In 1914, in the year that Frank W Heidke was born, in August, the world's first red and green traffic lights were installed at the corner of East 105th Street and Euclid Avenue in Cleveland Ohio. The electric traffic light had been invented by a policeman in Salt Lake City Utah in 1912.

In 1923, on August 2, President Warren G. Harding died in office, apparently of a heart attack. He was staying at the Palace Hotel in San Francisco after completing a nationwide tour. Suffering from cramps, indigestion, a fever and shortness of breath, his doctor thought he had food poisoning. After several days of being ill, he suddenly shuddered, slumped over, and died. There were rumors of foul play (some thought that his wife had poisoned him because of his affairs) but no evidence has ever been found.

In 1966, on September 8th, the first Star Trek episode, "The Man Trap," was broadcast on NBC. The plot concerned a creature that sucked salt from human bodies. The original series only aired for 3 seasons due to low ratings.

In 1988, on December 21st, Pan Am Flight 103 exploded over Lockerbie Scotland. The explosion killed all 259 people on board and another 11 on the ground.

After an exhaustive (and long) investigation it came to be believed that two individuals from Libya had planted the bomb.
