Queen Elizabeth II celebrates her 96th birthday today. Born in 1926, Karsh first photographed her as Princess in 1943, and again in 1951; those 1951 portraits show the young Princess happy and relaxed, only six months before the death of her father, King George VI, when she suddenly became the future Queen of England. Karsh would go on to make official portraits of the royal family three more times: in 1966, 1984, and 1987.
