OPINION| The late Dr. Marshall Saper was a radio psychologist and host of a call-in show in Kansas City in the 1980s and early 1990s. Dr. Saper hosted the show for about 11 years, beginning on KCMO in 1980, then on rival KMBZ-AM, and back to KCMO in 1983. At KCMO, he hosted a top-rated three-hour call-in show on weekdays. Earlier in his career, Dr. Saper provided psychological services to the Kansas City, Missouri, police department and taught at the University of Missouri-Kansas City Medical School. He wrote three books, the first of which, “Talking to Myself,” was a bestseller. He also wrote a biweekly column for the Squire, a suburban weekly, for eight years. Unfortunately, he took his own life in 1991 at age 52. Some fading on front of book, the red has lightened Copyright 1986 Ships in 1 business day
