The doctors told the father his newborn son would never walk normally, never speak meaningfully, and never live independently. They recommended institutionalization. The boy's brain was missing the corpus callosum — the band of nerve fibers that connects the right and left hemispheres. His cerebellum was malformed. He was, by every neurological measure available in 1951, severely and unusually damaged.
Fran Peek listened to the doctors. Then he took the baby home.
Kim Peek was born in Salt Lake City, Utah, on November 11, 1951. The medical establishment of his time and place, having examined the scans and the structural abnormalities, had concluded that the damage was incompatible with meaningful independent life. They told his parents to place him in an institution and not attempt to raise him at home.
Fran Peek did not accept the recommendation.
The first surprise came early. By the time Kim was a small child, his parents began to notice that his memory was working in a way that nothing they had read about described. By age three he was reciting passages from books his father had read aloud to him, word for word, after a single hearing. By the time he was a young man, he was reading independently and retaining, with near-perfect fidelity, almost everything he read.
His reading method was itself unusual and remained imperfectly explained by the researchers who later studied him. Peek could read both pages of an open book simultaneously, processing the left page with his left eye and the right page with his right eye independently. He could complete a standard book in approximately one hour. He retained substantially all of what he read.
Over the course of his life, he read and retained approximately twelve thousand books. The subjects ran from American history to Shakespeare, from the King James Bible to Western classical music, from sports statistics to the complete road atlas of the continental United States, from telephone directories to the dates of the European wars of the eighteenth century. He could answer historical questions immediately and completely. He could give the day of the week for any date specified by a questioner. He could describe driving routes between American cities in turn-by-turn detail without having driven them.
The leading theory among the researchers who studied him was that the absence of the corpus callosum — far from disabling his brain — had caused it to reorganize in ways that radically expanded its capacity for storage and retrieval. The two hemispheres, unable to coordinate in the standard fashion, had apparently developed independent and unusually capacious memory systems.
The same abnormalities that produced those abilities also produced profound physical and social impairments. Peek could not button his own shirt. He could not brush his teeth without assistance. He walked with significant difficulty. He had trouble with abstract language and often did not register sarcasm. He could not live independently in any practical sense.
His father provided what he could not provide for himself.
For fifty-eight years, Fran Peek dressed, bathed, fed, and accompanied his son through every routine of every day. He drove Kim to appointments and events. He sat beside him during lectures and presentations. He carried, without ever publicly describing it as a burden, the daily physical care of a man the medical establishment had told him to give up on before they left the hospital.
In 1984, at a conference for people with disabilities, Kim and his father met a screenwriter named Barry Morrow. Morrow asked Kim a question about American history. Kim answered instantly, including the day of the week of the event. Morrow asked another question. And another. The two men spent the rest of the afternoon together.
Morrow later said he came away with two distinct impressions. He had met a man with the most remarkable memory he had ever encountered. He had also met a man whose warmth toward the strangers he was speaking to — his genuine curiosity about their lives, his interest in their children, his attention to what people said to him — had nothing to do with the memory at all.
Morrow went home and began writing a screenplay.
The screenplay became Rain Man, directed by Barry Levinson and released in 1988. The film won four Academy Awards: Best Picture, Best Director, Best Actor for Dustin Hoffman, and Best Original Screenplay for Morrow and Ronald Bass. Hoffman, who had spent time with Peek during his preparation for the role of Raymond Babbitt, said in subsequent interviews that meeting Peek had changed his understanding of what the human mind was capable of.
It should be noted that the film's protagonist is depicted as autistic. Peek himself was not on the autism spectrum. His condition, reclassified in subsequent years, is now generally believed to have been FG syndrome — a rare genetic disorder distinct from autism. The fictional Raymond Babbitt and the real Kim Peek were not the same kind of person. But the film drew its emotional and intellectual energy from Peek's actual life, and the public conversation about savant syndrome it generated was substantially about him.
After Rain Man, Fran and Kim Peek began traveling together to speak at universities, hospitals, schools, and disability advocacy events across the United States and eventually around the world. Audiences came expecting a curiosity. The presentations followed a consistent pattern: people asked questions, Peek answered them, they tried to catch him in a mistake, they almost never succeeded.
What audiences remembered, however, was rarely the answers themselves.
What they remembered was what happened after. Peek stayed in the room. He moved through the crowd talking to people one by one. He asked them about their families, their children, their work, the books they were reading. He listened carefully to their answers and retained what they told him. People who encountered him years later at subsequent events found he remembered what they had told him the first time and asked about the children by name.
The man who could not button his own shirt had made an enormous number of strangers feel, briefly, that someone had actually seen them.
Kim Peek died on December 19, 2009, of a heart attack, at the age of fifty-eight. He was at home, with his father, who had outlived the boy the doctors had recommended institutionalizing at birth.
In the years before his death, Peek's brain had been the subject of substantial neurological study. NASA imaging specialists working with the family produced detailed scans of the unusual cortical structure. Researchers documented the absence of the standard inter-hemispheric architecture and described the alternative wiring that appeared to have taken its place. The research has continued since his death.
It has produced clues. It has not produced a complete explanation.
Kim Peek had been missing, at birth, the bridge between the two halves of his brain. His life was, by every account of the people who encountered him, an unusually connective one.
The doctors had been wrong about almost everything they told Fran Peek in the hospital corridor in November of 1951.
The single thing that made them wrong was the decision Fran Peek made, in that corridor, to take the baby home.
