Ada Alice Green Wright (born 1874)

In 1874, in the year that Ada Alice Green Wright was born, on May 20th, Levi Strauss and Jacob Davis were approved for a patent for "blue jeans with copper rivets". They charged $13.50 per dozen jeans. Although the term "jeans" was first used in 1795 - in Italy - using rivets to reinforce stress points in jeans such as pockets and the bottom of the fly was an original idea..

In 1910, Halley's comet, which returns past the earth every 75 - 76 years was observed photographically for the first time. Two fortuitous events occurred - photography had been invented since the last time the comet had passed and the comet was relatively close. There was panic because one astronomer claimed that the gas from its tail "would impregnate the atmosphere and possibly snuff out all life on the planet." People bought gas masks, "anti-comet pills" and "anti-comet umbrellas".

In 1921, on November 11th, the first burial was held at the Tomb of the Unknown Soldier in Arlington National Cemetery. The body of an unknown soldier - selected by Army Sgt. Edward F. Younger who was highly decorated for valor and received the Distinguished Service Cross in "The Great War" - was brought back from France (World War 1) and placed in the newly completed tomb. President Warren G. Harding officiated at the interment ceremonies.

In 1937, on May 6th, the German zeppelin the Hindenburg caught fire and blew up. The Hindenburg was a passenger ship traveling to Frankfurt Germany. It tried to dock in New Jersey, one of the stops, and something went wrong - it blew up. Thirty-six people were killed out of the 97 on board - 13 passengers, 22 crewmen, and one ground worker. The reasons for the explosion are still disputed.

In 1940, on July 27th, the cartoon character Bugs Bunny debuted in his first film A Wild Hare - voiced by Mel Blanc. He has since appeared in more short films, feature films, compilations, TV series, music records, comic books, video games, award shows, amusement park rides, and commercials than any other cartoon character. He even has a star on the Hollywood Walk of Fame. "What's up, Doc?"
