Pierre Janet. A Short Biography. Introduction 

Pierre Janet (30 May 1859 – 24 February 1947) was born in Paris into an educated middle-class family. His father, Jules Janet, a Parisian lawyer, and his devout Catholic mother, Fanny Hummel, set the stage for Pierre’s intellectual journey. 

Paris, with its Hôpital de la Salpêtrière, was the birthplace of modern psychiatry. It became renowned throughout Europe thanks to Philippe Pinel and Martine Charcot. Pinel’s “chain liberation” of the mentally ill is often seen as breakthrough to a human concept of psychiatry. On the other hand, Charcot, known as “the Napoleon of neurosis “, was the gratest contributor to the 19th century development of modern psychology and neurology. Later on, Pierre Janet’s research gave a noticeable impuls for Sigmund Freud Psychoanalysis.

Janet’s early interests fluctuated between a fascination with the natural sciences, especially botany, and mystical topics. Seeking for answers, he turned to philosophy, influenced significantly by his uncle Paul Janet, an esteemed philosopher of the spiritualist school. This spiritualist philosophy, dominant in nineteenth-century France, left an enduring mark on young Janet’s academic pursuits. 

Pierre Janet’s Studies

Pierre Janet attended the renowned Collège Sainte-Barbe in Paris, where Ignatius of Loyola and John Calvin also studied. In 1879, Janet was admitted to the prestigious Ecole Normale Supérieure, where he graduated second in his class in the Agrégation de Philosophie in 1882.

Initially, the young Janet was uncertain whether he was more drawn to being a teacher or a doctor. In 1879, he followed in his uncle’s footsteps, entering the prestigious École Normale Supérieure to study philosophy, where he encountered future impactful philosophers such as Émile Durkheim or Henri Bergson.

After his philosophical studies he taught philosophy in Le Havre, while also volunteering at the hospital there. Janet, a keen observer, eventually focused on several psychiatric cases (“hysterical women”) and used hypnosis, which was fashionable at the time and familiar to Janet from lectures he attended in Paris.

From 1889 to 1893 he studied medicine at the University of Paris. At the same time, he taught philosophy at the Sorbonne and the Collège de France. He completed his medical degree with a disertation L’État mental des hystériques (The Mental State of Hystericals).

“Psychological Automatism”

In 1889, Janet defended a ground-breaking thesis, “L’automatisme psychologique” (Psychological Automatism) which laid the foundation for his influential career. He described psychological automatism as a state wherein an individual’s actions, thoughts, or speech unfold involuntarily, without conscious control or awareness. This concept delves into various phenomena such as automatic writing, trance states, and other manifestations of dissociation, topics that he would elaborate on further in his career.

His observations drew significant attention in Paris. Even the famose physician Martin Charcot was impressed by the young Janet and his insightful observations. At Charcot’s invitation, Janet got appointed by Charcot to a director of the Salpêtrière Hospital’s psychological laboratory where he worked until 1902. He retired from work in the 1930s and lived until his death in 1947 in his native Paris.

Janet’s Journey from Parapsychology to a Scientific Psychology

Although trained as a philosopher, Janet consistently aimed to focus clearly on the reality he encountered to avoid speculation. He was interested not only in the concrete symptoms of his patients and the content of their thoughts but also in their life stories. For him, there was a “psychological reality” significantly influenced by biographical factors. He realized early that many of the hysterical wemen had traumatic life events. Janet’s experiments with Léonie, an adept hypnotic subject, gained his attention and led him to abandon parapsychology for a more scientific approach. 

Janet’s Academic Ascent

His marriage to Marguerite Duchesne in 1894 marked a significant influential period in his career. Janet’s academic ascent included teaching experimental psychology at the Collège de France, establishing the Société de Psychologie in 1901, and co-founding the Journal de Psychologie Normale et Pathologique in 1904.

Studies on Hysteria

Janet furthered his education in medicine, earning acclaim for his 1893 thesis, “L’État Mental des Hystériques.” This thesis contributed to the debate against Hippolyte Bernheim’s psychological perspectives on hysteria and hypnosis. At the time, most contemporaries of Janet linked hysteria solely to sexual trauma, whereas Janet proposed a more nuanced understanding. Working as the head of the psychological laboratory at Salpêtrière he observed numerous patients with hysteria and documented the symptom of dissociation. This marked a pivotal moment in the evolution of clinical psychology. 

Janet’s Theory of Hysteria

According to Janet, traumas were experiences that overwhelmed personal coping abilities and were split off to avoid becoming too powerful. However, these traumas remained in memory and threatened to resurface as memories, leading to severe impairments. These split-off parts of the personality led an autonomous existence and reappeared “automatically.” Since other people successfully coped with similar experiences, there had to be additional factors contributing to actual traumatization. In Janet’s view, mental illness occurs when the mental force of trauma exceeds the mental force of one’s coping mechanisms. Only then would these experiences become “pathogenic.” Janet called this the “narrowing of the field of consciousness” or “weakness of psychological synthesis.” The affected individuals had to be marked by a depressive structure, which could pre-exist but also stem from the traumatic experience itself.

Those who could not cope with such traumatic experiences tended to dissociations and multiple personality structures. Even though the term “dissociation” did not originate with Janet, he gave it central importance and emphasized its connection to trauma. Janet’s concept of dissociation quickly became well-known but eventually faded.

Pierre Janet. Biography. Summary

During his life Pierre Janet held global acclaim as a psychologist and psychotherapist. He pioneered in the study of psychological analysis, profoundly shaping Freud’s later psychoanalytic theories.

Janet’s influential career at the Collège de France, from 1902 to 1935, solidified his status as an important figure in French psychology. Simultaneously, he continued his medical and psychotherapeutic practice. During this time, he accumulated a wealth of clinical records that were unfortunately destroyed per his wishes after his death. The precise motive behind this decision was not explicitly documented. Despite publishing 148 monographs and journal articles, his work, unlike Freud’s, remains relatively unknown today. It’s not uncommon for scientists who once made significant discoveries to fade from professional recognition. Pierre Janet experienced such a fate.
