Charles Fried, a former U.S. solicitor general and conservative legal scholar who taught at Harvard Law School for decades, has died, the university said. Fried, who died Tuesday, joined the Harvard faculty in 1961 would go on to teach thousands of students in areas such as First Amendment and contract law. Fried argued many important cases in state and federal courts, according to Harvard, including Daubert v. Merrell Dow Pharmaceuticals, in which the U.S. Supreme Court set standards for allowing scientific expert testimony in federal courts.
