Maria was born in Rome, Italy in 1870 to an upper middle class family. Her parents wanted her to be a housewife, as were most women of her generation, but Maria had other ideas. In 1896, she became the first female doctor in all of Italy. It was very hard for her to become a doctor because all of the other doctors were men. The men made fun of her and threatened her. All she could do was block them out. Because of this, Maria never married.
After that she started working with disabled children. Maria devised a new method of education because she thought the method in place at the time was not serving the needs of the children. She observed that children have developmental periods in which they are primed to learn different things.
Her approach to teaching disabled children was very different than anyone else’s at the time. Instead of the traditional methods that included reading and reciting, she taught the children by using concrete materials, which worked very well. Learning was not memorizing but sensing and experiencing things. The disabled children scored higher on the same test that the regular children took; then she got an idea: “Why can’t normal children benefit from the same method?” So she opened a Casa dei Bambini or Children’s House in the slums of Rome. She moved around Europe for a while until she settled in Italy again after World War II and the fascist government was no longer. Montessori had a big impact on education; because her methods were different, she opened up a new light on the subject.
She died in 1952, but her legacy, with over 150 schools in the US and even more worldwide, lives on.
