Ellen Mary Knox

Knox taught briefly at Cheltenham Ladies' College. In 1894, she became first principal of Havergal College, an Anglican girls' school, when it opened in Toronto. She served in that position for thirty years, until her death in 1924.^[6] "The success of the school during its first thirty years was largely the result of her drive and personality," concluded a biographer of her colleague, Henry John Cody.^[7]

Published works by Ellen Mary Knox include Acts of the Apostles: Bible Lessons for School Children (1908),^[8] Canadian Education and the War, The Girl of the New Day (1919), about the role of young women in Canada after World War I,^[9][10] and A Girl's Week of Prayer (1920).

Knox's notable kin included her brother's children, editor E. V. Knox, author Winifred Peck, codebreaker Dilly Knox, Anglican clergyman Wilfred Knox, and Roman Catholic priest Ronald Knox. Ellen Mary Knox died in 1924, aged 65 years.^[11]
