Before the advent of computers, students working for the Iowa State Daily–and, indeed, anyone working for a newspaper or printing press–had to set type by hand. In the photograph below, we see two men checking columns of type that have been set for printing.
The back of the photograph informs us that the man on the left is Leo Mores. Mores was a graduate of then-Iowa State College (1938) who shortly after graduating purchased the Harlan (Iowa) Tribune, and in 1945 also purchased its competing paper, the News-Advertiser.
This photograph is from the Department of Journalism and Mass Communication (RS 13/13). The second man is likely a student, who may have been working with Mores at one of his Harlan newspapers.
