As she gained mastery as an educator, she also became a prolific writer in paper and periodicals and a popular speaker. Soon she became a name among the intellectuals of London and became acquainted with some of the most learned and influential people of her time. Among them were Lady Ripon and Lady Isabel Margesson. They were the founders of a literary coterie, which came to be known as the Sesame Club. "The Times of London" of 26 October 1911, wrote about Margaret, "A trained teacher of exceptional gifts, she was one of a group of educationists who in the early nineties founded the Sesame Club." Famous writers, such as Bernard Shaw and Thomas Huxley, were some of the regular speakers at the Sesame Club. Discussions were held here on literature, ethics, politics, and other similar subjects.
