The man who was known as the Cannon King started out in steel.
Alfred Krupp (1812 - 1887), whose father Friedrich (1787 - 1826) established the family's cast-steel factory in 1811, began manufacturing guns in 1856. Krupp supplied large weapons to so many nations that he became known as the Cannon King. Prussia's victory in the Franco-German War of 1870 - 1871 was largely the result of Krupps field guns. In 1933 when Hitler came to power, this family business began manufacturing a wide range of artillery.
Alfried Krupp (1907 - 1967), the greatgrandson of Alfred, supported the Nazis in power and accrued staggering wealth for the company an another Cannon King. The firm seized property in occupied countries and used slave labor in its factories. After the war, Alfred was imprisoned for twelve years and had to forfeit all his property. Granted amnesty in 1951, he restored the business to its former position by the early 1960s. On his death in 1967, however, the firm became a corporation and the Krupp family dynasty ended.
