His Wikipedia entry has some background on his life
John Howard "Pondoro" Taylor (1904–1969) was a big-game hunter and ivory poacher of Irish descent. Born in Dublin as the son of a surgeon he developed an urge to go to Africa and become a professional hunter. Taylor mainly hunted for his own account and had little interest in guiding clients. His parents paid for his passage to Cape Town. In Africa he experimented extensively with different types of rifles and calibers which made him an expert in big game rifles. He is credited with developing the Taylor KO Factor, and authored several books. John Taylor died in 1969 in London.
Having hunted over thirty years on the African continent, Taylor killed over 1,000 elephants, many of these illegally. Taylor's personal life in later years was one of misfortune. As an alleged homosexual, Taylor was persecuted in Africa in his latter years there and was eventually forced by local authorities to leave Africa due to his continued poaching offences. Taking into account his vast experience as a hunter, as well as his expertise with rifles, Taylor should have had no trouble finding a well paying job as a representative of one of the high end gunmakers in London. However, whispers alluding to Taylor's homosexual past in Africa followed him to England, and he found little work available. Taylor's last years were spent in poverty.
He was expelled from school because of violent behaviour, and had to leave Ireland after joinung the ADRIC, then apparently further foraies into politics. Sinn Fein are believed to have promted him to escape Ireland. He and his brother fled to Canada, where again he was expelled for being involved in smuggling . Having read a Rider Haggard book earlier, he decided on a whim to go to Africa. On arriving in Buluwayo in the then Southern Rhodesia, he bought a BSA .303 Sporter rifle and headed into the bush. He poached literally thousands of elephants and other game
Books by him and books about him are entertaining. It is difficult to know how much is true and how much is the myth. But it is true that he fell on hard times on his return to UK, and died in poverty.
