On this day in 1951, a homemade device explodes at Grand Central Station in New York City, startling commuters but injuring no one. In the next few months, five more bombs were found at landmark sites around New York, including the public library. Authorities realized that this new wave of terrorist acts was the work of the Mad Bomber.
New York's first experience with the so-called Mad Bomber was on November 16, 1940, when a pipe bomb was left in the Edison building with a note that read, "Con Edison crooks, this is for you." More bombs were recovered in 1941, each more powerful than the last, until the Mad Bomber sent a note in December stating, "I will make no more bomb units for the duration of the war." He went on to say that Con Edison, New York's electric utility company, would be brought to justice in due time.
The patriotic Mad Bomber made good on his promise, although he did periodically send threatening notes to the press. After his flurry of activity in 1951, the Mad Bomber was silent until a bomb went off at Radio City Music Hall in 1954. In 1955, the Mad Bomber hit Grand Central Station, Macy's, the RCA building and the Staten Island Ferry.
The police had no luck finding the Mad Bomber, but an investigative team working for Con Ed finally tracked him down. Looking through their employment records, they found that George Peter Metesky had been a disgruntled ex-employee since an accident in 1931. Metesky was enraged that Con Ed refused to pay disability benefits and resorted to terrorism as his revenge. Metesky, a rather mild-mannered man, was found living with his sisters in Connecticut. He was sent to a mental institution in April 1957 where he stayed until his release in 1973.
