Johan Thorsten Sellin (1896-1994) was a sociologist and internationally-recognized criminology expert. The Johan Thorsten Sellin Papers include correspondence; biographical materials; drafts of writings; notes; clippings about Sellin’s work; minutes; reprints of criminology articles; memorabilia; and some photographs. The material is largely professional, not personal, and documents Sellin’s research as a penologist and his career as a teacher of sociology and criminology, as well as his works in Swedish-American causes.
