Léon Guillet
Léon Alexandre Guillet (11 July 1873 – 9 May 1946) was a French metallurgist who studied the properties of metal alloys and developed martensitic and austenitic stainless steels. He served as a professor of metallurgy at the École Centrale Paris where he was a director from 1923 and played a key role in putting materials research on a scientific footing. Guillet was born in Saint Nazaire (Loire Atlantique) and in 1894 he went to the school of art and manufacture where he met Henri Le Chatelier who guided him. His doctoral thesis was on aluminium alloys and the work was done at Dion-Bouton and at Le Chatelier's laboratory in the Ecole des Mines. He then became a consultant at Dion-Bouton and worked with several companies. In 1906 he went to teach metallurgy and became a full professor in 1908 and worked there until 1942 while also consulting in the industry. In 1923 he became director of the school of arts and manufacture where he brought major changes including a foundation in ...

École Centrale Paris
École Centrale Paris (ECP; also known as École Centrale or Centrale) was a French grande école in engineering and science. It was also known by its official name ''École Centrale des Arts et Manufactures''. In 2015, École Centrale Paris merged with Supélec to form CentraleSupélec, a constituent college of the University of Paris-Saclay. Founded in 1829, it was among the most prestigious and selective grandes écoles. Rooted in rich entrepreneurial tradition since the industrial revolution era, it served as the cradle for top-level engineers and executives who continue to constitute a major part of the industry leadership in France. Since the 19th century, its model of education for training generalist engineers inspired the establishment of several engineering institutes around the world, such as the École Polytechnique Fédérale de Lausanne in Switzerland, Faculté polytechnique de Mons in Belgium, as well as other member schools of the Ecole Centrales Group alliance ...

Saint-Nazaire
Saint-Nazaire (; ; Gallo: ''Saint-Nazère/Saint-Nazaer'') is a commune in the Loire-Atlantique department in western France, in traditional Brittany. The town has a major harbour on the right bank of the Loire estuary, near the Atlantic Ocean. The town is at the south of the second-largest swamp in France, called "la Brière". Given its location, Saint-Nazaire has a long tradition of fishing and shipbuilding. The Chantiers de l'Atlantique, one of the largest shipyards in the world, constructed notable ocean liners such as , , and the cruise ship , the largest passenger ship in the world until 2022. Saint-Nazaire was a small village until the Industrial Revolution but became a large town in the second half of the 19th century, thanks to the construction of railways and the growth of the seaport. Saint-Nazaire progressively replaced upstream Nantes as the main haven on the Loire estuary. As a major submarine base for the Kriegsmarine, Saint-Nazaire was subject to a succes ...

Henry Louis Le Chatelier
Henry Louis Le Chatelier (; 8 October 1850 – 17 September 1936) was a French chemist of the late 19th and early 20th centuries. He devised Le Chatelier's principle, used by chemists and chemical engineers to predict the effect a changing condition has on a system in chemical equilibrium. Early life Le Chatelier was born on 8 October 1850 in Paris and was the son of French materials engineer Louis Le Chatelier and Louise Durand. His father was an influential figure who played important roles in the birth of the French aluminium industry, the introduction of the Martin-Siemens processes into the iron and steel industries, and the rise of railway transportation. Le Chatelier's father profoundly influenced his son's future. Henry Louis had one sister, Marie, and four brothers, Louis (1853–1928), Alfred (1855–1929), George (1857–1935), and André (1861–1929). His mother raised the children by regimen, described by Henry Louis: "I was accustomed to a very strict discipline: ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
