Sinead O’Connor’s Life in Pictures

With her short hair and wide eyes, the Irish singer Sinead O’Connor, who has died at the age of 56, cast a powerful silhouette onstage during her music career. The height of her power came in the late 1980s and early 1990s, including a divisive 1992 appearance on “Saturday Night Live” in which she ripped up a photo of Pope John Paul II to protest sexual abuse in the Roman Catholic Church.

O’Connor told Rolling Stone in 1991 that her record company, Ensign, wanted her to wear high-heel boots and tight jeans and grow her hair out. “I decided that they were so pathetic,” she said, “that I shaved my head.”
