If honesty is an unmade bed, the artist Tracey Emin pulled back the sheets quite some time ago. Since the early 1990s, her insistence on honesty—at times brutal—has been a source of both fascination and controversy. Working across media, she has made neon, embroidery, drawing, installation, and sculpture feel equally confessional. Emin has also undergone a series of transformations: from rebel to dame, from tabloid fixture to disability-rights activist, from London-art-world lightning rod to the unofficial patron of Margate. Now comes a major retrospective at the Tate Modern, which celebrates Emin in all her contradictions. —Elena Clavarino
