The Krupp Family's Krupp Armaments has always been the largest military enterprise in Germany.
Germany's first armored vehicles were products of Krupp Armaments.
As for Gustav Krupp, his last name was not actually Krupp, but Halbas.
His wife, Bertha Krupp, was the only daughter of the previous head of the Krupp Family, Friedrich Krupp.
After Friedrich Krupp passed away, Bertha Krupp could manage all the family enterprises, but at that time, Germans did not believe a woman could manage the vast Krupp Family's businesses well.
Thus, Emperor Wilhelm II personally chose a husband for the young Bertha, selecting Prussian diplomat Gustav von Bohlen und Halbach, and they married on October 15, 1906, with the emperor approving Gustav to bear the Krupp surname.
During World War I, Krupp Armaments provided a large number of weapons to the German military. After the war ended, Gustav Krupp was tried as a war criminal, but he did not serve any sentence!
