Ingrid was described as a genius. After years of experimenting on different inks from different creatures, she founded Ink Inc. with her business partner, Colonel Colophon. Her company fetched ink from the octopi, which was famously dark and made her and her family very rich.
At some point, she had a son, Ignatius. After Colophon was injured in an explosion, Ingrid left the company to her son when she died.
Her granddaughter, Cleo, presumably inherited her scientific skills from her.
- Her first name may be a reference to noir actress Ingrid Bergman.
- Her middle name, "Nummet", is a word that means "a light meal, esp. one taken in the middle of the day."
- Her initials spell out INK.
