1962 – President John F. Kennedy opened the Seattle World’s Fair by telephone from Palm Beach, Florida. He pressed a gold telegraph key which focused an antenna at Andover, Maine and a Navy radio telescope station in Maryland on a star to pick up a 10,000 year-old radio signal. That in turn set in motion various exhibits at the fair.
