Hermelin and O’Connor exerted a profound influence on their colleagues in the huts outside of Maudsley—both by the kinds of questions they asked and the discipline they brought to seeking answers. It was an ethic of inquiry that would persist as the researchers grew in numbers and took on still more novel questions. These included what seemed one of the most elementary of all: How common was autism?

It was not, and would never be, an easy question to answer. But London was the first place anyone would even try.

WHO COUNTS?

V
ictor Lotter left South Africa for London in 1963 to find out how much autism there might be in the world. He was late getting into psychology because he was late to enter the University of Cape Town—that lateness a result of a case of ankylosing spondylitis that hit him when he was fourteen. A severely painful autoimmune assault on the bones, it knocked him out of school for years and left him with a wicked curve in his back and a marked stutter in his gait. By the time he applied to the university, he was in his late twenties and mostly self-educated. He graduated with a bachelor’s degree, his school’s top prize for anthropology, and a job offer from Neil O’Connor, to work in the huts outside the Maudsley in London.

Lotter arrived, clean-cut and buttoned up in a jacket and tie, eager to take on something difficult for his PhD thesis. O’Connor was happy to oblige, giving him the gargantuan task of attempting to determine the prevalence of autism in Middlesex County. British health authorities were beginning to come under parental pressure to deliver support services to children with autism, so they had approached the team at the Social Psychiatry Unit to help them figure out how big the need was. Lotter was assigned to count the number of children with autism in a densely inhabited swath of England that skirted the former County of London.

Remarkably, no one, not even a veteran researcher like Neil O’Connor, had any idea how much autism existed—not in Middlesex County or anywhere else in the world. No one had ever attacked the question in any systematic way. It would have to be
an epidemiological
study, working with a sample population small enough to permit an actual count of everyone in it, yet big enough to have statistical significance. For that purpose, Victor Lotter decided to include only children born in the years 1953, 1954, and 1955, which gave him a set of 78,000 children, who at that point were between eight and ten years old.

Lotter would have to slog his way door to door, record office to record office, child to child, in person in order to uncover a good deal of the data he would need. That, in itself, was not a small task. But he faced another challenge of an entirely different kind.

Lotter was supposed to count kids with autism, but the question of whom to count—the matter of deciding whether a given individual had autism—was a mess of diagnostic confusion. When he turned to the medical literature to put together a simple list of defining symptoms for his survey, he discovered a tangle of competing syndromes, each with its own name, laying claim to the same traits Leo Kanner had described years earlier as being autism. In addition to Kanner’s “infantile autism,” there was also Loretta Bender’s “childhood schizophrenia,” Beata Rank’s “atypical child,” Margaret Mahler’s “symbiotic psychosis,” and a long list of other contenders, including “schizophrenic psychosis of childhood,” “dementia praecocissima,” “dementia infantilis,” “prepubertal schizophrenia,” “pseudo-psychopathic schizophrenia,” “infantile psychosis,” and “latent schizophrenia.” These terms were all being used interchangeably to describe children showing the same sorts of behaviors. As the British child psychiatrist Michael Rutter wrote in this period,
“It is by no means clear that all these authors are talking about the same condition.”

It had been twenty years since Leo Kanner laid down his first description of the condition of autism using Donald Triplett and the other ten children as a model. But during the intervening two decades, the outlines of the condition, the definition of what autism looked like, had blurred and wavered continuously as other expert voices chimed in. As early as 1955, Kanner himself was grousing about the fact that there were too many inaccurate, sloppy autism diagnoses being handed out based on little more than
“one or another isolated
symptom.” He fretted that his whole concept was being watered down by inconsistent standards. As he wrote later of that time, “Almost overnight the country seemed to be populated by a multitude of autistic children.”

Such a state of affairs could only be mystifying to people outside of psychiatry. Any lay observer might think that autism was autism—simply, objectively and always.

But that was not the case, and never would be.

There was no biological marker for autism (then or now): it could not be determined by a blood test or confirmed by a cheek swab. It could only be diagnosed through the observation and interpretation of a person’s behaviors, which meant it was next to impossible to avoid subjectivity in judgment. This was especially true when some of the key indicators Kanner listed were as vague as “an intelligent and pensive” expression and an “affectionate relation to objects.” Doctors interpreting behaviors by those measures were bound to disagree on whether to use the label of autism.

Autism was, and would long remain, a diagnosis in the eye of the beholder.


I
N THE END
, then, since no authority clearly spelled out for him what autism looked like, it came down to Victor Lotter to define that for himself. The burden was historic. A young psychologist-in-training with only a bachelor’s degree, Lotter, with guidance from his advisors, became the final arbiter of who counted and who did not in history’s first-ever prevalence study of autism.

Lotter designed a questionnaire—a basic tool of epidemiology—that he mailed out to every age-appropriate school in Middlesex County and every mental hospital, along with a letter to the staff in those places requesting that they use his checklist of behaviors and report back to him the names of any children who might be showing autistic traits. This would give him his first big pass at the population of 78,000 and help him narrow down his study population. His checklist included twenty-two items, such as

Spends most of the time on his/her own
Carries or collects curious objects such as stones or tins
Often uses a ‘special’ or peculiar voice
Very clumsy or awkward in bodily movements
Tries to examine things in odd ways…by sniffing or biting them

Lotter constructed this list by improvising. First, he relied on the two criteria Leo Kanner claimed were the essence of autism: extreme self-isolation and obsessive insistence on the
preservation of sameness. But he went beyond Kanner and borrowed a second diagnostic framework that went by the oddly delightful name
“Creak’s Nine Points.” Published in the
British Medical Journal
in May 1961, these nine criteria purported to define something called “schizophrenic syndrome in childhood,” which was another of those terms being used interchangeably for children with autistic behaviors.

