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.
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.
On February 21, 1989, Jacoby called Laura Palmer, saying that she did not come to see him, and she said that this was due to her being with Johnny Horne on his birthday. He asked her to make him a tape and she said maybe the following day. He then asked for her to send him a kiss, but she hung up.
Two days, Laura was found dead. At the hospital, Jacoby excitedly told its staff about a fish he had caught until he saw Sheriff Harry S. Truman and a man in a suit on the elevator. He rushed to them, but the door closed and he took the stairs to meet them. He noted that Laura's death was a terrible tragedy and he was introduced to the man in the suit, FBI Special Agent Dale Cooper. He said that Laura was a patient of his and wanted to assist them in the morgue, which the lawmen did not allow, as it was against procedure. He also said that Laura's parents did not know that she had been seeing him. Later in the evening, he followed a red Corvette, then later Laura's best friend, Donna Hayward, and secret boyfriend, James Hurley, who buried half of a heart necklace given to James by Laura. Jacoby dug up the necklace and took it as a keepsake.
The next day, in his office, Jacoby played a tape made for him by Laura. He took the necklace out of a coconut and began crying.
Two days later, he coaxed Johnny Horne into removing his headdress for Laura's funeral.
Jacoby did not attend the funeral but went to the cemetery at night, where he encountered Agent Cooper. He called himself a terrible person, saying he did not truly care for his patients until Laura, so he could not bring himself to come to the funeral.
Jacoby sat in the sheriff's station conference room with Agent Cooper the following day, doing magic tricks with golf balls. Cooper asked him if Laura had been seeing him due to her cocaine problem, but he did not answer the question due to doctor-patient confidentiality but insisted that he ask a less-specific question. Jacoby was then asked if Laura's problems were sexual and he answered that every problem is of a sexual nature and told him about the ancient Hawaiians using the ginger plant in the same way Laura used cocaine. But he told Cooper that even he could not break down the walls surrounding Laura's secrets. The sheriff entered and asked him if Laura ever discussed Bobby Briggs or James Hurley, to which he responded that they were boys and Laura was a woman. Cooper stated that Laura had sex with three men the night she was murdered, but Jacoby denied being one of them but said he followed a man Laura spoke about that drove a red Corvette. Cooper then let him go.
A day later, he met with the Briggs family for a counseling session, where they discussed Bobby's behavior. Jacoby wished to see him alone, telling the confused Major Garland Briggs that he would need to see each of them individually. He brought up the first sexual encounter between Laura and Bobby, the latter having cried while Laura laughed at him. Bobby told him that Laura wished to die and said he believed Laura had a secret that made her want death. He also learned that Laura corrupted Bobby, making him sell drugs to provide for her addiction.
The following evening, Jacoby watched Invitation to Love in his office when he got a phone call from someone claiming to be Laura. She told him to go to his door. Taking a gun, he found an envelope with a videotape inside. He played it, seeing "Laura" holding the latest newspaper. He picked his phone back up and "Laura" told him to meet her at Sparkwood and 21 in ten minutes. He looked over the tape again and noticed the park's gazebo and he left.
He soon arrived at the park and watched "Laura" until he was beaten down by someone and suffered a heart attack as "Laura" left with James and Donna.
He was taken to the hospital, rambling incoherently.
The next day, he laid in his hospital bed as Sheriff Truman and Agent Cooper arrived. When questioned on how he came into possession of Laura's necklace, he recounted following James and Donna and digging up the necklace they had buried. He also noted that the last time he saw Laura, she seemed to have made peace with herself and was ready to die. He was also questioned if he saw anything when Jacques Renault was killed in the hospital the previous night. He noted having smelled scorched engine oil.
Two days later, he laid in his hospital bed, which was then filled with Hawaiian decor. He introduced Agent Cooper and Sheriff Truman to his wife, Eolani, who massaged him. He had Truman hold a stone as Cooper hypnotized him. Cooper asked him what he saw the night Jacques Renault was killed and he described the murder, stating that he knew the culprit: Leland Palmer.
After his release from the hospital, he went to his home in Hawaii to recover.
Following the funeral for Leland Palmer a week later, Jacoby returned to Twin Peaks and attended the reception. Palmer had died in custody after being arrested for the murder of his daughter. Major Briggs approached Jacoby him, welcoming him back to town.
He later went to the sheriff's station, where he dismissed any curses within Lana Milford that lead to the death of her husband, Dougie Milford, despite claims by Milford's brother, Dwayne. Instead, he said that she had a heightened sexual drive. As they left to go bowling, they were confronted by Dwayne, who was armed with a rifle. Cooper commanded the mayor and Lana to have a private discussion. Meanwhile, the rest of the men stood outside until Cooper gave them the go-ahead to enter, where they found Lana kissing Dwayne, who announced that they would be adopting a child.
After hearing Ben muse about Stonewall Jackson, Jacoby told Audrey and Jerry that his experiment in showing Ben to the public did not help his mental state. When Audrey requested he return Ben to the "real world," he suggested they re-enact the surrender at Appomattox.
Days later, Jacoby sat down with Ed and Nadine Hurley, so the former could ask the latter for a divorce. However, she was confused, as she believed they were only dating.
At the Hurley home a few days later, Nadine showed some of her wrestling highlights to Dr. Jacoby, Ed, Norma, and Mike. Jacoby said he had gathered them together, as he felt the divorce would be easier if all parties involved discussed their feelings. Ed told Nadine that he and Norma planned to get married, to which Nadine responded that she and Mike would be doing the same.
Jacoby's medical license was later revoked and he returned to Hawaii to work on his memoirs.
