active 1922-1937 Peter Nielsen

Very little biographical information about this author could be confirmed from reliable public sources. Project Gutenberg lists him simply as Peter Nielsen, active 1922–1937, which suggests those are the years in which he is known to have been publishing or otherwise active.

The work most clearly associated with him is The Black Man's Place in South Africa, published in 1922. Archive and library records show the book was issued in Cape Town by Juta & Co., and it has remained accessible through public-domain and library collections.

Because so few trustworthy details about his life were available, it is safest to describe him as an obscure early-20th-century author whose surviving reputation rests largely on that book and its discussion of South African social conditions of the time.
