Susan Sontag (January 16, 1933 – December 28, 2004) was an American writer and filmmaker, professor, literary icon, and political activist. Beginning with the publication of her 1964 essay "Notes on 'Camp'", Sontag became an international cultural and intellectual celebrity. Her best known works include On Photography, Against Interpretation, The Way We Live Now, Illness as Metaphor, Regarding the Pain of Others, The Volcano Lover and In America.
Sontag was active in writing and speaking about, or travelling to, areas of conflict, including during the Vietnam War and the Siege of Sarajevo. She wrote extensively about photography, culture and media, AIDS and illness, human rights, and communism and leftist ideology. Her often provocative essays and speeches sometimes drew criticism. The New York Review of Books called her "one of the most influential critics of her generation."
