Pen names for movie critics at newspapers were pretty common back then, especially when could they just assign a reporter needing a story to go to the theater and see the show. The fact that the Tribune kept it up until 1967 meant that Gene Siskel was only one away from being "Mae Tinee" (his predecessor, Clifford Terry, refused the pen name). At the Sun-Times, the movie critic pen name was "Doris Arden"--and Roger Ebert flat-out refused to use the name, at about the same time the Trib put "Tinee" to pasture.
