Heinz Kloss

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

He coined the terms "Abstandsprache" and "Ausbausprache" to try to describe the differences between what is commonly called a dialect and what is commonly called a language.

Kloss was also responsible for summing up previously publicly available statistical data on the North American Jewish population. One copy was found in Hitler's library. The book 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. However, the text of the book had already been available online from the Deutsche Nationale Bibliothek.

There is a Heinz Kloss fonds at Library and Archives Canada. The archival reference number is R11623. Provided by Wikipedia
