Stwart Cameron (born 1888)

In 1888, in the year that Stwart Cameron was born, on August 7th, the body of a prostitute was found in the Whitechapel section of London. Martha Tabram had been stabbed 39 times - a possible but not confirmed victim of Jack the Ripper. On August 31st, the body of Mary Ann Nichols was found - stabbed and mutilated. On September 8th, the body of Annie Chapman was found - throat slit and disemboweled. On September 30th, Elizabeth Stride, also a prostitute in Whitechapel, was found dead from a slit throat. Within an hour, another body was discovered - Catherine Eddowes'. She was far more savagely murdered and it is thought that the Ripper had more time with her. Then, on November 9th, the body of prostitute Mary Jane Kelly was found in a boarding room in Whitechapel. Considered to be the probable fifth, and last, of Jack the Ripper's victims, Kelly's was the most savage of his murders.

In 1899, the meaning of Chinese "oracle bones" was rediscovered. Farmers in China had been turning up the bones in their fields for generations but most often they were ground up and sold as medicine. The chancellor of the Imperial Academy and a friend noticed, before they ground the bones, that they had writing. The bones had been used around the second millennium BC for divination.

In 1952, on July 2, Dr. Jonas E. Salk tested the first dead-virus polio vaccine on 43 children. The worst epidemic of polio had broken out that year - in the U.S. there were 58,000 cases reported. Of these, 3,145 people had died and 21,269 were left with mild to disabling paralysis.

In 1986, on January 28th, the space shuttle Challenger exploded 73 seconds after launch. All seven crew members died. The cause of the explosion was later found to be a failed O-ring. The O-ring failure was due to the unusually cold conditions at Cape Canaveral.

In 1997, on August 31st, Princess Diana of Great Britain was killed when her car crashed into a pillar in the tunnel under the Pont de l'Alma bridge in Paris. The car she was riding in was trying to evade the paparazzi but it was also discovered later that the driver of the car, who was also killed, had three times the legal limit of alcohol which likely contributed to the accident.
