Bertha Frederich née Heyn (1825 - May 10, 1882 Koblenz) was a German novelist. She used pseudonyms, including Golo Raimund.
She was born in 1825, in the Kingdom of Hanover. She married Eduard Frederich, editor of the Hannöverscher Courier, in which her first writings appeared. In order to conceal her identity, she used various pseudonyms—going so far as to have the true authorship of her novels ascribed to a fictitious personage, Georg Dannenberg. She wrote, in all, about 22 novels, nearly all of which have been republished.
