The street naming committee named the square after James Hurtle Fisher, South Australia's first Resident Commissioner, on 23 May 1837. In March 2003, as part of the
City of Adelaide's dual naming project, in association with the
University of Adelaide's Kaurna Dictionary Project, the square was assigned the name "Tangkaira", a word which means "fungus", after a prominent Kaurna person. Tangkaira (also known as Charlotte), who came from the
Clare district, was the wife of
Ityamai-itpina (aka "King Rodney"), a key negotiator with the new colonists. She provided what would become an important resource for reviving the Kaurna language in recent times, by writing one of the earliest examples of the written Kaurna language: a letter by school children to
Governor Gawler in 1841, pleading that he continue working as Governor. ==Description==
