1913 Dr. Eugen Fischer's book Die Rehobother Bastards und das Bastardisierungsproblem beim Menschen (The Bastards of Rehoboth and the problem of miscegenation in Man) is published. In it he writes about the people of mixed blood in German South-West Africa: "We should provide them with the minimum amount of protection which they require, for survival as a race inferior to ourselves, and we should do this only as long as they are useful to us. After this, free competition should prevail and, in my opinion, this will lead to their decline and destruction." (Science)
