the Fritz Haber Institute) when World War I broke out. Before the war, Germany's emperor, Wilhelm II, had ruled his country with an iron fist. He entered a maritime arms race with the U.K. and was trying to turn his country into a colonial empire. During this period, Wilhelm's generals brutally crushed the Hereo uprising in the new German colony of Namibia and the Boxer rebellion in China, where Germany possessed the small colony of Qingdao (Tsingtao). Despite all this, Fritz Haberalong with many members of the German elitelent his support to Emperor Wilhelm II and the German army.
