Anthony Fauci is arguably the most famous - and most revered - doctor in the world today. His role guiding America sanely and calmly through Covid (and through the torrents of Trump) earned him the trust of millions during one of the most terrifying periods in modern American history, but this was only the most recent of the global epidemics in which Dr. Fauci played a major role. His crucial role in researching HIV and bringing AIDS into sympathetic public view and his leadership in navigating the Ebola, SARS, West Nile, and anthrax crises, make him truly an American hero. His memoir reaches back to his boyhood in Brooklyn, New York, and carries through decades of caring for critically ill patients, navigating the whirlpools of Washington politics, and behind-the-scenes advising and negotiating with seven presidents on key issues from global AIDS relief to infectious disease preparedness at home. ON CALL will be an inspiration for readers who admire and are grateful to him and for those who want to emulate him in public service. He is the embodiment of "speaking truth to power," with dignity and results.
