Question: When was the country where Leon Diguet was educated invaded by Germany in WWII?

full_context: Document 1: Italian invasion of France: The Italian invasion of France, also called the Battle of the Alps (10–25 June 1940), was the first major Italian engagement of World War II and the last major engagement of the Battle of France.
Document 2: Louis-Charles Malassez: He studied medicine in Paris, where he worked as an "interne" from 1867. He served with the 5th Ambulance Corps during the Franco-Prussian War, afterwards returning to Paris, where he worked with distinguished physicians that included Claude Bernard, Jean-Martin Charcot and Pierre Potain. In 1875, he attained the chair of anatomy at Collège de France, and in 1894, became a member of the "Académie de Médecine".
Document 3: Race (human categorization): In the last two decades of the 18th century, the theory of polygenism, the belief that different races had evolved separately in each continent and shared no common ancestor, was advocated in England by historian Edward Long and anatomist Charles White, in Germany by ethnographers Christoph Meiners and Georg Forster, and in France by Julien-Joseph Virey. In the US, Samuel George Morton, Josiah Nott and Louis Agassiz promoted this theory in the mid-nineteenth century. Polygenism was popular and most widespread in the 19th century, culminating in the founding of the Anthropological Society of London (1863) during the period of the American Civil War, in opposition to the Ethnological Society, which had abolitionist sympathies.
Document 4: Nicolas-Joseph Thiéry de Menonville: Nicolas-Joseph Thiéry de Menonville (Saint-Mihiel, France, 18 June 1739 – Port-au-Prince, Saint-Domingue, 1780), "avocat" at the "Parlement of Paris", was a French botanist who volunteered to be sent to Mexico in 1776 to steal the cochineal insect valued for its scarlet dye. In his clandestine bioprospecting piracy, he worked without official papers and would have been ruthlessly treated had he been caught. He succeeded in naturalizing the insect and the prickly pear ("Opuntia") "nopal" cactus on which it depended in the French colony of Saint-Domingue.
Document 5: Anthropology: 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. Various short-lived organizations of anthropologists had already been formed. The Société Ethnologique de Paris, the first to use Ethnology, was formed in 1839. Its members were primarily anti-slavery activists. When slavery was abolished in France in 1848 the Société was abandoned.
Document 6: Anthropology: Some authors argue that anthropology originated and developed as the study of "other cultures", both in terms of time (past societies) and space (non-European/non-Western societies). For example, the classic of urban anthropology, Ulf Hannerz in the introduction to his seminal Exploring the City: Inquiries Toward an Urban Anthropology mentions that the "Third World" had habitually received most of attention; anthropologists who traditionally specialized in "other cultures" looked for them far away and started to look "across the tracks" only in late 1960s.
Document 7: Robert Jameson: As Regius Professor of Natural History at the University of Edinburgh for fifty years, Jameson is notable for his advanced scholarship, his superb museum collection and for his tuition of Charles Darwin. Jameson was not at his best in the lecture theatre however, and, for the first half of his career, he grappled with his predecessor John Walker's perverse "Neptunian" geological theories. Darwin attended Robert Jameson's natural history course at the University of Edinburgh in his teenage years, learning about stratigraphic geology and assisting with the collections of the Museum of Edinburgh University, then one of the largest in Europe. At Jameson's Wernerian Natural History Association, the young Charles Darwin saw John James Audubon give a demonstration of his method of using wires to prop up birds to draw or paint them in natural positions. Robert Jameson was the great-uncle of Sir Leander Starr Jameson, Bt, KCMG, CB, British colonial official and inspiration for the "Jameson Raid".
Document 8: Battle of France: The Battle of France, also known as the Fall of France, was the German invasion of France and the Low Countries during the Second World War. In six weeks from 10 May 1940, German forces defeated Allied forces by mobile operations and conquered France, Belgium, Luxembourg and the Netherlands, bringing land operations on the Western Front to an end until 6 June 1944. Italy entered the war on 10 June 1940 and attempted an invasion of France.
