One innovation developed by this organization was only approved for a patent after a long struggle  with the Baron von Roon, who opposed that innovation's use. Many innovations developed by this  organization were tested at Meppen, where one head of this organization organized the Volkerschiessen  event. This organization became involved in the business for which it is best known in the early 19th  century when its head Friedrich founded the Gusstahlfabrik, and that involvement continued under  Friedrich's son Alfred, who prospered due to his contacts with Wilhelm I. This organization was  responsible for the creation of a mostly-useless object with a meter-wide muzzle cal ed the Big Gustav,  though perhaps its most famous creation was the 42 centimeter caliber mortar deployed during the  siege of Liege and named Big Bertha after its baroness head. For 10 points, identify this company which  provided much of the armaments for Prussia, the First Reich, and Hitler's regime, which takes its name  from the family that founded it.
