The 1937 incorporation documents of the Pioneer Fund list two purposes. The first, modeled on the Nazi Lebensborn breeding program, was aimed at encouraging the propagation of those "descended predominantly from white persons who settled in the original thirteen states prior to the adoption of the Constitution of the United States and/or from related stocks, or to classes of children, the majority of whom are deemed to be so descended". Its second purpose was to support academic research and the "dissemination of information, into the 'problem of heredity and eugenics and "the problems of race betterment". The Pioneer Fund argues the "race betterment" has always referred to the "human race" referred to earlier in the sentence, and critics argue it referred to racial groups. The document was amended in 1985 and the phrase changed to "human race betterment."
