Antoine Andrei Maximoff (b. 19 January 1953) was a pure-blood wizarding author from New Zealand. Youngest child of the late Django and Tania Maximoff (née Ceausescu), Antoine is of Romanian descent, but was born and raised in New Zealand with his elder brother Emilian. His father was an Auror and actually fought for Grindelwald's army during his invasion of Europe, though he switched sides and became a spy. Antoine attended the Oceania School of Magic from 1964 until 1972. His father became the Minister for Magic of Romania in 1969 but was assassinated in 1973. The death of his father was followed by his mother only four months later, which severely depressed both Antoine and his brother.
After graduating from Oceania, Antoine became a popular author, specializing in historical fiction. He moved to Norocstat, a wizarding town in Romania, in the early seventies and married a local woman named Crystalia Antonescu. With her he had a son, Mateo, however Crystalia was afflicted with a disease that slowly ate away at her magic and died in mid-1980. Antoine eventually remarried, taking Carmela De Santa (née Scicolone) as his second wife. He became the stepfather of her two sons, Pietro and Marco, and had an additional two children; twin girls Wanda and Marya Maximoff. Because of his new marriage, Antoine's relationship with his son deteriorated, and he left home at the age of fourteen after an argument stemming from Mateo's use of Dark Magic. Mateo eventually returned home and Antoine took him back into the family with open arms.
