UPDATED with statement from David LynchCatherine E. Coulson, a camera assistant and actress best known for playing the Log Lady on Twin Peaks, died today of cancer. She was 71.

“Today I lost one of my dearest friends,” Twin Peaks creator David Lynch said in a statement. “Catherine was solid gold. She was always there for her friends. She was filled with love for all people — for her family, for her work. She was a tireless worker. She had a great sense of humor; she loved to laugh and make people laugh. She was a spiritual person, a longtime TM meditator. She was the Log Lady.”

Coulson, who had a longstanding association with Lynch, worked as a camera assistant on Lynch’s debut, the cult classic Eraserhead. It was during that film that the two came up with the idea that would eventually become the iconic Twin Peaks character, which she played on the series as well as the 1992 film prequel Twin Peaks: Fire Walk With Me. She was set to reprise the character on the upcoming Twin Peaks relaunch on Showtime.

Among her other credits as a camera assistant, Coulson worked on Star Trek II: The Wrath of Khan, Modern Romance, and Night on Earth. Among her other acting credits, she appeared in an episode of Portlandia, as well as Lynch’s short film The Amputee. She lived in Oregon, where she was an integral part of the Oregon Shakespeare Festival.

She was first married to actor Jack Nance, who starred in Eraserhead and Twin Peaks, and later to Marc Sirinsky. Sirinsky and Coulson had one child together, a daughter.
