Although it was never addressed,
You'd have to have the lamp-like eyes of Filch's cat Mrs Norris to spot this one: Newt Scamander actually appears in Harry Potter and the Prisoner of Azkaban, and not just as a name on a textbook.
As depicted in Harry Potter and the Prisoner of Azkaban, Newt Scamander visits Hogwarts in 1993 or 1994 for some unknown reason, thus appearing on the Marauder's Map. Newt writes A Children's Anthology of Monsters, an edition for younger readers. As of 2017, Newt Scamander is still "alive and well".
Newt Scamandar is just a few years younger than Albus Dumbledore. He is not a contemporary of Harry and his friends. In the books he is mentioned only as the author of a textbook, and he never appears as a guest lecturer, let alone a teacher. So there is no need for him to be in any of the Harry Potter movies.
Scamander ended up at Hogwarts after his travels across five continents to study, collect, and protect fantastic beasts. So it's altogether possible that a younger Hagrid met a middle-aged Scamander at Hogwarts in the '40s.
Newt believed that magical creatures were not dangerous if treated with respect, and Buckbeak only attacked Malfoy when he disrespected him. Due to this, Newt would have gladly traveled to Hogwarts to defend Buckbeak and try to prevent his execution, causing him to appear on the Marauder's Map.
No, Newt Scamander is not Hagrid's father.
Since the map shows the location of every single person at Hogwarts at the given time, that means Newt Scamander was somewhere on the grounds at the school during that time. So, even though he wasn't featured on screen.
He's Luna Lovegood's grandfather-in-law
Newt's full name is Newton Artemis Fido Scamander.
“The reason he loves Newt is that Newt loves beasts and I think he thinks he's a beast.” The actor continued: “I think he thinks he's dark, that he's seen and done things that he wishes he hadn't and he's constantly pulling himself back on the right moral side.”
Meanwhile, Newt was a Hufflepuff, who are known to be hard workers, loyal and dedicated. He rarely grew angry in Fantastic Beasts and Where to Find Them, but instead accepted his fate when he was arrested by Tina, and remained cool-headed after being given the death penalty (and fought his way out, of course).
Fantastic Beasts: The Secrets of Dumbledore confirmed that Credence Barebone/Aurelius Dumbledore (Ezra Miller) is the new Snape (Alan Rickman) through a very familiar line delivered by Aberforth Dumbledore (Richard Coyle).
Speaking of his most recent release, Fantastic Beasts: The Secrets of Dumbledore, in which he played Gellert Grindelwald, Mikkelsen admitted he'd had concerns about replacing Johnny Depp, who withdrew from the franchise due to his much-publicized court case with ex-wife Amber Heard.
He hunches, seems skittish around people, and often avoids eye contact. All of this anti-social behavior falls in line with Newt's introverted personality, but one Reddit user has a different theory. Newt acts this way because he approaches people the same way he approaches animals.
The writer of the Fantastic Beasts series, J.K. Rowling has never publicly stated that Newt has autism or was written to be autistic.
Newton Artemis Fido "Newt" Scamander is a half-blood or pure blood wizard who is a framed magizoologist and the main protagonist of the Fantastic Beasts and Where to Find Them franchise.

We are sure that Hufflepuffs the world over rejoiced in jubilation when Newt Scamander opened his suitcase to reveal a cheerful, yellow Hufflepuff scarf. Here's how the hero of Fantastic Beasts perfectly represents his Hogwarts house.
Tom Riddle, Lord Voldemort was a wizard and the Dark Lord of the Death Eaters.
It's not mentioned that they knew each other well, but it is mentioned that they spoke at least once. Dumbledore also doesn't say he taught Newt, so nothing written there even hints at them knowing each other in any way other than Dumbledore knowing that Newt wrote a very good textbook.
No, Hagrid is not in Fantastic Beasts and Where to Find Them. He would not have been born yet. Fantastic Beasts and Where to Find Them serves as a prequel for the Harry Potter series, where Hagrid is a recurring character.
Funnily enough, the most famous Lestrange is one only by marriage, and despite really adorable Instagram photos that make us wish it so, there is no blood relation between Leta and Bellatrix whatsoever. At most, Leta and Rodolphus Lestrange (Bellatrix's husband) are very distant cousins.
Throughout the film, Leta hints that she has a horrible, dark past involving her dead brother. Eventually, it's revealed that when she was a child living in London, her father sent her and her brother away to America. The ship they were on sank and her infant brother perished – and that ship, was the Titanic.
Therefore, it is unlikely that the Qilin would bow to Newt, as it would be out of character for the creature and would not fit within its code of conduct. In addition, it may not have been aware of Newt's standing or significance, which would further explain why it did not bow to him.
