Behind the ScenesEdit
Originally Doris was played by Barbara Pepper who early in her career was a stunning actress who worked in several forms of media. As she grew older, she gained considerable weight and began playing motherly or grumpy elderly roles similar to Doris. Despite a long career, she is best remembered for her role as Doris Ziffel. Barbara eventually left the show due to heart problems and was replaced by Fran Ryan who took over the role of Doris for the remainder of the series.
- During her early appearances on Petticoat Junction, she was called Ruth Ziffel, or "Ruthie" by her husband.
