Dubbed Australia's First Lady, Dame Edna is the invention of Barry Humphries, a successful character actor in Europe and Australia as well as an esteemed landscape painter.

Humphries was given the Order of Australia in 1982 and was endowed with an Honorary Doctorate of Griffith University in Australia in 1994. The Dame found success on Broadway during the 2000 season with her Tony Award-winning show, Dame Edna: The Royal Tour.
