According to the San Diego Zoo history page, Tasmanian Devils first arrived at the San Diego Zoo in 1956.
According to the Ft. Wayne Indiana Zoo history page, their male became the last Tasmanian Devil living outside of Australia in 2003 when the remaining US Zoo devils died of old age. I remember the San Diego male died before the female, so the male may have died in 2002 or early 2003 and the female in 2003.
Coolah, a male, the last Tasmanian devil outside of Australie died in May 2004 at Ft. Wayne zoo
