Holt presented 22 stones, including stones from the homes of American luminaries George Washington, Henry Wadsworth Longfellow, Daniel Webster, Calvin Coolidge, and Ralph Waldo Emerson.[1] Early additions to the Walk of Fame were predominantly American, but later additions would include stones from places associated with internationally famous figures as diverse as St. Augustine, Emperor Humayun, and William Wordsworth. By 1932 the Walk of Fame had over 200 stones,[28] many of which Holt himself had brought back to campus: the Charles Dickens stone he had picked up while visiting Gad's Hill, and he claimed that the Mohammed stone was brought back from Mecca by a student's sister, "at the risk of fine and imprisonment."[3]
