King Levinsky Day will be celebrated today by the students at Union College, as radio personality Jean Shepherd makes his annual visit. His visit will be sponsored by Alpa Phi Omega Fraternity and "The Paper," daily student newspaper at Union College. Mr. Shepherd will speak at 1 p.m. in the theatre of the Campus Center. The program will be open to the public and tickets will be available at the door. This will be the seventh consecutive year Mr. Shepherd has visited the Union Junior College campus to observe King Levinsky Day and to pan Mary Martin. King Levinsky, for the uninitiated and those not up on their important American holidays, was a gladiator of the first order until he ran into (really away from) a youngster known as the Brown Bomber, alias Joe Louis. Our hero (King Levinsky, that is) was knocked from his pedestal and was never heard from again." Mr.. Shepherd, who has been described as a radio personality, philosopher, wit, egotist, intellectual and humorist, 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. 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.
