John Paul Stevens, a moderate Republican and former antitrust lawyer from Chicago who evolved into a savvy and sometimes passionate leader of the Supreme Court’s liberal wing and became the third-longest-serving justice on the court before he retired in 2010, died July 16 at a hospital in Fort Lauderdale, Fla. He was 99.
