A parent who first sees the name Montessori on a nursery sign usually assumes it is the name of a programme, something like a brand of learning toys. Only later does it turn out that the name belongs to a real woman: a physician who spent decades watching children with a notebook in her hand and, from those observations, built a way of working that is now used in nurseries, preschools and schools on every continent. Her life was also far less calm than the wooden shelves and coloured beads in a classroom might suggest.
This article tells that story from a parent’s point of view. Each stage of Maria Montessori’s life ends with a question about what it left behind in today’s classroom — because almost everything a child does in a Montessori group can be traced back to a specific place and year.
Who was Maria Montessori?
Maria Montessori (1870–1952) was an Italian physician and educator who created the method of education that bears her name. She trained as a doctor of medicine — one of the first women in Italy to hold that degree — and came to education through her work with children with intellectual disabilities. In 1907 she opened the first Casa dei Bambini, or Children’s House, in Rome, and there she found that preschool children given the right environment and the freedom to choose their own work learn with a concentration adults did not expect of them.
Over the next forty years she developed the method in Spain, the Netherlands and India, trained teachers from all over the world and founded the organisation that still oversees training standards today. Three times, between 1949 and 1951, she was nominated for the Nobel Peace Prize. She died in the Netherlands at the age of 81. The Montessori method itself deserves its own article; this one is about the woman who created it.
Childhood and studies — medicine against the odds
Maria Montessori was born on 31 August 1870 in Chiaravalle, a small town in the province of Ancona in central Italy. Her father, Alessandro, was an official of the Ministry of Finance working at the state tobacco factory. Her mother, Renilde Stoppani, was well educated for her time, and it was she who encouraged her daughter’s ambitions. Her father loved Maria but disagreed with her educational choices — in his view, a woman could at most become a teacher.
Maria wanted something else. In 1890 she enrolled in natural sciences at the University of Rome and passed examinations in botany, zoology, experimental physics, histology, anatomy and chemistry. That diploma, together with extra study of Italian and Latin, opened the way to medical school in 1893. Before that, the professor of clinical medicine she had approached for advice had firmly discouraged her.
Her studies were not easy. Some fellow students and lecturers treated her with open hostility. Because a woman being present at a naked body in the company of men was considered improper, she had to carry out her dissections of cadavers alone, in the evenings, after classes. In 1896 she qualified as a doctor of medicine and became one of the first women in Italy to hold that title.
What did this leave in the classroom? Above all, a way of looking. Montessori was not an educator who invented a theory and then looked for children to fit it. She was a doctor used to observing, taking notes and testing hypotheses. That is why a teacher in a Montessori classroom watches first and acts second — a habit from medicine, not from pedagogy.
The clinic and the Orthophrenic School — where the method came from
After graduating, Montessori began working at the psychiatric clinic of the University of Rome. Between 1896 and 1901 she worked with children we would now describe as having developmental delays or intellectual disabilities. At the time, such children were often placed in institutions for adults and regarded as “uneducable”.
Montessori turned to the work of two French physicians: Jean Itard, who in the early nineteenth century tried to educate a boy found living in the woods, and Édouard Séguin, who developed ways of teaching children with disabilities through exercises of the senses and movement. She also read Fröbel and Pestalozzi. From Itard and Séguin she took the conviction that the hand and the senses are the way into the mind.
In 1900 the National League opened the Scuola Magistrale Ortofrenica in Rome — the Orthophrenic School, an institute training teachers of children with learning difficulties, with a laboratory classroom attached. Montessori was appointed co-director. The first class had 64 teachers. For two years Montessori worked with the children in that classroom and made materials for them: letters to touch, objects that differed in size, exercises in walking and using a spoon. Some of these children later passed the public examinations set for children without disabilities.
That was a turning point. Montessori asked herself the opposite question: if children considered unable to learn could make such progress, what could children without those difficulties achieve? The sensory exercises from that classroom grew into the later Montessori materials — the pink tower, the cylinder blocks, the rough and smooth boards. When a toddler fits cylinders into the holes of a wooden block today, they are using an idea born in a Roman clinic more than a hundred and twenty years ago.
Her son Mario — a story kept quiet for years
On 31 March 1898 Maria Montessori gave birth to a son, Mario. His father was Giuseppe Montesano, a doctor with whom she co-directed the Orthophrenic School. They did not marry. A married woman in Italy at the time would in practice have had to give up her professional work, and the Montesano family opposed the relationship because of class differences and insisted that the birth be kept secret. Montessori agreed on condition that neither of them would marry anyone else.
Montesano broke that agreement and married. Montessori felt betrayed and left the university hospital. She placed her son with a family living in the countryside and visited him, but could not raise him herself. Her biographers describe how deeply this affected her. She re-established contact with her son when he was a teenager, and from then on the two were inseparable.
