Charles Eliot Norton was an American author, social critic, and Harvard professor of art based in New England. He was a progressive social reformer and a liberal activist whom many of his contemporaries considered the most cultivated man in the United States. He was from the same notable Eliot family as the 20th-century poet T. S. Eliot, who made his career in the United Kingdom. Wikipedia
