Question: After whom was the defence installation of which, Ouvrage Le Lavoir is a part named ?

full_context: Document 1: Ouvrage Le Lavoir: Ouvrage Le Lavoir Is a work ("gros ouvrage") of the Maginot Line's Alpine extension, the Alpine Line, also called the Little Maginot Line. The ouvrage consists of two entry blocks, one infantry block, three artillery blocks and one observation block 6 km south of Modane, France, guarding the Col de Fréjus. The surface barracks at Le Lavoir were connected to Charmaix by an aerial tram.
Document 2: Ouvrage Bréhain: Ouvrage Bréhain is part of the Fortified Sector of the Crusnes of the Maginot Line, located near the community of Bréhain-la-Ville in the Meurthe-et-Moselle "département" of France. Bréhain is flanked by "petits ouvrages" Mauvais Bois and Aumetz. The "gros ouvrage" was equipped with long-range artillery, and faced the border with Luxembourg. It saw no major action in either the Battle of France in 1940 or the Lorraine Campaign of 1944. While not open to public visitation, it has been secured and is in relatively good condition when compared to other abandoned Maginot positions. A flanking casemate has been restored and may be visited.
Document 3: Ouvrage Bois-du-Four: Ouvrage Bois-du-Four is a lesser work ("petit ouvrage") in the Fortified Sector of the Crusnes of the Maginot Line. The ouvrage consists of a single large combat block without an underground gallery system, and is located between "petit ouvrage" Mauvais-Bois and "gros ouvrage" Bréhain, facing Luxembourg. A planned expansion, never carried out, was intended to enlarge Bois-du-Four into a fully equipped "gros ouvrage". Bois-du-Four saw little action in either the Battle of France in 1940 or the Lorraine Campaign of 1944. It is preserved by the community of Villers-la-Montagne and may be visited.
Document 4: Königsberg fortifications: The fortifications of the former East Prussian capital Königsberg (now Kaliningrad) consist of numerous defensive walls, forts, bastions and other structures. They make up the First and the Second Defensive Belt, built in 1626—1634 and 1843—1859, respectively. The 15 metre-thick First Belt was erected due to Königsberg's vulnerability during the Polish–Swedish wars. The Second Belt was largely constructed on the place of the first one, which was in a bad condition. The new belt included twelve bastions, three ravelins, seven spoil banks and two fortresses, surrounded by water moat. Ten brick gates served as entrances and passages through defensive lines and were equipped with moveable bridges.
Document 5: Moselle-Line: The Moselle-Line was the designation of a line of French barrier forts ("forts d'arrêt") on the upper Moselle between the fortresses of Épinal and Belfort.
Document 6: Fortified Sector of Rohrbach: The Fortified Sector of Rohrbach ("Secteur Fortifié de Rohrbach") was the French military organization that in 1940 controlled the section of the Maginot Line in the vicinity of Bitche. The sector was bordered to the west by the Fortified Sector of the Sarre and to the east by the Fortified Sector of the Vosges. With lower priority than other sectors, the SF Rohrbach was built somewhat later than its neighbors to the east and west, and in company with positions on the extreme western end of the Maginot Line, became one of the "New Fronts." The sector contains several major "ouvrages" and was the scene of fighting in both 1940 and 1944. It was attacked in 1940 by German forces in the Battle of France. The sector was heavily engaged by German forces in mid-June 1940, with several casemates and the "petit ouvrage" Welschhof surrendering before the Second Armistice at Compiègne. The remaining positions and their garrisons finally surrendered on 27 June 1940. In 1944 German forces occupied several positions in the SF Rohrbach, forcing advancing American forces to attack them individually or to bypass them. The German Operation Nordwind offensive of early 1945 caused American forces to fall back, returning to complete the capture of the Rohrbach sector in March 1945. Following the war many positions were reactivated for use during the Cold War. Two locations are now preserved and open to the public.
Document 7: Winter Line: The Winter Line was a series of German and Italian military fortifications in Italy, constructed during World War II by Organisation Todt and commanded by Albert Kesselring. The series of 3 lines was designed to defend a western section of Italy, focused around the town of Monte Cassino, through which ran the important Highway 6 which led uninterrupted to Rome. The primary Gustav Line ran across Italy from just north of where the Garigliano River flows into the Tyrrhenian Sea in the west, through the Apennine Mountains to the mouth of the Sangro River on the Adriatic coast in the east. The two subsidiary lines, the Bernhardt Line and the Hitler Line ran much shorter distances from the Tyrrehnian sea to just North East of Cassino where they would merge into the Gustav Line. Relative to the Gustav Line, the Hitler Line stood to the North-West and the Bernhardt Line to the South-East of the primary defenses.
