Inspiring us right now: Diane Arbus’ classic yet still mesmerizing 1966 portrait, A Young Man in Curlers at Home on West 20th Street, N.Y.C., on view starting today at Martin-Gropius-Bau in Berlin. It’s one of 200 iconic images from the seminal mid-century American photographer, whose unflinching, unapologetic exploration of society’s fringe paved the way for documentary-style artists ranging from Cindy Sherman to Catherine Opie to Terry Richardson.
