(d. 1949). She was the youngest daughter of David Masson (1822–1907), professor of English literature at University College London (1853–65) and professor of rhetoric and English literature at the University of Edinburgh (1865–95). She was a friend of R. L. Stevenson (1850–1894), the author of several books on Edinburgh and Scotland and of six volumes of fiction 1893–1911, including what now seem like sub-Wodehousean farces: In Our Town (1901), and Our By-Election (1908), in which Lord Harry Calthrop impersonates his uncle, Theophilus, a candidate at the Chucklebury by-election, who has been kidnapped by the other side and hidden on a yacht. She also edited several anthologies.
