It was Himmler who in 1937 had introduced the concept of Lebensborn (‘Source of Life’) homes – institutions where SS officers could procreate outside marriage with selected Aryan women, in order to produce a constant supply of perfect Aryan children. In 1940 he passed a procreation order urging German soldiers to procreate outside marriage in order to produce as many children as possible, to resupply the gene pool. This need not be done secretly, he proclaimed.
