JOHN H. CLARKE was born in Lisbon, Ohio, on September 18, 1857. Following graduation from Western Reserve College in 1877, he was tutored in law by his father and was admitted to the bar in 1878. After practicing law with his father’s law firm for two years, Clarke moved to Youngstown, Ohio, and established his own practice, specializing in corporate law. He also acquired an ownership in the local newspaper, which was known for its support of progressive reform. He ran for the United States Senate in 1894 but was defeated by the incumbent. In 1897, Clarke left his practice in Youngstown to join a Cleveland law firm. Clarke had been a practicing attorney for thirty-five years when President Woodrow Wilson appointed him in 1914 to the United States District Court for the Northern District of Ohio, where he served for two years. On July 14, 1916, President Wilson appointed Clarke to the Supreme Court of the United States, and the Senate confirmed the appointment on July 24, 1916. Clarke resigned from the Supreme Court on September 18, 1922, to promote American participation in the League of Nations. He died on March 22, 1945, at the age of eighty-seven.
