Catherine E. Coulson, 71, a classically trained actress who won fans on television as the enigmatic Log Lady in the cult classic series "Twin Peaks," died Monday at her home in Ashland, Ore.
The cause was cancer. Her death was announced by her agent and the Oregon Shakespeare Festival in Ashland, where she had acted for 22 seasons.
Coulson also had roles in the TV series "Portlandia," "August: Osage County" and "Into the Woods."
She had a long creative relationship with the director David Lynch, who created "Twin Peaks." He had initially cast her in the 1977 movie "Eraserhead," but she ended up working as an assistant director on the film instead.
Lynch is known for creating eccentric characters, and his setting for "Twin Peaks," a small town in Washington state, was peopled with them. But none were as peculiar as Coulson's Log Lady, who was forever cradling a log, which she treated as a cross between a pet and a portal to a supernatural world.
At her death she was set to reprise the role in a revival of the series, directed by Lynch, to be shown on Showtime next year.
Coulson was born in 1943 in Ashland, and grew up in Southern California. She met director Lynch in the 1970s while teaching an acting workshop in Los Angeles. She began acting at the Oregon festival in 1994 and went on to appear in more than 50 productions.
Coulson's marriage to the actor Jack Nance, who starred in "Eraserhead" and also appeared on "Twin Peaks," ended in divorce in 1976.
