The very first official Montessori training course was held in Rome, Italy in 1913. While the course attracted international attendees, the majority were from America. Maria Montessori taught the theory lessons in Italian at her home and the practical lessons/demonstrations took place at Casa dei Bambini (or The Children’s House), the first Montessori School, which she had established in 1907 in Rome.
During this time, Dr. Montessori experienced significant changes in her personal life. Her mother, Renilde Stoppani, passed away in 1912, and Montessori was reunited with her son, Mario, who had been raised by a foster family since infancy. Maria Montessori had never married, and due to societal expectations and her professional ambitions, she had arranged for Mario to be raised by others. He later became an integral part of her work, continuing her legacy.
Interest in the Montessori educational approach was particularly strong in the United States, where prominent figures such as Alexander Graham Bell, Thomas Edison, Helen Keller, and Margaret Woodrow Wilson (President Wilson’s daughter) supported her work. The American journalist Samuel McClure convinced Montessori to travel to the U.S. for a three-week lecture tour in 1913, which he described as a journey “for the conquest of the world”. Dr. Montessori boarded the SS Cincinnati in Naples for a 12-day voyage to America, where she delivered lectures, including two at Carnegie Hall in New York. It has been reported that President Woodrow Wilson and his daughter were so impressed by the Montessori Method that a Montessori classroom was installed in the White House. During her travels, Montessori kept personal and inspirational notes that have since been translated into English and published in Maria Montessori Sails to America: A Private Diary, 1913, by Carolina Montessori, Dr. Montessori’s great-granddaughter.
Journalist Samuel McClure, 1913
The Evening Star newspaper published an article in 1913 highlighting Dr. Alexander Graham Bell and his wife Mabel’s advocacy for making Washington, D.C., America’s headquarters for Montessori education. Anne George, the first American graduate of Dr. Montessori’s training program in Rome, helped introduce the Montessori Method to the U.S. She was the Director of an early Montessori school in Washington, D.C., with the support of the Bell family. Montessori’s ideas ignited a debate in America about traditional education versus the Montessori approach, which emphasized children’s independence and self-directed learning rather than a rigid, teacher-driven curriculum. Her visit to the U.S. made such a profound impact that she was urged to return as soon as possible to lead more lectures and training programs, as unauthorized training centers were emerging. If Maria Montessori was unable to come herself, it was requested that she send someone who was qualified to train teachers in her method.
In 1915, Maria Montessori returned to the United States, this time accompanied by her son, Mario. She addressed thousands of educators in Los Angeles, San Francisco, and San Diego and participated in the Panama-Pacific International Exposition (“World’s Fair”) in San Francisco. One of the most famous moments of this visit was the “Glass Classroom”, a demonstration where 30 children worked independently in a transparent, glass-walled environment, allowing spectators to witness the Montessori Method in action. During this visit, Montessori wrote letters that have since been preserved and published in Maria Montessori Writes to Her Father: Letters from California, 1915, also translated by Carolina Montessori. Dr. Montessori’s California lectures have been archived, with English translations by Robert G. Buckenmeyer, who also compiled articles she published in various newspapers.
After Maria Montessori’s passing in 1952, her son Mario continued to spread her educational philosophy. In 1960, he appointed Nancy McCormick Rambusch to establish the American Montessori Society (AMS), which played a crucial role in expanding Montessori education in the United States. Rambusch founded Whitby Montessori School in Greenwich, Connecticut in 1958, and today, there are more than 15,750 Montessori schools worldwide.
At The Montessori Children’s Academy (MCA), we continue to honor Maria Montessori’s legacy by celebrating “Montessori Education Week” alongside schools around the world. During this special week in February of each year, MCA students demonstrate Montessori Practical Life exercises for parents and visitors, sing Montessori songs, study Italy, review the timeline of Dr. Montessori’s life and work, and practice the “Silence Game”, a mindfulness exercise inspired by Montessori’s teachings on peace. For Montessori Education Week 2025, parents were also invited to observe their children’s classroom activities, and the celebrations concluded with a pizza party at Nonna’s Pizza and Italian Restaurant in Florham Park.
