Wilhelm Heinrich Immanuel Bleek was a German linguist. His work included A Comparative Grammar of South African Languages and his great project jointly executed with Lucy Lloyd: The Bleek and Lloyd Archive of ǀxam and !kun texts. A short form of this eventually reached press with Specimens of Bushman Folklore, which Laurens van der Post drew on heavily.

Sir Laurens Jan van der Post, was a South African Afrikaner writer, farmer, soldier, educator, journalist, humanitarian, philosopher, explorer and conservationist. He was noted for his interest in Jungianism and the Kalahari Bushmen, his experiences during World War II, as well as his relationships with notable figures such as the future King Charles III and British Prime Minister Margaret Thatcher. After his death, there was controversy over claims that he had exaggerated many aspects of his life, as well as his sexual abuse and impregnation of a 14-year-old girl.
