Hope Summers could portray a friendly neighbor or companion as she did for Frances Bavier's Aunt Bee character on many episodes of The Andy Griffith Show (1960) or a seemingly amiable Satanist in Rosemary's Baby (1968).

Born in Mattoon, Illinois, she developed an early interest in the theater. Graduating from Northwestern School of Speech in Evanston, Illinois, she subsequently taught speech and diction there. This, in turn, led to her the head position in the Speech Department at Bradley University in Peoria, Illinois, teaching students privately on the side as well. In the 1930s Hope began to focus on acting. She found work in community and stock theaters in Illinois and earned some notice for putting on one-woman shows such as "Backstage of Broadway." She made use of her vocal eloquence by building up her resumé on radio, performing in scores of dramatic shows, including "Authors' Playhouse," "First Night," "Ma Perkins", and "Step-Mother".
