American journalist Franz Lidz gave his two daughters the unusual names Gogo and Daisy Daisy, nickname “Didi.”
The names were inspired by the two male protagonists in Samuel Beckett’s Waiting for Godot: “Didi,” or Vladimir, and “Gogo,” or Estragon. (Estragon is the French word for the herb tarragon.)
