1964); reporter Ned Leeds in No. 18 (Nov. 1964); and the Scorpion in No. 20 (Jan. 1965). The Molten Man was introduced in No. 28 (Sept. 1965) which also featured Parker's graduation from high school. Peter began attending Empire State University in No. 31 (Dec. 1965), which featured the first appearances of friends and classmates Gwen Stacy and Harry Osborn. Harry's father, Norman Osborn first appeared in No. 23 (April 1965) as a member of Jameson's country club but was not named nor revealed as Harry's father until No. 37 (June 1966).
