TIM MAGUIRE: June 26, 1963, during the Cold War, President John F. Kennedy visits what's then West Berlin, showing solidarity with its citizens against communism.
JOHN F. KENNEDY: As a free man, I take pride in the words "Ich bin ein Berliner."
TIM MAGUIRE: The visit takes place exactly 15 years after the start of an American-led airlift to West Berlin aimed at breaking a Soviet blockade. 1945, in San Francisco, 50 countries signed the United Nations Charter, the governing blueprint for the international organization formed after World War II.
2000, after a decade of work, rival scientific teams complete the first rough map of the human genetic code. Michael Morgan is with the Wellcome Trust Genome Campus.
MICHAEL MORGAN: We all are related very, very closely to one another. There are more differences in an ethnic group than there are between ethnic groups, at least at the level of DNA.
TIM MAGUIRE: 1870, in New Jersey, the first section of Atlantic City's famed Boardwalk, running about a mile long, opens to the public.
And 1925, Charlie Chaplin's "The Gold Rush," a silver-screen comic masterpiece, premieres in Hollywood. Today in history, June 26, Tim Maguire, the Associated Press.
