The only naturalized American to serve on the U.S. Supreme Court, Felix Frankfurter (1882-1965), immigrated from Austria to New York in 1894. He graduated from Harvard Law School in 1906, and later joined the school’s faculty. Throughout the 1920s, Frankfurter was influential both as a law professor and as a participant in public debates. He became a trusted advisor to President Franklin D. Roosevelt, resulting in his nomination to the Supreme Court in 1939. While Frankfurter argued in favor of the regulations established by the New Deal, his perceived unwillingness to protect minorities and monitor the fairness of the political process left him at odds with other justices.
