Problem:Context_1 : The Panzerkampfwagen III, commonly known as the Panzer III, was a medium tank developed in the 1930s by Germany, and was used extensively in World War II. The official German ordnance designation was Sd.Kfz. 141. It was intended to fight other armoured fighting vehicles and serve alongside and support the Panzer IV; however, as the Germans faced the formidable T-34, more powerful anti-tank guns were needed, and since the Panzer IV had more development potential, it was redesigned to mount the long-barrelled 7.5 cm KwK 40 gun. The Panzer III effectively became obsolete in the anti-tank role and was supplanted by the Panzer IV. From 1942, the last version of Panzer III mounted the 7.5 cm KwK 37 L/24, better suited for infantry support. Production of the Panzer III ended in 1943. However, the Panzer III's capable chassis provided hulls for the Sturmgeschütz III assault gun until the end of the war. Context_2 : The 3.7 cm KwK 36 L/45 "(3.7 cm Kampfwagenkanone 36 L/45)" was a German 3.7 cm cannon used primarily as the main armament of earlier variants of the German SdKfz.141 Panzerkampfwagen III medium tank. It was used during the Second World War. Context_3 : The 8.8 cm KwK 43 L/71 (Kampfwagenkanone —"fighting vehicle cannon") was an 88 mm 71 calibre tank gun designed by Krupp and used by the German Wehrmacht during the Second World War. It was mounted as the primary armament on the Panzerkampfwagen VI Ausf. B "Tiger II" and the 8.8 cm PaK 43, an anti-tank gun, was very similar in design and use albeit not mounted on tanks but rather on tank destroyers or deployed on the field. Context_4 : The Krupp family (see pronunciation), a prominent 400-year-old German dynasty from Essen, have become famous for their production of steel, artillery, ammunition, and other armaments. The family business, known as Friedrich Krupp AG, was the largest company in Europe at the beginning of the 20th century. It was important to weapons development and production in both world wars. One of the most powerful dynasties in European history, for 400 years Krupp flourished as the premier weapons manufacturer for Germany. From the Thirty Years' War until the end of the Second World War, they produced everything from battleships, U-boats, tanks, howitzers, guns, utilities, and hundreds of other commodities. Context_5 : The 8.8 cm KwK 36 L/56 (German: "8,8 cm Kampfwagenkanone 36 L/56" ) was an 88 mm tank gun used by the German Heer during World War II. This was the primary armament of the PzKpfw VI Tiger I tank. It was developed and built by Krupp. Context_6 : The Tiger I    was a German heavy tank of World War II deployed from 1942 in Africa and Europe usually in independent heavy tank battalions. Its final designation was "Panzerkampfwagen VI Tiger Ausf. E" often shortened to "Tiger". The Tiger I gave the Wehrmacht its first armoured fighting vehicle that mounted the 8.8 cm KwK 36 gun (not to be confused with the 8.8 cm Flak 36). 1,347 were built between August 1942 and August 1944. After August 1944, production of the Tiger I was phased out in favour of the Tiger II. Context_7 : The 5 cm KwK 39 L/60 "(5 cm Kampfwagenkanone 39 L/60)" was a German 50 mm calibre gun used during the Second World War, primarily as the main armament of later models of the German Panzerkampfwagen III tank from 1941 onwards. It was produced when the well-armoured T-34 and KV-1 tanks were encountered in ever increasing numbers on the Eastern Front, although it was only partially successful in its role. It was later superseded by the 7.5 cm KwK 40 L/43. Context_8 : The Jagdpanther (German: "hunting panther"), SdKfz 173, was a tank destroyer built by Nazi Germany during World War II based on the chassis of the Panther tank. It entered service in 1944 during the later stages of the war on the Eastern and Western Fronts. The "Jagdpanther" combined the 8.8 cm KwK 43 cannon of the Tiger II and the armor and suspension of the Panther chassis, although it suffered from the general poor state of German ordnance production, maintenance and training in the later part of the war, which resulted in small production numbers, shortage of spare parts and poor crew readiness. Context_9 : The 8.8 cm Flak 16 was a German 88 mm anti-aircraft artillery gun from World War I, the forerunner of the later 88 mm guns of World War II. Its contemporary name was the 8.8 cm K.Zugflak L/45. Context_10 : The Pak 43 ("Panzerabwehrkanone 43" and "Panzerjägerkanone 43") was a German 88 mm anti-tank gun developed by Krupp in competition with the Rheinmetall 8.8 cm Flak 41 anti-aircraft gun and used during World War II. The Pak 43 was the most powerful anti-tank gun of the Wehrmacht to see service in significant numbers, also serving in modified form as the 8.8 cm KwK 43 main gun on the Tiger II tank, to the open-top Nashorn, and fully enclosed, casemate-hulled Elefant and Jagdpanther tank destroyers. fact_1 :  It was developed and built by Krupp. fact_2 : The Krupp family (see pronunciation), a prominent 400-year-old German dynasty from Essen, have become famous for their production of steel, artillery, ammunition, and other armaments. Answer: Essen
Solution:
What German city was the family that developed and built the 8.8 cm KwK 36 L56 from?
