Introduced to science fiction by his high school chemistry teacher in 1947, he became active in fandom will serving in the Army Chemical Corps in the early 1950s, attending club meetings in Baltimore and Philadelphia. His first convention was TASFIC. The following year saw him living in Chicago and joining the University of Chicago Science Fiction Club, where he eventually was elected president, a position made permanent for him in 1963. As attendance and activity dropped off, he began hosting parties at his home at 1439 W. North Shore on the third Saturday of each month, which continued for twenty years. Eventually, the attendance changed from members of the University of Chicago club to members of the University of Illinois-Chicago Circle Campus and DePaul University Society of Science Fiction Freaks and Armchair Speculators. He was part of the Chicago: 1959 Worldcon bid.
An early (but not founding) partner in Advent:Publishers, joining the company in 1951, as the other partners left Chicago, Price eventually found himself in charge of the company and by 1965 was responsible for most of the tasks of the company.