Mario Montessori became his mother’s closest collaborator. Together they founded an international association, together they ran training courses, and together they lived through the war in India. After his mother’s death he led the development of the method until his own death in 1982.
The story resurfaces today in articles about “the doctor who abandoned her child”. The facts are less sensational: it was a decision forced by the customs of the time, when an unmarried mother lost her professional and social standing. Montessori later wrote about childhood with great tenderness, and her son spent his whole adult life at her side.
Casa dei Bambini — the first Children’s House in San Lorenzo
In 1906 Montessori received an offer that changed her life. She was asked to oversee the care of the young children of working parents in a new apartment building for low-income families in San Lorenzo, a working-class district of Rome. Montessori accepted, because she saw a chance to test her methods with children who had no disabilities.
The first Casa dei Bambini, or Children’s House, opened on 6 January 1907. Between 50 and 60 children aged from two or three to six or seven were enrolled. At first the room looked ordinary: a teacher’s table, a blackboard, a stove, small chairs and a locked cabinet for the materials. Montessori soon began to change it. She introduced light furniture sized for children, which they could carry themselves. She moved the materials onto low, open shelves. She added activities from everyday life: sweeping, hand washing, arranging flowers, caring for animals.
What she saw in San Lorenzo surprised even her. Children who had previously run about aimlessly could concentrate on a single task for a long time. They preferred working with the materials to rewards and toys. They kept the room tidy themselves when things had a fixed place. These observations gave rise to the idea of the prepared environment — a space designed so that a child can act independently.
Every Montessori classroom today, with its low shelf and child-height sink, is a distant relative of that room in a Roman apartment block.

How the method spread — from Rome to the United States and Poland
News of the Children’s House spread quickly. By 1909 foreign observers were visiting San Lorenzo, and Montessori described her work in the book Il metodo della pedagogia scientifica. In the United States it was published as The Montessori Method and became a bestseller. By the end of 1911 the method had been officially adopted in public schools in Italy and Switzerland, and by 1912 Montessori schools were open in Paris and many other European cities.
In 1913 Montessori led the first international training course for teachers in Rome. It had 83 participants, 67 of them from the United States. The same year saw a Polish translation of her book — so Poland was among the first countries where parents and teachers could read about the method in their own language. In December 1913 Montessori travelled to America on a lecture tour, supported among others by Alexander Graham Bell, and she returned there in 1915.
In the following years she worked mainly in Barcelona, where the Catalan government supported a school and a teaching institute bearing her name, and in the Netherlands, where more than two hundred Montessori schools were operating by the mid-1930s. In 1929, at the first International Montessori Congress in Elsinore, Denmark, Maria and Mario founded the Association Montessori Internationale, or AMI. Its purpose was to oversee schools, teacher training and the production of materials. Since 1935 its headquarters have been in Amsterdam.
For a parent, one practical point follows from this: the name “Montessori” is used by settings with very different levels of preparation, while there are organisations that have been safeguarding teacher-training standards for almost a hundred years. It is worth asking a nursery or preschool where its staff were trained.
Why did Maria Montessori leave Italy?
Maria Montessori left Italy in 1934 because her work had come into open conflict with Benito Mussolini’s Fascist government. In the early 1920s the government supported the method and funded training courses, but from 1930 there were growing disputes over money and over what schools should teach. Montessori spoke publicly about education for peace, which did not fit the ideology of a state preparing children for obedience and war.
In 1932 Maria and Mario were placed under political surveillance. In 1933 Montessori resigned from the state-chartered Opera Montessori, and in 1934 she left the country. Two years later the government ended Montessori activities in Italy. By then Barcelona had been her home for years, but the outbreak of the Spanish Civil War in 1936 forced another move — via England to Laren in the Netherlands.
This episode explains well what the method is at its core. A school in which a child chooses their own work, corrects their own mistakes and learns to cooperate with younger and older children raises independent people — and independent people did not suit a state that expected obedience above all from its citizens.
India and the war — cosmic education and the absorbent mind
In 1939 Montessori travelled to India to run a course at the Theosophical Society in Madras. She planned to return to Europe after a lecture tour, but in 1940 Italy entered the war on Germany’s side. The British interned Italian citizens in their colonies. In practice only Mario was interned — he rejoined his mother after two months — while Maria had to remain within the Society’s compound. The Montessoris stayed in Madras and Kodaikanal until 1946, although over time they were allowed to travel to give lectures and courses.
Those years proved very fruitful for the method. Mother and son developed a programme for children aged 6 to 12 called cosmic education: children learn about the world as a whole, in which plants, animals, people and the planet depend on one another. Materials for botany, zoology and geography were created, and between 1942 and 1944 Montessori ran a course for teachers of this age group.
