Theseus Scamander? The war hero?
-- Momolu Wotorson (WFT)
Theseus Scamander was the older brother of Newt Scamander and a well-known hero of World War One.
- When Newt Scamander appeared before MACUSA in 1926 after creatures escaped from his case, the British Envoy recognized his last name, as did a witch named Momolu Wotorson, because of his famous elder brother Theseus (WFT).
Brother to magizoologist Newt Scamander.
The magical world on both sides of the Atlantic considered him a hero of World War One.
Actor Colin Farrell who played Percival Graves revealed in an Interview with Snitchseeker that his character was acquainted with Newt through his war-hero brother. Farrell said he was told that Theseus was a "very powerful and commanding British Auror." The text of the script, however, just calls him a war hero, not an Auror. Another possible clue to this is a letter designed by MinaLima for the first Fantastic Beasts movie in which Theseus writes to Newt that he has been chosen by the Ministry to help hunt down Grindelwald, but it does not specifically label him an Auror.
