John Gneisenau Neihardt (January 8, 1881 – November 3, 1973) was an American writer and poet, amateur historian and ethnographer.
Born at the end of the American settlement of the Plains, he became interested in the lives of those who had been a part of the European-American migration, as well as the Indigenous peoples whom they had displaced.
In 1901, Neihardt moved to Bancroft, Nebraska, on the edge of the Omaha Reservation, beginning a lifelong fascination with Indian cultures.
In the summer of 1930, as part of his research into the American Indian Ghost Dance movement, Neihardt contacted an Oglala holy man named Black Elk.
The Indiana University professor Raymond DeMallie, who has studied the Lakota by cultural and linguistic resources, published "The Sixth Grandfather" in 1985 including the original transcripts of the conversations with Black Elk, plus his own introduction, analysis and notes.
[2] The primary criticism made by DeMallie and similar scholars is that Neihardt, as the author and editor, may have exaggerated or altered some parts of the story to make it more accessible and marketable to the intended white audience of the 1930s, or because he did not fully understand the Lakota context.
