In 1911, Margaret Potts was attending Durham University in Durham, England in the Education faculty. One of her professors returned to class after a trip to a symposium in Rome to tell the class about a remarkable new method of education for children and the founder of this method, Maria Montessori. Margaret Potts was so incredibly moved and knew this was to become her passion. While she was completing her education in England, Alexander Graham Bell was returning to North America after the same symposium to introduce the Montessori Method to his family and neighbours.
In 1914, Margaret and her husband William (also an educator) immigrated to Stettler, Alberta where they both taught at a normal school. In 1919, they moved to Calgary and founded The Montessori School in their three storey home. The classes operated on the main floor, many of the students boarded on the second floor and the Potts family lived on the third floor.
