By 1894, Haber worked at the University of Karlsruhe, researching methods to synthesize nitrogen. Articles from Britannica Encyclopedias for elementary and high school students.

Born in 1868 in Breslau, Germany (now part of Poland), Haber began studying chemistry at the age of 18 at the University of Heidelberg. Immunotherapy as a last resort for terminal cancer patients, US and South Korea reported first COVID cases on the same day. This poses an unacceptable risk when the gas leaking out is hydrogen; not to mention that no chemical plant can work with compressors that fail at least once a day. The process combines a single nitrogen molecule with 3 hydrogen molecules to produce 2 molecules of Ammonia. But by the beginning of the 20th century, guano deposits started to run out, and the price of the fertilizer began to increase. His collected meteorites and other mineral samples were loaned to Yale University, and eventually purchased by the Smithsonian.

Bosch was also very conscious of health and safety, and designed numerous quick-acting safety valves and other equipment so that the plant could be shut down and evacuated with record speed.

Omissions? Haber initially attempted to produce nitric oxide with the help of electric discharges, mimicking natural processes during a thunderstorm. “The solution appeared simple and was in fact so but yet the entire development of the process depended on it to a greater or lesser extent,” Bosch said. Yes, the use of biotechnology, GMOs or gene editing to develop antigens for treatments including vaccines are part of the solution.

Hydrogen was able to diffuse through the lining and was allowed to escape through grooves and holes in the jacket, to prevent a dangerous pressure build-up. Ammonia is then used as a fertilizer to dramatically increase crop yields. Carl Bosch, (born Aug. 27, 1874, Cologne, Germany—died April 26, 1940, Heidelberg), German industrial chemist who developed the Haber-Bosch process for high-pressure synthesis of ammonia and received, with Friedrich Bergius, the 1931 Nobel Prize for Chemistry for devising chemical high-pressure methods. The two have truly changed the world for the better. When Haber had made a similar attempt, the device failed after only a couple of hours of operation, so Bosch’s team designed a very sturdy, externally-heated contact tube as a reaction chamber. Research on this process involved the carrying out of more than 20,000 experiments, including an exhaustive search for catalysts among the metals and their compounds. The chemical equation for the Haber-Bosch process is N2 + 3H2 ⇌ 2NH3 The ⇌ arrow in the above equation implies that the reaction is reversible in nature. “Over the years we have been able to cull sufficient experience, especially during the war when the Oppau works were bombed night after night, and we are still of the opinion today that one cannot be too careful,” he said.

Throughout the 19th century, farmers used guano (i.e., the accumulated excrement of seabirds and bats) as highly effective fertilizer due to its exceptionally high content of nitrogen, phosphate and potassium—nutrients that are essential for plant growth. He also invented the Bosch process for preparing hydrogen on a manufacturing scale by passing a mixture of steam and water gas over a suitable catalyst at high temperature. Nearly 100 years on nothing much has changed, and the process is still used around the world. The media call it the “Insect Apocalypse”. That proved that commercial production was possible. Without the Haber-Bosch process we would only be able to produce around two-thirds the amount of food we do today. The two have created the “Haber-Bosch process,” which efficiently converts nitrogen from the air into ammonia (i.e., a compound of nitrogen and hydrogen).


The impact of Haber and Bosch’s work on global food production transformed the world forever.

The Haber–Bosch Process today consumes more than one percent of humanity's energy production and is responsible for feeding roughly one-third of its population. Indeed, Le Chatelier, who was the first to suggest fixing nitrogen under high pressure, gave up after a particularly hefty laboratory explosion. Haber next investigated high-temperature synthesis, with some success, and even succeeded in producing a small amount of nitrogen in 1905. However, Haber’s breakthrough occurred in a small tube, 75 centimeters tall and 13 centimeters in diameter.

Their lasting contribution to the well being of humanity means that they rightly deserve to be our second Heroes of Progress.

Without the combined efforts of Fritz Haber and Carl Bosch, the world’s population would be much smaller than it is today.
