“The Great Pink Scare” recalls the 1960 arrests of three gay Smith College faculty members in Northampton, Mass. The instructors were among a group detained by police during a pornography investigation that focused on gay men. Included: comments from historians Barry Werth and Martin Duberman, and detainees Ned Spofford and Joel Dorius. “The house of cards I had built fell and smashed,” recalls Dorius, who died in 2006. “I had no job, no profession, nor any possibility of a return to one.”
