The images of Mary Ellen Mark (1940-2015) are icons of documentary and humanistic photography. Mark's more than 20 books include Passport (1974), Falkland Road (1981) and Indian Circus (1993). Her 2015 book Tiny: Streetwise Revisited is a culmination of 32 years documenting Erin Blackwell (Tiny), who featured in Martin Bell's 1985 film Streetwise and Mark's 1988 book of the same name. A dedicated social documentarian and portraitist, she often turned her lens to marginalized communities-circus performers in India, street children in Seattle, the patients of Ward 81 at the Oregon State Hospital, and many others-invariably connecting profoundly with her subjects. Mark's work has been exhibited and published in magazines worldwide. Steidl has published The Book of Everything (2020) and Ward 81: Voices (2023).
