The discovery of insulin at the University of Toronto in 1921-2 was one of the most dramatic events in the history of the treatment of disease. Insulin, discovered by the Canadian research team of Frederick Banting, Charles Best, James Collip, and John Macleod, was a wonder drug with the ability to bring diabetes patients back from the brink of death. It was no surprise that in 1923 the Nobel Prize for Medicine was awarded for its discovery. In this engaging and award-winning account, historian Michael Bliss draws on archival records and personal adventures to recount the fascinating story behind the discovery of insulin - a story as much filled with fiery confrontation and intense competition as medical dedication and scientific genius. With a new preface by Michael Bliss and a foreword by Alison Li, the special centenary edition of The Discovery of Insulin honours the one hundredth anniversary of insulin's discovery and its continued significance a century later.

Harry Benjamin (1885–1986), a German-born endocrinologist, was a pivotal figure in the development of transgender medicine. He was physician to transgender pioneers such as Christine Jorgensen, the 1950s "Ex-GI" turned "Blonde Beauty" media sensation, and in turn, she and other collaborators helped to shape Benjamin's influential 1966 book, The Transsexual Phenomenon. Alison Li's much-needed biography of Benjamin chronicles his passion for hormones and his lifelong interest in sexology. Drawing from extensive research in archival documents, secondary sources, and interviews, Li tells the story of Benjamin's early ventures in gerontology and his later work with over a thousand transgender patients. Benjamin's contributions to treatment, education, research, and networking helped to create the institutional foundations of transgender medicine. Moreover, they set the stage for a radical reconsideration of gender identity, challenging us to reflect upon what it is to be male or female and to envision moving beyond these long-held categories.
