Behind the Scenes
First Appearance:
  "Tour de Ferb"

Gertrude Zupermühltienatör was Heinz Doofenshmirtz's maternal grandmother. Heinz mentioned to Perry the Platypus that her maiden name was a sign to buy a Super Multi-Inator he found on the internet ("Tour de Ferb").

Background Information

  • Her last name includes letters with umlauts (ö), which change the pronunciation of the word based on the consonants. With this in mind, the ö would be pronounced as 'ou' and the ü would be pronounced as a 'ue'.
  • Her last name includes the letter "ö" which is used in European countries including Germany, the country closest in relation to Drusselstein, where the Doofenshmirtz family came from. In fact, the name "Zupermühltienatör" doesn't exactly sound like Super Multi-Inator in German.
  • She is called Frau Gertrude Zupermühltienatör, which is German for Ms./Mrs. Gertrude Zupermühltienatör (The German title "Frau" is used for married and unmarried women).
  • She has the same name (Gertrude) as Heinz Doofenshmirtz's cousin, which is also the middle name of Candace Gertrude Flynn. ("Attack of the 50 Foot Sister", "Fireside Girl Jamboree")
