Austin Stevens was born in Pretoria, South Africa and became interested in snakes at the age of 12. By the time he finished school, his reptile collection included some of the most exotic and venomous species in the world.

His mother lost a lung in a car accident as a girl, was often ill, and died when Stevens was in his 30s; his father owned a small typewriter repair business. He traces his adventurous streak back to his grandfather from Bristol, England—also named Austin James Stevens—part founder of the AJS Motorbike Corporation, but later took the boat to Africa
