Actor William Conrad had a long career in radio, movies and television. I probably first heard of him when he narrated episodes of Rocky and Bullwinkle. Later when I listened to old radio shows on KSFO, I heard him in Gunsmoke, where he played the original Marshall Matt Dillon, and in anthology shows like Suspense and Escape. Later I saw him in films noir like The Killers. I don't think I watched any of his television shows, even though Cannon was set in San Francisco. I enjoyed the Mad Magazine satire, "Cannonball."
