William Hurle Liddle (2 December 1888 – 8 September 1959) was a pastoralist who established Angas Downs Station (now Angus Downs Indigenous Protected Area), in Central Australia, taking up the first pastoral lease in 1929.
This is where he met, and married, Mary Earwaker the daughter of the blacksmith and a local Arrernte woman, in 1912.
Finlayson stayed with Liddle at Angas Downs and, although it was his primary purpose of his expedition to study mammals he took many photographs and recordings of Aboriginal people here.
This attracted the attention of the authorities and many of these children were taken to become members of the Stolen Generations.
The brothers, and their Aboriginal descendants, ran sheep and then cattle until the 1990s when, following financial struggles, they sold to the Imanpa Development Association Inc. and it became the Angas Downs Indigenous Protected Area.
