Mary Proctor: An astronomical popularizer in the shadows

The popularizer of astronomy Mary Proctor was well known in her days but has been little remembered since. A prominent lecturer and author, Proctor was trained in the craft of science writing by her father, Richard Proctor. She ‘held the very first place in the profession as a woman’ and promoted the role of women in science throughout her career. Her life illuminates many themes. Mary Proctor spanned the period between entrepreneurial science popularizers and professional science communicators. I suggest that one of her most important legacies is as an early pioneer of the practices of science journalism in the early twentieth century when the relations between science and society were in flux. Yet her legacy has been largely overlooked. A study of Proctor's life reveals multiple interests, diverse opportunities and the way that people are differently remembered.
