In just six years, ACT UP, New York, a broad and unlikely coalition of activists from all races, genders, sexualities, and backgrounds, changed the world. Armed with rancor, desperation, intelligence, and creativity, it took on the AIDS crisis with an indefatigable, ingenious, and multifaceted attack on the corporations, institutions, governments, and individuals who stood in the way of AIDS treatment for all. They stormed the FDA and NIH in Washington, DC, and started needle exchange programs in New York; they took over Grand Central Terminal and fought to change the legal definition of AIDS to include women; they transformed the American insurance industry, weaponized art and advertising to push their agenda, and battled--and beat--The New York Times, the Catholic Church, and the pharmaceutical industry. Their activism, in its complex and intersectional power, transformed the lives of people with AIDS and the bigoted society that had abandoned them.
