== Personality ==
Erwin's father appeared to be highly intelligent, considering how he theorized about the Walls. He also cared deeply for his son's future, so much that he did not reveal his "dangerous" theory in his history class for his sake and the students', but later told Erwin.
== History ==
In Erwin's youth, Erwin's father was a teacher in their hometown. One day he was teaching history when a young, bright-eyed Erwin Smith asked him a question. He vaguely avoided it, ending class soon after. When they made their way home, he sat Erwin down and gave him an honest answer to his question based on what he believed. He mentioned that the history books, distributed by the government, were full of mysteries and contradictions. He believed that it was near impossible for humanity not to have passed down an oral history. Instead, the only way to ensure that humanity forgot about the history before the Walls would be to alter their memory in some way.
Due to Erwin's naivety, the Military Police caught wind of Erwin's father's theory. He was then secretly detained and tortured for what he knew. His body was then dumped in a far-off town, made to look like an accident.
