Frank Darby, who claimed to have been a keeper at Hobart Zoo, suggested Benjamin as having been the animal's pet name in a newspaper article of May 1968. No documentation exists to suggest that it ever had a pet name, and Alison Reid ("de facto" curator at the zoo) and Michael Sharland (publicist for the zoo) denied that Frank Darby had ever worked at the zoo or that the name Benjamin was ever used for the animal. Darby also appears to be the source for the claim that the last thylacine was a male. Robert Paddle was unable to uncover any records of any Frank Darby having been employed by Beaumaris/Hobart Zoo during the time that Reid or her father was in charge and noted several inconsistencies in the story Darby told during his interview in 1968.
