Starting in the early 80s, Donna Ferrato has spent a decade photographing battered women:

[Her photographs] helped change how domestic violence was viewed in America. She spent the 1980s living with victims and their abusers, staying in battered-women’s shelters and accompanying police officers rushing to domestic conflicts.

The result was her seminal book, “Living With the Enemy,” which Aperture has reprinted four times over the last 20 years. It is the rarest of photographic projects: one that has significantly affected the problem it documents, helping to change laws and establish and finance domestic violence shelters throughout the country.
