THE EYEBROWS HAVE IT

Wallace H. Carothers, an American chemist, inventor and the leader of organic chemistry at DuPont Corporation, receives a patent for a silk substitute fabric called nylon. Carothers was a depressive who for years carried a cyanide capsule on a watch chain in case he wanted to commit suicide, but his genius helped produce other polymers such as neoprene and polyester. He eventually did take cyanide—not in pill form, but dissolved in lemon juice—resulting in his death in late 1937.

In Miami, Florida, Giuseppe Zangara attempts to shoot President-elect Franklin D. Roosevelt, but is restrained by a crowd and, in the course of firing five wild shots, hits five people, including Chicago, Illinois Mayor Anton J. Cermak, who dies of his wounds three weeks later. Zangara is quickly tried and sentenced to eighty years in jail for attempted murder, but is later convicted of murder when Cermak dies. Zangara is sentenced to death and executed in Florida’s electric chair.

Seven people, six of them gangster rivals of Al Capone’s South Side gang, are machine gunned to death in Chicago, Illinois, in an event that would become known as the St. Valentine’s Day Massacre. Because two of the shooters were dressed as police officers, it was initially thought that police might have been responsible, but an investigation soon proved the killings were gang related. The slaughter exceeded anything yet seen in the United States at that time.

A jury in Flemington, New Jersey finds Bruno Hauptmann guilty of the 1932 kidnapping and murder of the Lindbergh baby, the son of Charles Lindbergh. Hauptmann is sentenced to death and executed in 1936. For decades, his widow Anna fights to have his named cleared, claiming that Hauptmann did not commit the crime, and was instead a victim of prosecutorial misconduct, but her claims are ultimately dismissed in 1984 after the U.S. Supreme Court refuses to address the case.
