I don't think the Queen Mum was 'notorious' - certainly very notable, but mostly in a favourable way!One better goes into show business to become a centennial. I recall Bob Hope, George Burns, Olivia de Havilland, Hall Roach, Kirk Douglas, Irving Berlin, Vera Lynn and Leni Riefenstahl to name a few.
Not really 'world leaders', but notoriuos were Queen Mother Elizabeth and Joao Havelange.