Document 9: Military history of the United States during World War II: The war against Germany involved aid to Britain, her allies, and the Soviet Union, with the U.S. supplying munitions until it could ready an invasion force. U.S. forces were first tested to a limited degree in the North African Campaign and then employed more significantly with British Forces in Italy in 1943 -- 45, where U.S. forces, representing about a third of the Allied forces deployed, bogged down after Italy surrendered and the Germans took over. Finally the main invasion of France took place in June 1944, under General Dwight D. Eisenhower. Meanwhile, the U.S. Army Air Forces and the British Royal Air Force engaged in the area bombardment of German cities and systematically targeted German transportation links and synthetic oil plants, as it knocked out what was left of the Luftwaffe post Battle of Britain in 1944. With the Soviets unstoppable in the east, and the Allies unstoppable in the west, Germany was squeezed to death. Berlin fell to the Soviets in May 1945, and with Adolf Hitler dead, the Germans surrendered.
Document 10: Battle of Dunkirk: The Battle of Dunkirk was a military operation that took place in Dunkirk (Dunkerque), France, during the Second World War. The battle was fought between the Allies and Nazi Germany. As part of the Battle of France on the Western Front, the Battle of Dunkirk was the defence and evacuation to Britain of British and other Allied forces in Europe from 26 May to 4 June 1940.
Document 11: Léon Diguet: 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. 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. During that period, he explored the peninsula's interior, collecting natural history specimens for the National Museum of Natural History in Paris. Afterwards, from 1893 to 1914, he made six more trips to Mexico as an explorer and collector:
Document 12: World War II: The Empire of Japan aimed to dominate Asia and the Pacific and was already at war with the Republic of China in 1937, but the world war is generally said to have begun on 1 September 1939 with the invasion of Poland by Nazi Germany and subsequent declarations of war on Germany by France and the United Kingdom. Supplied by the Soviet Union, from late 1939 to early 1941, in a series of campaigns and treaties, Germany conquered or controlled much of continental Europe, and formed the Axis alliance with Italy and Japan. Under the Molotov -- Ribbentrop Pact of August 1939, Germany and the Soviet Union partitioned and annexed territories of their European neighbours, Poland, Finland, Romania and the Baltic states. The war continued primarily between the European Axis powers and the coalition of the United Kingdom and the British Commonwealth, with campaigns including the North Africa and East Africa campaigns, the aerial Battle of Britain, the Blitz bombing campaign, and the Balkan Campaign, as well as the long - running Battle of the Atlantic. On 22 June 1941, the European Axis powers launched an invasion of the Soviet Union, opening the largest land theatre of war in history, which trapped the major part of the Axis military forces into a war of attrition. In December 1941, Japan attacked the United States and European colonies in the Pacific Ocean, and quickly conquered much of the Western Pacific.
Document 13: Anthropology: Similar organizations in other countries followed: The American Anthropological Association in 1902, the Anthropological Society of Madrid (1865), the Anthropological Society of Vienna (1870), the Italian Society of Anthropology and Ethnology (1871), and many others subsequently. The majority of these were evolutionist. One notable exception was the Berlin Society of Anthropology (1869) founded by Rudolph Virchow, known for his vituperative attacks on the evolutionists. Not religious himself, he insisted that Darwin's conclusions lacked empirical foundation.
Document 14: Museum of Almería: The first attempt at the creation of the Museum of Almería dates back to the 19th century. In 1880 the Belgian engineer Luis Siret found the most famous prehistoric site in this region. Due to his archaeological researches, he developed a significant collection of ancient pieces which he finally donated to the National Archeological Museum, with the desire that one part of the collection stays in Almería. The conditions were agreed during the Second Spanish Republic when the archeological museum was opened. There were two small rooms which were handed over by the “Escuela de Artes y Oficios” in 1934 but this collection didn’t have the pieces that Louis Siret had hoped would remain in Almería. After a lot of difficulties which took place throughout the years, 2006 was the year that the museum finally settled into its new place.
Document 15: Anthropology: During the last three decades of the 19th century a proliferation of anthropological societies and associations occurred, most independent, most publishing their own journals, and all international in membership and association. The major theorists belonged to these organizations. They supported the gradual osmosis of anthropology curricula into the major institutions of higher learning. By 1898 the American Association for the Advancement of Science was able to report that 48 educational institutions in 13 countries had some curriculum in anthropology. None of the 75 faculty members were under a department named anthropology.
