Maria Montessori appears to be the most famous educator in the world. She really revolutionized the world of education. Another woman had a great impact in the field of education, who wrote and lectured on education much earlier than Maria Montessori. Carefully reading the books of both educators and authors, they have so many principles in common, that one has to ask the question "Did they meet?" or " Did Maria Montessori copy from the books of Ellen White?" . Their style is different, their biographies are different, one Italian, the other American and yet both are outstanding women who changed the world. As Maria Montessori traveled a lot and several times to the USA, she might have met Ellen White, she might have read her books and articles but no evidence could be found to confirm this probability. Si it appears, that the only explanation for the stunning similarities in the educational principle by Maria Montessori and Ellen White is, that this is the truly scientifically correct method of education. And there are a lot of evidences for that.
