Alfried Felix Alwyn Krupp von Bohlen und Halbach (13 August 1907 – 30 July 1967), often referred to as Alfried Krupp, was a German industrialist, a competitor in Olympic yacht races, and a member of the Krupp family, which has been prominent in German industry since the early 19th century. He was convicted after World War II of crimes against humanity for the genocidal manner in which he operated his factories (with the use of slave labor) and sentenced to twelve years in prison, subsequently commuted to three years with time served in 1951.
The family company, known formally as Friedrich Krupp AG Hoesch-Krupp, was a key supplier of weapons and materiel to the German Government and the Wehrmacht during World War II. In 1943, Krupp became sole proprietor of the company, following the Lex Krupp ("Krupp Law") decreed by Adolf Hitler. Krupp's wartime employment of slave labor resulted in the "Krupp Trial" of 1947–1948, following which he served three years in prison. At Krupp's behest, after his death in 1967, control of the Krupp company passed to the Alfried Krupp von Bohlen und Halbach Foundation, a philanthropic organisation.
Krupp's mother, Bertha Krupp, inherited the company in 1902 at the age of 16 when her father, Friedrich Alfred Krupp committed suicide after being exposed in the newspapers as a homosexual. In October 1906, Bertha married Alfried's father, Gustav von Bohlen und Halbach, a German diplomat and member of the nobility in a Lutheran ceremony, who subsequently added the Krupp name to his own by permission of Emperor Wilhelm II. Alfried was born almost a year later.
Alfried Krupp attended grammar school, after which he trained at the Krupp company workshops and studied metallurgy at technical universities in Munich, Berlin and Aachen. The company profited significantly from the German re-armament of the 1920s and 1930s. Gustav Krupp von Bohlen und Halbach, in spite of his initial opposition to the Nazi Party, made significant personal donations to it before the 1933 election, because he saw advantages for the company in the Nazis' militarism and their opposition to independent trade unions.
