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.


Twin Peaks (1990-1991)Edit

Season 1Edit


The day after the death of Laura Palmer, Dr. Lawrence Jacoby excitedly tells hospital staff about a fish he had caught when he sees Sheriff Truman and a man in a suit on the elevator. He rushes to them, but the door closes and he takes the stairs to meet them. He notes that Laura's death was a terrible tragedy and he is introduced to the man in the suit, FBI Special Agent Dale Cooper. He says that Laura was a patient of his and wants to assist them in the morgue, which the lawmen do not allow, as it is against procedure. He also says that Laura's parents do not know that she had been seeing him.

Episode 1Edit

Jacoby plays a tape made for him by Laura. He takes half of a heart-shaped necklace out of a coconut and begins crying.

Episode 3Edit

He coaxes Johnny Horne into removing his headdress for Laura's funeral.

Jacoby does not attend the funeral, but comes to the cemetery at night, where he encounters Agent Cooper. He calls himself a terrible person, saying he does not truly care for his patients until Laura, so he could not bring himself to come to the funeral.

Episode 4Edit
Doctor Jacoby

Jacoby sits in the sheriff's station conference room with Agent Cooper, doing magic tricks with golf balls. Cooper asks him if Laura had been seeing him due to her cocaine problem, but he does not answer the question due to doctor-patient confidentiality, but insists he ask a less-specific question. Jacoby is then asked if Laura's problems were sexual and he answers that every problem is of a sexual nature and tells him about the ancient Hawaiians using the ginger plant in the same way Laura used cocaine. But he tells Cooper that even he could not break down the walls surrounding Laura's secrets. The sheriff enters and asks him if Laura ever discussed Bobby Briggs or James Hurley, to which he responds that they were boys and Laura was a woman. Cooper states that Laura had sex with three men the night she was murdered, but Jacoby denies being one of them, but said he followed a man Laura spoke about that drove a red Corvette. Cooper than lets him go.

Episode 5Edit

He meets with the Briggs family for a counseling session, where they discuss Bobby's behavior. Jacoby wishes to see him alone, telling the confused Major Briggs that he will need to see each of them individually. He brings up the first sexual encounter between Laura and Bobby, the latter having cried while Laura laughed at him. Bobby tells him that Laura wished to die and says he believes Laura had a secret that made her want death. He also learns that Laura corrupted Bobby, making him sell drugs to provide for her addiction.

Episode 6Edit

Jacoby watches Invitation to Love in his office when he gets a phone call from someone claiming to be Laura. She tells him to go to his door. Taking a gun, he finds an envelope with a video tape inside. He plays it, seeing Laura holding the latest newspaper. He picks his phone back up and Laura tells him to meet her at Sparkwood and 21 in ten minutes. He looks over the tape again and notices the park's gazebo and he leaves.

Episode 7Edit

He arrives at the park and watches Laura until he is beaten down by someone and suffers a heart attack as Laura leaves with James Hurley and Donna Hayward.

He is taken to the hospital, rambling incoherently.

Season 2Edit

Episode 8Edit

Hey lays in his bed as Sheriff Truman and Agent Cooper arrive. When questioned on how he came into possession of Laura's necklace, he recounts following James and Donna and digging up the necklace they has buried as a keepsake. He also notes that the last time he saw Laura, she seemed to have made peace with herself and was ready to die. He is also questioned if he saw anything when Jacques Renault was killed in the hospital the previous night. He notes having smelled scorched engine oil.

Episode 10Edit

He lays in his hospital bed, which is now filled with Hawaiian decor. He introduces them to his wife, Eolani, who massages him. He has Truman hold a stone as Cooper hypnotizes him. Cooper asks him what he saw the night Jacques Renault was killed, and describes the murder. He states that he knows the murderer.

Episode 17Edit

Following the funeral for Leland Palmer, Jacoby attends the reception at the Palmer home. Palmer had died in custody after being arrested for the murder of his daughter. Major Briggs approaches him, welcoming him back to town after his absence to recover from his heart attack.

He and Ed convince the staff at Twin Peaks High School to admit Nadine into the student body since she believes she is a teenager, following a suicide attempt.

Episode 21Edit

Jacoby observes Ben Horne, who operates a miniature Civil War re-enactment, believing himself to be General Robert E. Lee.

He later goes to the sheriff's station, where he dismisses any curses within Lana Milford that lead to the death of her husband Dougie Milford, despite claims by his brother, Dwayne. Instead, he says that she has a heightened sexual drive. As they leave to go bowling, they are confronted by Dwayne, who is armed with a rifle. Cooper commands the mayor and Lana to have a private discussion. Meanwhile, the rest of them men stand outside until Cooper gives them the go-ahead to enter, where they find Lana kissing Dwayne, who announces that they will be adopting a child.

Episode 22Edit

After hearing Ben muse about Stonewall Jackson, Jacoby tells Audrey and Jerry that his experiment in showing Ben to the public did not help his mental state. When Audrey requests he return Ben to the "real world," he suggests they re-enact the surrender at Appomattox.

At the surrender, Jacoby plays General Grant and surrenders, despite the historical inaccuracy. Ben then collapses, then comes to, believing his Civil War to have been a dream.

The Secret History of Twin PeaksEdit

As a child in 1939, Jacoby's family moved from Twin Peaks to Hawaii, where his father was stationed with the United States Navy. His parents divorced the next year, and he remained in Hawaii with his mother (who changed her name from Esther to Leilani), while his father and brother returned to Twin Peaks.

In 1981, he moved back to Washington following his mother's death to study Native American tribes and to care for his brother, who had been diagnosed with multiple sclerosis.

Jacoby's medical license was revoked following the Laura Palmer investigation and he returned to Hawaii to work on his memoirs.
