Works & Achievements
Spier turns palm reading into a method of psychological analysis, at the prompting of Carl Gustav Jung.
His major work on palm reading as an indicator of psychological development, with a preface by C. G. Jung.
Spier ran workshops on psychochirology and personal development for clients who were in exile or under threat.
His therapeutic work with Etty Hillesum fed into her diary, which became a major testimony on spirituality in the face of the Holocaust.
Anecdotes
Before becoming a chirologist, Julius Spier worked for a long time in the world of business and banking in Frankfurt. Gifted with an exceptional visual memory for hands, he could reportedly recognize people from their palm prints alone.
Around 1934, Spier met the famous psychiatrist Carl Gustav Jung in Zurich. Jung encouraged him to turn his talent for reading hands into a genuine psychological method: this was the birth of “psychochirology.”
In February 1941, in Amsterdam, a young woman named Etty Hillesum came to consult him to ease her anxieties. Spier became her therapist, her mentor, and her lover; he holds a central place in her diary, which has become a great classic of Holocaust literature.
Spier died of cancer on 15 September 1942, the day before he was due to report for deportation. Etty Hillesum wrote that this death “in good time” had spared him Westerbork and Auschwitz — a fate she did not escape herself.
To analyze a hand, Spier took an imprint of it in black ink, like a set of fingerprints, then compared hundreds of these records to support his psychological interpretations.
Primary Sources
“He is about forty-five years old and, psychologically speaking, the most complex man I have ever met.” In her diary, Etty Hillesum describes the hold and the fascination that Spier exerts over her.
In it, Spier sets out his method of reading hands as a mirror of a child's psychological development; the work appears posthumously with an introduction by C. G. Jung.
Jung presents Spier's chirology as an empirical approach worthy of attention for grasping character, while keeping the caution of the scientist.

Typical Objects

An impression of the palm taken in black ink, like an enlarged fingerprint. Spier built up archives of these to compare features and support his interpretations.

A magnifying lens used to examine in detail the lines, mounts and creases of the palm. A precision tool of the methodical chirologist.

A notebook in which Spier recorded clinical observations and analyses of his clients. The medium for the shift from popular palmistry to a psychological approach.

A work gathering his method of reading hands for psychological purposes. The Hands of Children appeared posthumously, with a preface by Jung.

Daily Life
Morning
Spier devoted his mornings to receiving his clients in his apartment-office in Amsterdam. He took ink prints of their hands, then examined them under a magnifying glass while noting his observations.
Afternoon
The afternoon was dedicated to the comparative study of his archive of handprints and to writing up his analyses. He also prepared the lessons and group sessions he led for his students.
Evening
In the evening, Spier conducted longer interviews, halfway between psychological counseling and spiritual conversation. His exchanges with Etty Hillesum, made up of readings, reflections, and tensions, defined these hours.
Food
In Amsterdam under the Occupation, food grew scarcer as rationing was progressively imposed on Jews. Meals, simple and frugal, followed the everyday fare of the urban middle classes of the occupied Netherlands.
Clothing
Spier wore the understated attire of the cultured Central European gentleman: jacket, shirt, and tie. From 1942 onward, like all Jews in the Netherlands, he had to display the yellow star sewn onto his clothes.
Housing
He lived in an Amsterdam apartment that served both as a home and as a place of consultation. The modest space held his books, his archive of handprints, and the intimacy of his interviews.
