Henrietta Müller

[1] As a child, she received little in the way of formal schooling but spoke six languages and was admitted to Girton College at the University of Cambridge in 1873.

[2][3] During her term, she convinced the board to employ female workers—"cannily pointing out that this would save money since women were paid less than men"—and was involved with Annie Leigh Browne and Mary Stewart Kilgour in establishing the first women's residence hall (College Hall) in Bloomsbury before leaving the board in 1885.

[2] Müller wrote numerous articles for the Westminster Review which discussed the empowerment of unmarried women and criticised contemporary marriage.

[2] After meeting Swami Vivekananda at the Parliament of the World's Religions in 1893 she edited a number of his books, including Lectures from Colombo to Almora, published in 1897.

Her estate was left to her sister Eva McLaren, also a women's rights activist, with no mention of her adopted son in her will.
