Portrayed by Tom Knight
Mr Granger represents the ordinary Muggle world that exists parallel to the wizarding community, serving as a dedicated dentist who finds himself thrust into extraordinary circumstances through his daughter’s magical abilities. As Hermione’s father, he demonstrates remarkable adaptability and support when confronted with the reality that his child possesses powers he cannot fully comprehend, yet never wavers in his love and pride for her achievements.
His professional background in dentistry occasionally surfaces in humorous moments, particularly when he encounters the wizarding world’s rather cavalier attitude towards dental hygiene. Despite being entirely non-magical, he shows genuine interest in Hermione’s education at Hogwarts and maintains an open mind about the strange new world she inhabits. His wife shares his supportive approach, and together they create a stable, loving home environment that grounds Hermione throughout her adventures.
The family’s Muggle status becomes a source of danger during the Second Wizarding War, when Hermione makes the heart-wrenching decision to modify her parents’ memories and send them to safety in Australia. This sacrifice underscores the genuine threat that Voldemort’s regime posed to Muggle-born witches and wizards and their families.
Through his limited but meaningful appearances in the series, Mr Granger embodies the best qualities of the non-magical world: rationality, dedication to helping others through his medical profession, and unconditional parental love that transcends the boundaries between magical and Muggle society.