Document 8: Barbara Line: During the Italian Campaign of World War II, the Barbara Line was a series of German military fortifications in Italy, some 10 - south of the Gustav Line, from Colli al Volturno to the Adriatic Coast in San Salvo and a similar distance north of the Volturno Line. Near the eastern coast, it ran along the line of the Trigno river. The line mostly consisted of fortified hilltop positions.
Document 9: Maginot Line: The Maginot Line (French: "Ligne Maginot" , ] ), named after the French Minister of War André Maginot, was a line of concrete fortifications, obstacles, and weapon installations built by France in the 1930s to deter invasion by Germany. Constructed on the French side of its borders with Switzerland, Germany, and Luxembourg, the line did not extend to the English Channel because the French military did not want to offend neutral Belgium.
Document 10: Ouvrage Pas du Roc: Ouvrage Pas du Roc is a work ("gros ouvrage") of the Maginot Line's Alpine extension, the Alpine Line. The ouvrage consists of one entry blocks, one infantry block, two artillery blocks and one observation block 6 km south of Modane and 1.6 km east of Ouvrage Le Lavoir in the vicinity of the Col de Fréjus. The position was incomplete at the outbreak of war in 1940.
Document 11: Gothic Line: The Gothic Line (German: "Gotenstellung" ; Italian: "Linea Gotica" ) was a German defensive line of the Italian Campaign of World War II. It formed Field Marshal Albert Kesselring's last major line of defence along the summits of the northern part of the Apennine Mountains during the fighting retreat of the German forces in Italy against the Allied Armies in Italy, commanded by General Sir Harold Alexander.
Document 12: Ouvrage Otterbiel: Ouvrage Otterbiel forms part of the Maginot Line in the Fortified Sector of Rohrbach, Sub-sector of Bitche, and is located on the "Camp de Bitche" of the French Army. It is located between "gros ouvrage" Schiesseck and "petit ouvrage" Grand Hohekirkel. Part of the Fortified Sector of Rohrbach, the "petit ouvrage" comprises four combat blocks and an entry block. Due to budget restrictions, a planned flanking infantry block was never constructed. Otterbiel saw no significant action in the Battle of France, and limited action during the 1944/45 Lorraine Campaign. It was renovated for use during the Cold War. Otterbiel is used for ammunition storage by the French Army.
Document 13: Ouvrage Simserhof: Ouvrage Simserhof is a "gros ouvrage" of the Maginot Line, located near the community of Sierstal in the French "département" of Moselle. Simserhof is adjoined by "petit ouvrage" Rohrbach and "gros ouvrage" Schiesseck, and faces the German frontier. Located 4 km to the west of Bitche, the "ouvrage" derived its name from a nearby farm. It was a part of the Fortified Sector of Rohrbach. During the Battle of France in 1940, Simserhof supported its neighboring fortifications with covering artillery fire, with partial success. After the surrender of France, it was occupied by the Germans as a storage depot for torpedoes, and later resisted the American advances of late 1944. Taken by the Americans, it was briefly re-occupied by the Germans during Operation Nordwind. Following the war it was repaired for use by the French Army, but was proposed as a museum of the Maginot Line as early as the 1960s. Retained by the Ministry of Defense, Simserhof now functions as a museum, and has the most extensive visitor infrastructure of any of the preserved Maginot fortifications.
Document 14: Flaine: Flaine is a ski area in the Haute Savoie region of the French Alps, and is a part of the linked Grand Massif domain. It is in the territory of the communes of Magland and Arâches-la-Frasse. Flaine is linked to Samoëns, Morillon, Les Carroz and Sixt-Fer-à-Cheval, with 267 km of pistes in total. It featured the first 8-seater high speed chairlift, Les Grands Vans, and the first snow cannons to be installed in Europe. Flaine is often called the "big snowy bowl" due to it having one of the best snow records in the Alps. It is a modern, car-free resort with a wealth of amenities, all within close proximity to the accommodation.
Document 15: Battle of the Frontiers: The Battle of the Frontiers was a series of battles fought along the eastern frontier of France and in southern Belgium shortly after the outbreak of World War I. The battles resolved the military strategies of the French Chief of Staff General Joseph Joffre with Plan XVII and an offensive interpretation of the German "Aufmarsch II" deployment plan by Helmuth von Moltke the Younger. The German concentration on the right (northern) flank, to wheel through Belgium and attack the French in the rear, was delayed by the movement of General Charles Lanrezac's Fifth Army towards the north-west to intercept them and the presence of the British Expeditionary Force (BEF) on his left flank. The Franco-British were driven back by the Germans, who were able to invade northern France. French and British rearguard actions delayed the German advance, allowing the French time to transfer their forces to the west to defend Paris, resulting in the First Battle of the Marne.
