<P> During the 1947 royal tour of South Africa, Elizabeth's serene public behaviour was broken, exceptionally, when she rose from the royal car to strike an admirer with her umbrella because she had mistaken his enthusiasm for hostility . The 1948 royal tour of Australia and New Zealand was postponed because of the King's declining health . In March 1949, he had a successful operation to improve the circulation in his right leg . In summer 1951, Queen Elizabeth and her daughters fulfilled the King's public engagements in his place . In September, he was diagnosed with lung cancer . After a lung resection, he appeared to recover, but the delayed trip to Australia and New Zealand was altered so that Princess Elizabeth and her husband, the Duke of Edinburgh, went in the King and Queen's place, in January 1952 . The King died in his sleep on 6 February 1952 while Princess Elizabeth and the Duke of Edinburgh were in Kenya en route to the southern hemisphere, and they returned immediately to London, as queen and prince consort . </P> <P> Shortly after George VI's death, Elizabeth began to be styled as Her Majesty Queen Elizabeth The Queen Mother because the normal style for the widow of a king, "Queen Elizabeth", would have been too similar to the style of her elder daughter, now Queen Elizabeth II . Popularly, she became the "Queen Mother" or the "Queen Mum". </P> <P> She was devastated by her husband's death and retired to Scotland . However, after a meeting with the Prime Minister, Winston Churchill, she broke her retirement and resumed her public duties . Eventually she became just as busy as queen mother as she had been as queen consort . In July 1953, she undertook her first overseas visit since the funeral when she visited the Federation of Rhodesia and Nyasaland with Princess Margaret . She laid the foundation stone of the University College of Rhodesia and Nyasaland--the current University of Zimbabwe . </P> <P> Upon her return to the region in 1957, she was inaugurated as the College's President, and attended other events that were deliberately designed to be multi-racial . During her daughter's extensive tour of the Commonwealth over 1953--54, Elizabeth acted as a Counsellor of State and looked after her grandchildren, Charles and Anne . </P>
