Radio personality Jean Shepherd will be guest speaker at a College Hour program at 1 p.m. next Thursday at Union Junior College in the theatre of the Campus Center. Mr.. Shepherd, who has been described as a radio personality, philosopher, wit, egotist, intellectual and humorist, will visit the Union Junior College campus in celebration of King Levinsky Day. A committee from the Student Council is now seeking reasons why King Levinsky Day should be celebrated. They have yet to come up with an answer. Mr. Shepherd is heard every evening, Monday through Friday from 10:15 to 11 o'clock on WOR in programs of informal conversations, verbal essays and dramatic sketches. His topics range from comic books to cravats, baseball to babies, and kite flying to kissing. The College Hour programs are sponsored by the Day Session Student Council. N. Michael Lindenman, council president, said the public is invited to hear Mr. Shepherd's lecture. It was, Mr. Shepherd who coined the concept of the "Night People," maintaining they are far different from "Day People." He became interested in radio in his early teens and-won his ham license at 14. He had a fling at the dramatic end of radio with a stint as Billy Fairfield on ''Jack Armstrong." As a football star in high school, he was called upon to appear on a weekly radio program for students, doing sports commentaries and making football predictions. The Chicago station manager, impressed with his work, gave him the chance to do a regular program of his own. From these beginnings he got straight acting assignments on various radio adventure series of the day. After having served for three years in the Army Signal Corps, Mr. Shepherd returned to Chicago. While attending college there he enrolled in the distinguished Goodman Memorial Theatre. Summer stock roles and radio jobs kept him busy until he turned to radio full time after getting his B.S. degree in psychology in 1946. He originally started out at Indiana University, to major in engineering and after his Army stint of working with a radar unit, he switched to psychology and later earned his master's degree in psychology.