In India Montessori also turned to the youngest children. In 1944 she gave a series of thirty lectures on the first three years of life. This work led to the book The Absorbent Mind (1949) — a description of how a young child absorbs language, movement and the customs of their surroundings without conscious effort. Every Montessori nursery draws on these lectures today, because they explain why working with children under three matters so much.
After the war Montessori returned to Europe. She lived in the Netherlands and continued to travel and lecture. She died on 6 May 1952 in Noordwijk aan Zee, at the age of 81.
What did Maria Montessori discover about children?
Maria Montessori discovered that a young child has an inner plan of development and actively seeks the activities they need at a given moment — provided the adult prepares a suitable environment and does not get in the way. Five ideas follow from this observation, and they still organise the work of every Montessori group and are easy to recognise in a child’s everyday behaviour:
Sensitive periods. In the first six years of life a child passes through phases of particular sensitivity to language, movement, order, small objects and sensory stimuli. During such a phase the child learns a skill with an ease they will never regain. The details and ages of each period are covered in the article on sensitive periods in the first six years.
The absorbent mind. Until about the age of six a child takes in the world differently from an adult — unconsciously, with their whole being, like a sponge. That is why what a child sees and hears every day matters so much.
The prepared environment. A child needs a space on their own scale: low shelves, real tools, a steady order. The adult does not teach directly — they prepare the conditions and demonstrate.
Polarisation of attention. In San Lorenzo Montessori noticed a girl who repeated an exercise with the cylinders dozens of times in a row without being distracted. Deep concentration was, in her view, the state in which a child truly develops — and the adult should not interrupt it.
Mixed-age groups. Younger children learn by watching older ones, and older children consolidate their knowledge by helping younger ones. This is how mixed-age groups in Montessori work.
A full description of how these ideas look in practice in a nursery and preschool can be found in the complete guide to the Montessori method for parents.
Myths about Maria Montessori — what is true
Several simplifications have grown up around Montessori, and they keep coming back online and in conversations between parents.
“She was the first woman doctor in Italy.” She was not. Other women had obtained medical degrees in Italy before her. Montessori was one of the first — which is quite enough to speak of breaking barriers, without adding a record that did not happen.
“She invented Montessori toys.” Montessori designed teaching materials, not toys. Each of her materials isolates a single quality — size, colour, weight, texture — and has a built-in control of error. Most products sold today as “Montessori toys” have little in common with her materials beyond the name.
“It is a method for children with disabilities.” That is indeed how it began — the Orthophrenic School. But all her later work, from San Lorenzo to India, concerned all children. The method works well in mixed groups, which is a strength rather than a limitation.
“Montessori was against play.” Montessori believed that children take their work seriously and find joy in it — which is why she spoke of “work” rather than “play”. She did not forbid play; she wanted adults to treat children’s activity with respect.
More misunderstandings about the method itself — from discipline to the move to school — are covered in the article on Montessori myths.
FAQ — common questions about Maria Montessori
When did Maria Montessori live? She was born on 31 August 1870 in Chiaravalle, Italy, and died on 6 May 1952 in Noordwijk aan Zee in the Netherlands. She lived to 81, more than forty years of which she devoted to developing her method.
Did Maria Montessori have children? Yes, one son — Mario, born on 31 March 1898. In his early years he was raised by a family in the countryside; from his teens he was at his mother’s side and became her closest collaborator and successor.
Did Maria Montessori win the Nobel Peace Prize? She did not win it, but she was nominated three times — in 1949, 1950 and 1951, six nominations in total. The nominations recognised her work on education for peace.
Was Maria Montessori a teacher? By training she was a doctor, not a teacher. She came to education through her work with children at the psychiatric clinic and the Orthophrenic School, and then at the Children’s House in San Lorenzo. She did, however, train thousands of teachers on courses in many countries.
What books did Maria Montessori write? The most important are Il metodo della pedagogia scientifica (1909), known in English as The Montessori Method, and The Absorbent Mind (1949). She also wrote, among others, Education and Peace (Educazione e pace, 1949) and The Discovery of the Child.
Where did Maria Montessori die? In Noordwijk aan Zee in the Netherlands, where she lived after returning from India. The Netherlands had been her second home since the 1930s — the headquarters of the Association Montessori Internationale have been in Amsterdam since 1935.
Was Maria Montessori on a banknote? Yes. Her portrait appeared on the Italian 1000 lire banknote issued in 1990. She has also been commemorated on postage stamps of countries including the Netherlands, India and Italy.
In closing
Maria Montessori left behind less theory than one might expect from the creator of a world-famous method, and more concrete observations: a child absorbed in the cylinders, a child putting a material back on the shelf unprompted, a child teaching a younger one to fasten their shoes. All these scenes can still be seen in a Montessori classroom today in almost the same form she described more than a hundred years ago.
