Overview
Grandmama is a fictional character in the Addams Family television and film series. First appearing in the works of cartoonist Charles Addams, she is a supporting character in the film, television, and stage adaptations.
Character background
Grandmama Addams is an aged witch who concocts potions and spells, and dabbles in fortune telling and knife throwing. She is the grandmother of the Addams children, Pugsley and Wednesday, although her relationship to the other family members is less consistent. Grandmama first appeared along with the then-unnamed Addams family in Charles Addams' original cartoons published in The New Yorker, in which she was regularly illustrated with shoulder-length frizzy hair and a fringed shawl. Addams described Grandmama in a 1963 character synopsis as "a disrespectful old hag" and "foolishly good-natured ... a weak character [who] is easily led."
Grandmama and Granny Frump
In Charles Addams' original The New Yorker cartoon strips, the character was referred to as Grandma Frump, therefore making her Morticia's mother.
For the original television series, her relationship to the family is retconned and she becomes Gomez's mother with a different Granny Frump remaining as Morticia and her sister Ophelia's mother. Granny Frump was also given a first name, which was [H/E]ster (and is, probably, Fester's sister). These versions of the characters were also used in the Halloween with the New Addams Family, TV movie.
