A retired pediatrician from Pittsburgh who helped create the ‘Mr. Yuk’ poison warning for kids, has died. He was 83. The funeral home handling arrangements says Dr. Richard W. Moriarty died Thursday. He was involved in establishing and developing the Pittsburgh Poison Center, where he had served as director. He has said children in focus groups responded strongly to Mr. Yuk's bright green color and upset face. He said in an interview that: “the Mr. Yuk symbol was designed by kids for kids.” The poison awareness campaign began in 1971.
