Karl Friedrich Otto Ruß (January 14, 1833, Baldenburg – September 29, 1899, Berlin) was a Prussian pharmacist, aviculturist, author of bird-keeping books, and the founding editor of the world's first bird-fancier magazine Die Gefiederte Welt. Along with Bruno Dürigen, he also founded the magazine Isis in 1876.[1] He sometimes wrote under the pseudonym "Berthold Schwarz". He was among the few who managed to breed the now extinct Carolina parakeets in captivity.
