Haagner was born in Hankey near Humansdorp where his father, Sigmund, an accountant at the explosives factory in Modderfontein, taught him at home. Young Haagner then worked alongside his father in the accounts department but found natural history of greater interest. At the age of 19, he published a note on the Cape Monitor followed by several papers on the birds of Modderfontein in the Ibis around 1901–1902. He was one of the founding members of the South African Ornithologists' Union begun in Johannesburg on 8 April 1904, an organization that amalgamated with the Transvaal Biological Society in 1916 to form the South African Biological Society. Haagner worked in the Transvaal Museum from 1906 collecting grass species among other specimens and becoming an assistant in ornithology from 1908 to J.W.B. Gunning. Along with Gunning he began to assemble a collection of birds from the region. Haagner left the museum in 1911, was succeeded by Austin Roberts, and became director of the Pretoria Zoological Gardens. During his directorship, animals were transferred to zoos in Europe and the United States through dealers in wild animals, leading to accusations that he was involved in their trade. His argument was that he was promoting the continued survival of endangered species, by ensuring that breeding pairs were protected within zoos worldwide. He then worked at a farm near Beira, Mozambique and returned to South Africa somewhere in the 1940s and settled in Pietermartizburg, working as an accountant.
