The time-traveling English teacher in Stephen King's 11/22/63 is Jake Epping.
Jake Epping is a high-school English teacher from Maine who learns about a portal leading to September 9, 1958. He is asked to use it to prevent the assassination of President John F. Kennedy on November 22, 1963. Jake adopts the identity George Amberson while living in the past.
King published 11/22/63 in 2011. The novel combines historical fiction, romance, suspense, and speculative time travel. Its central premise asks whether changing one event can improve history or instead create unexpected consequences.
Jake’s journey is not simply a trip to Dallas. He spends years in the past, develops relationships, teaches, and investigates Lee Harvey Oswald. The title uses the American date format for Kennedy’s assassination, a detail that can be confusing for international readers.
