It is 3:20 p.m. on June 26, 1963. A crowd of nearly 20,000 gathers on the campus of Freie Universität, in Berlin’s Dahlem district. They have come to hear the man who is driving up to the Henry Ford Building right now, in a Lincoln Continental convertible with Washington license plates. And they won’t be disappointed: A few minutes later, President John F. Kennedy starts his historic speech at Freie Universität Berlin.
