Dr. Lawrence Jacoby is a highly eccentric psychiatrist who grew up in Hawaii and remains fascinated by it. Jacoby was seeing Laura Palmer as a patient prior to her murder. He is known for keeping cocktail umbrellas marked with dates of influential events that affected him. He is also a keen surfer. A recognizable trait of the Doc's were his glasses - one lens of which was blue, the other red (He said they made the world look three-dimensional). He also could do some conjuring tricks.
