She was gifted by the Sultan of Johore in exchange for some Australian animals, and has been in the care of the Perth Zoo since 1968.
The world's oldest Sumatran orangutan, a prolific mother who is estimated to have given birth to 10 per cent of the global population of the species in captivity, has died at the age of 62.
Puan, described as the "grand old lady" of Perth Zoo, was euthanised on Monday due to age-related complications.
"It's always hard to make that decision for any animal, but it was the right decision and a respectful end for an old lady who demanded respect throughout her life", primate supervisor Holly Thompson said.
Female orangutans rarely live past the age of 50, and in 2016, she was recognized by the Guinness Book of Records as the oldest verified living Sumatran orangutan in the world.
Puan, meaning "lady" in Indonesian, left behind an "incredible legacy" of 54 descendants including 11 children and was a celebrated matriarch who helped save her species, according to a statement from Perth Zoo.
Its descendants now make up almost 10 per cent of the total population of the species in zoos around the world.
"You always knew where you stood with Puan, and she would actually stamp her foot if she was dissatisfied with something you did". She really has seen it all, from the jungles of the wild to the old exhibits here at Perth, to our now world-class exhibits.
"Over the years Puan's eyelashes had greyed, her movement had slowed down and her mind had started to wander". She was in a zoo environment, but to the end she always maintained her independence.
She added that her legacy as a wild-born orangutan will be carried on by her great-grandson Nyaru who is now living in the jungles of Sumatra.
She leaves two daughters at the zoo, along with four grandchildren and a great-grandson.
Behind the collapse in numbers is an increase in industrial agriculture, large-scale cattle ranching, logging, oil and gas drilling, mining, dam building and road construction.
