"Today I lost one of my dearest friends, Catherine Coulson. 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," Lynch said in a statement.
She appeared in Lynch's 1974 short film "The Amputee" as a woman with both legs amputated.
Coulson also worked as first or second assistant camera on "Star Trek II: The Wrath of Khan", "Modern Romance", "Youngblood" and "Night on Earth."
Coulson was married to "Eraserhead" and "Twin Peaks" star Jack Nance. She later married Marc Sirinsky, with whom she had a daughter.
