"DiMeo reveals Katherine Jones, Lady Ranelagh, as central to political, religious, philosophical and medical discussions, yet destined to be forgotten, because she obeyed the convention that women should not put their thoughts into print. DiMeo . . . has used her archival skills to trawl the papers of Ranelagh's mostly male contemporaries to uncover her role as a public intellectual. . . . DiMeo is scrupulous in tethering her observations to their archival sources. . . . That [Ranelagh's] story is gathered from the papers of her male relatives and associates highlights how easy it is for women to fall through the cracks of history."

Nature

"Ranelagh's works were never published nor were her manuscripts preserved . . . . To address this, historian Michelle DiMeo has written the first full-length biography of Ranelagh by gleaning details of her life from her correspondence and the archives and writings of her relatives and contemporaries. The result is a detailed account of this notable woman, her work, and her close, collaborative relationship with her brother Robert—set against the backdrop of the turbulent politics of the times, including the Irish and English civil wars."

Physics Today

"In Lady Ranelagh: The Incomparable Life of Robert Boyle’s Sister, Michelle DiMeo adroitly weaves together the extant evidence to bring this spectral figure to life. . . Through her careful reconstruction, DiMeo’s study shows, perhaps more fully than any extant volume, how a well-positioned seventeenth-century woman, who was formally excluded from the Church, universities, and Royal Society, could have a quiet say over the political and scientific direction of a nation."

Nuncius

"With this timely intellectual biography of the incomparable Lady Ranelagh, DiMeo presents a powerful portrait of an impressive intellectual figure and most remarkable woman, whose importance in the intellectual and scientific life of seventeenth century Britain went far beyond being Robert Boyle’s supportive and beloved sister."

Metascience

"For almost 400 years, it has been a struggle to find the right words to describe Katherine Jones, Lady Ranelagh. . . . In this engaging and deeply researched study, Michele DiMeo has taken up the gauntlet, and finally done justice to Lady Ranelagh. Choosing an approach that seems to cycle in and out of style in the history of science – that of the intellectual biography – DiMeo has captured Ranelagh as she moved through tumultuous times for nation, faith, and natural philosophy. And what emerges is a woman who occupied a place of respect in all of these, someone whose piety was unquestioned despite the personality that meant she was often ‘bold, sarcastic, and outspoken’ (p. 3)."

Annals of Science

"Lady Ranelagh was one of the most remarkable women of her day, and it is wonderful at last to have a book-length study of her. DiMeo meticulously weaves together the fragmentary surviving sources to provide a clear and convincing picture of a truly great figure. She illustrates the extraordinary range of eminent peers on whom Lady Ranelagh had real influence, throwing especially important light on her role in the emotional and intellectual development of her brother, the scientist Robert Boyle. Some of the most telling passages in the book deal with Lady Ranelagh's medical expertise, where she benefited from the lack of clear demarcation between professional and lay practice at the time. DiMeo also has important things to say about the significance of gender in intellectual life, illustrating how a woman like Lady Ranelagh retained an unexpectedly significant role behind the scenes, albeit one subsequently largely effaced. In all, this lucid and revealing biography is indispensable."

Michael Hunter, author of The Decline of Magic: Britain in the Enlightenment

"This is a thorough and carefully considered intellectual biography which will become a mainstay for those seeking to learn about 'philosophical' British women of the seventeenth century, at last letting us hear Lady Ranelagh's voice alongside contemporaries like Margaret Cavendish, Anne Conway, and Lucy Hutchinson as well as her famous brother. DiMeo offers a judicious, comprehensive view of the life and thought of her subject."

Harold J. Cook, author of The Young Descartes: Nobility, Rumor, and War

"In this sensitive and inspiring biography, DiMeo resuscitates from fragmentary and forgotten evidence a leading religiopolitical reformer and strategist during Britain’s civil wars, medical practitioner in a period of transformation, and natural philosopher at the founding of the Royal Society. Lady Ranelagh’s invisibility today, like that of other female intellectuals of the time, is ironically a tribute to her success in this role in the past. Without DiMeo’s sleuthing, Ranelagh’s ideas, arguments, and experiences—hidden in her letters, within her brother’s writings, and in the many dedications acknowledging her collaboration—would be forgotten forever."

Pamela H. Smith, Seth Low Professor of History, Columbia University

"Katherine Jones, Lady Ranelagh, was a remarkable woman who played an important role in the intellectual and political circles of her day. However, the loss of most of her writings has meant that, until now, she has been remembered (if at all) only as the sister of her famous brother, the natural philosopher Robert Boyle. DiMeo's excellent biographical study is a feat of historical detective work and reconstruction, which restores Katherine Ranelagh to visibility as a prominent collaborator and mentor at the center of events in the scientific and political history of seventeenth-century Ireland and England."

Sarah Hutton, University of York

"Michelle DiMeo has filled an important gap with this first book-length biography chronicling [Ranelagh's] remarkable life. DiMeo’s book offers fascinatingly novel insights into one of the most important and influential female figures in seventeenth-century Britain and provides a fresh perspective on wider questions within the history of (women in) science. The book also makes significant methodological contributions, helping to advance research on other under-studied and sparsely documented women in science."
