Karl Kristian Vilhelm Steincke (25 August 1880 – 8 August 1963), was a Danish politician from the Social Democratic Party.
[1] He has been cited as the chief architect of the Danish welfare state with the Social Reform Acts of the early 1930s, including the Kanslergade Agreement.
[2] Steincke is especially known for his book The Future's Social Welfare (Danish: Fremtidens forsørgelsesvæsen) from 1920 in which he foretells: "We treat the inferior individual with all care and love, but forbid him, in return, only to reproduce himself."
His book was the basis of the Danish laws about Eugenics, the sterilization and castration of unwanted elements.
Steincke regarded the prevention of "inferior individuals" reproducing as important for society, as for the children of the "inferior individuals".
