Heinz Kloss (30 October 1904, in Halle, Saxony-Anhalt – 13 June 1987) was a German linguist and internationally recognised authority on linguistic minorities.^[1]

He coined the terms "Abstandsprache" and "Ausbausprache"^[2] as a contribution to disentangle the incongruent use of the terms dialect and language, which cannot be solved on linguistic grounds alone without a social component.

^[3]

Kloss had various roles in research institutions in the Third Reich and made career steps during that time.^[4] He was, for instance, responsible for summing up publicly available statistical data on the North American Jewish population. One copy of the book was found in Hitler's library,^[5][6] which was entitled Statistics, Media, and Organizations of Jewry in the United States and Canada. Hitler's personal copy of the book was obtained by Library and Archives Canada in 2018 and was restored, digitized and made available to the public in 2019.^[7] The text of the book itself, not Hitler's copy, is available online from the Deutsche Nationale Bibliothek.^[8]

There is a Heinz Kloss fonds at Library and Archives Canada.^[9] The archival reference number is R11623.
