Catherine E. Coulson began her professional association with director David Lynch when she worked as assistant director on Lynch's legendary feature debut Eraserhead (1977). This is when the two began discussing the idea of a woman who carried a log around with her. Coulson spent much of her career working behind-the-scenes before finally bringing the Log Lady to life on Lynch's cult TV series Twin Peaks (1990). The Log Lady was one of the most puzzling and emblematic of the show's characters, and she has ensured Coulson a permanent place in the hearts of cult TV fans.
