Cloud Gate in Chicago's Millennium Park — the mirrored bean that has eaten the city's selfie-image since 2006 — is only the most photographed of Anish Kapoor's works. The Turner Prize in 1991, the Tate Modern Turbine Hall commission in 2002, the Venice Biennale British representation in 1990, the ArcelorMittal Orbit at the London Olympic Park in 2012. Born in Bombay in 1954 to an Iraqi-Jewish mother and a Punjabi-Hindu father, schooled at the Doon, then in the early 1970s the move to London that defined the rest of his life — Hornsey, then Chelsea, then a half-century of pigment, void, and the politics of public sculpture. The contestation around his commercial control of certain pigments (the famous Vantablack arrangement) and his political positions have produced friction; the work itself remains, by any honest measure, among the most influential sculptural output of the past forty years.
