MARILYN MONROE - PART 2 - In 1954, Marilyn Monroe was on top of the world. Films like "Niagara," "Gentlemen Prefer Blondes" and "How to Marry a Millionaire" made her one of Hollywood's most popular actresses. RUPERT MURDOCH - Receiving a humanitarian award from actor Nicole Kidman in 2005, Rupert Murdoch showed no sign of the ruthless business sense that has made him one of the world's most powerful men. THE BEATLES - When John, Paul, George and Ringo arrived at New York's Kennedy Airport in February 1964, they were met by 3,000 screaming teenagers. Beatlemania had officially crossed the Atlantic. SIMONE DE BEAUVOIR - It is often said that behind every great man is a great woman. With Jean-Paul Sartre and Simone de Beauvoir, however, it was one of the few happy times when the great woman did not languish in her famous partner's shadow, but was equally lauded in her own right. MARGARET THATCHER - PART 1 - Her political opponents sneered at Margaret Thatcher for being a grocer's daughter, but as well as owning a grocery shop, her father, Alf Roberts, was active in local politics. His daughter followed her father's example and impressed conservative party officials with her articulate and persuasive manner.
