Anthony Fauci is an internationally renowned physician, scientist and immunologist, best known for his contributions towards the understanding of several immunodeficiency diseases, especially HIV and AIDS. Born to a pharmacist father in Brooklyn, he began delivering prescriptions as soon as he learned to handle a bike, developing an early interest in the subject. Eventually he earned his medical degree and began his career as Clinical Associate at the Laboratory of Clinical Investigation, an institution under the National Institute of Allergy and Infectious Diseases, National Institutes of Health, remaining with it for rest of his life. Initially working on polyarteritis nodosa and granulomatosis, he changed his focus to HIV/AIDS when he noticed an unusual infection in gay men, eventually finding hope in the form of treatment. Although he received brickbats, apparently for not doing enough, he courageously faced his detractors, making peace with them, having to face the same fate when Covid-19 began killing thousands.  Director of NIAID since 1984, he has also served as Advisors to seven Presidents since Ronald Regan.
