The annual celebration of Founder's Day at the Carnegie Institute has become one of the most notable platform occasions in America, made so by the illustrious men who participate in the exercises. Some of these distinguished orators are William McKinley and Grover Cleveland, former Presidents of the United States; John Morley and James Bryce, foremost among British statesmen and authors; Joseph Jefferson, a beloved actor; Richard Watson Gilder, editor and poet; Wu Ting Fang, Chinese diplomat, and Whitelaw Reid, editor and ambassador.
