Greenberg, a television screenwriter who was active in the 1950s and 60s. In addition to Dr. Baxter, it starred Wilder Penfield and Hadley Cantrell, with actor Karl Swenson playing the role of a cameraman (the program was set on a soundstage in a mock "behind-the-scenes" format). Chuck Jones directed the animation, which was designed by Maurice Noble. In 1966, Jones won an Academy Award for Best Animated Short Film for directing The Dot and the Line: A Romance in Lower Mathematics
