Siegfried Emanuel van Praag (8 August 1899 in Amsterdam – 16 March 2002 in Brussels), was a prolific Dutch writer of more than 60 books.

In the same year that Van Praag published his first novel De Weegschaal, he also married Hilda Sanders, a journalist.

Also, his wife's profession may have introduced him to radio broadcasting, an occupation which van Praag held during various phases of his life.

The rise of Nazism may have prompted a move to Brussels in 1936, and was definitely the reason why van Praag and his family left the continent for England in 1940.

But unlike so many other artists who were exiled to England or The New World he did return to Europe after the war, settling in the Netherlands once more.
