Question: When was the first establishment that owns Hamburger University built in the country where Leon Diguet was educated?

<P0-S0> some historians concur that a&w, which opened in 1921 and began franchising in 1923, was the first fast food restaurant (e. tavares). <P0-S1> thus, the american company white castle is sometimes considered the second fast - food outlet in wichita, kansas in 1921, selling hamburgers for five cents apiece from its inception and spawning numerous competitors and emulators. <P0-S2> what is certain, however, is that white castle made the first significant effort to standardize the food production in, look of, and operation of fast - food hamburger restaurants. <P0-S3> william ingram's and walter anderson's white castle system created the first fast food supply chain to provide meat, buns, paper goods, and other supplies to their restaurants, pioneered the concept of the multi-state hamburger restaurant chain, standardized the look and construction of the restaurants themselves, and even developed a construction division that manufactured and built the chain's prefabricated restaurant buildings. <P0-S4> the mcdonald's speedee service system and, much later, ray kroc's mcdonald's outlets and hamburger university all built on principles, systems and practices that white castle had already established between 1923 and 1932. <SEP> <P1-S0> During that period, he explored the peninsula's interior, collecting natural history specimens for the National Museum of Natural History in Paris. <P1-S1> He studied science at the Muséum national d'histoire naturelle in Paris, where he was influenced by scientists that included biologist Jean Louis Armand de Quatrefages de Bréau, zoologist Alphonse Milne-Edwards, and anthropologist Ernest Hamy. <P1-S2> From 1889 to 1892, he was employed as a chemical engineer at the French-owned El Boleo mining installation in Santa Rosalia, Baja California Sur. <P1-S3> Afterwards, from 1893 to 1914, he made six more trips to Mexico as an explorer and collector: <SEP> <P2-S0> Hamburger University is a training facility of McDonald's, located in Chicago, Illinois. <P2-S1> This corporate university was designed to instruct personnel employed by McDonald's in the various aspects of restaurant management. <P2-S2> More than 80,000 restaurant managers, mid-managers and owner-operators have graduated from the university. <SEP> <P3-S0> Sporadic use of the term for some of the subject matter occurred subsequently, such as the use by Étienne Serres in 1838 to describe the natural history, or paleontology, of man, based on comparative anatomy, and the creation of a chair in anthropology and ethnography in 1850 at the National Museum of Natural History (France) by Jean Louis Armand de Quatrefages de Bréau. <P3-S1> Various short-lived organizations of anthropologists had already been formed. <P3-S2> The Société Ethnologique de Paris, the first to use Ethnology, was formed in 1839. <P3-S3> Its members were primarily anti-slavery activists. <P3-S4> When slavery was abolished in France in 1848 the Société was abandoned. <SEP> <P4-S0> 1972: The first McDonald's in France opens, in Créteil, even though the company officially recognizes the first outlet in Strasbourg in 1979. <SEP> <P5-S0> in the same year that the university of hamburg was founded, otto lauffer was granted the first professorship in folklore in germany, which he retained until 1939. in 1922/23, he was also rector of the university.
