Eddie Munson was born sometime between 1965 and 1968. His father was Al Munson, a man known for hatching dubious schemes. At some point, Al became absent from Eddie's life, and Eddie became the ward of his paternal uncle, Wayne Munson. The two lived at Wayne's trailer in Hawkins' Forest Hills Trailer Park. During the late 1970s, Eddie attended Hawkins Middle School. While attending Hawkins High, Eddie leads the school's Dungeons & Dragons club, the Hellfire Club.