A renowned London psychiatrist named Mildred Creak had chaired a panel of thirteen British experts, who spent nine months arguing over and negotiating a symptom list that added traits like “acute, excessive and seemingly illogical anxiety,” odd movements and postures, and “apparent unawareness of [one’s] own personal identity” to the overall picture. But the Nine Points, despite their creators’ best efforts, also proved vague and confusing in practice. “Apparent unawareness,” for example, was not a behavior that lent itself to precise and objective assessment. The list’s inherent blurriness was emphasized by the critic who disparaged them as “an artificially contrived cluster of symptoms.” Even Creak conceded that “subjective judgment” in their application “obviously led to divergences in interpretation.”

Nevertheless, using these nine points, along with his own interpretation of Leo Kanner’s thinking, Lotter cobbled together his own definition of what autism looks like, so that he could go out and count it.


T
HE RETURN RATE
on Lotter’s questionnaire was superb. By the time he finished opening up all the envelopes, 97 percent of the entire population of eight- to ten-year-olds in Middlesex County was accounted
for. In this first pass, teachers flagged some 666 children as hitting at least some of the marks on his twenty-two-item autism checklist. Relying on his advisors’ expertise and a closer review of each return, Lotter winnowed this group down to 88 children suspected of having autism, at least as he was defining it.

Next, he headed out to see each of these 88 children himself. He added to his list another 47 whose names he found by scouring the records at fourteen government medical centers for children who were not at school, most likely because of disability, for a total of 135 children. In the autumn of 1963, Lotter and his wife, Ann, who was also a psychologist and acting as his research assistant, launched the study. Together they went to public schools, mental hospitals, and the so-called training schools where some of these children had been placed. They observed each child, ran intelligence and language tests, and talked to the staff, who presumably knew the children as well as anyone. This process took months, but by the spring of 1964, it allowed the Lotters to eliminate more than half of the 135 children as candidates for the diagnosis of autism.

Next came the most emotionally trying part of the investigation as the Lotters began visiting the homes of the sixty-one children still remaining. The purpose of the home visits was to collect detailed medical and behavioral histories from the parents. Some of the children still lived at home, but in other cases, the child was absent, residing in an institution somewhere. In both situations, the Lotters could see the strain the families lived under and could feel their despair. Indeed, by virtue of this long journey and their tour of institutions and these households, the Lotters were collectively experiencing a larger dose of the reality of autism in the lives of families than anyone ever had before. Victor Lotter could not have called himself an autism expert when he started his project, but these months of study certainly made him one.

All sixty-one children still left on his list showed some autistic traits, but Lotter now had to make a judgment call of his own: which children’s traits added up to autism, for the purposes of his count?

His solution was yet one more improvisation—a kind of decree on his part. He simply split the children into two groups. He organized
their sixty-one names into a list that had the children with the highest levels of impairment at the top and those least impaired at the bottom. Then, under the thirty-fifth name, he drew a line. The children above the line, he would count as having autism; the children below the line, he would exclude. The full rationale of this selection was not clear even to Lotter himself. His top thirty-five, he wrote, were merely those “it was thought should be included.” But he was bluntly honest about the subjective nature of the choice he made.
“The point where a line is drawn,” he wrote, was merely “arbitrary.”


T
HIRTY-FIVE KIDS
out of 78,000. Or 4.5 in 10,000. It was autism’s first so-called prevalence rate. In subsequent years, its importance would grow—not just as a matter of historical interest but as the baseline against which all subsequent measurements of autism prevalence would be compared. Regardless of when or where later prevalence rates were published, they would invariably be cited in contrast to Lotter’s rate, often as if it were a solid, objective, and universal truth.

Lotter never saw it that way. He made it clear in his 1966 paper summarizing his survey that with only a few minor alterations in the assumptions he made along the way—a few different choices about where to draw the line around symptoms and their varying intensity—his 4.5 statistic could have come out significantly higher or lower.

If anything, Lotter’s intelligent and honest account of his epidemiological adventure exposed the quandary that would present itself whenever an attempt was made to measure the “rate of autism,” at that time and in the future. Blurred definitions led to unanswerable questions about whether different studies at different times were even talking about the same people. The inconsistency in deciding what autism looks like would persistently undermine certainty about who should be counted. Lotter made this point bluntly when summing up everything he had learned in his journey among the autism families of Middlesex County:
“ ‘True’ prevalence may not be a useful concept,” he wrote in 1966, “in the case of a syndrome…so poorly defined.”

That lesson, learned first in London, was a lesson that would repeat itself countless times over the next fifty years.

WORDS UNSTRUNG

S
cientific research is a mentor-driven field. Every established researcher can list the teachers upon whose shoulders he or she stands. Some can even remember the first meeting, that pivotal moment of connection where the fateful bond was formed.

For a young German woman named Uta Aurnhammer, that moment came at the Maudsley in 1964. A year earlier, Aurnhammer had received a diploma in psychology from Saarland University in Germany, though she had no real intention of making a career in the social sciences. That changed when she reached London. Initially, she came over only for a little English-language study, but the energy of 1960s London appealed to her, and she began looking for a way to stay longer. Tipped off about a slot in a work-study program in research psychology, she applied, but with little expectation of being accepted. To her great good fortune, not only was she chosen, but the position turned out to be in the Institute of Psychiatry, which meant she would be working at the Maudsley.
