Bertha Heidke (born 1909)

In 1909, in the year that Bertha Heidke was born, explorer Robert Peary, a Rear Admiral in the U.S. Navy, claimed to have been the first to have reached the geographic North Pole. His claim has been disputed for over a century - some say that he ended up 60 miles from the North Pole. Peary was the only navigator on his team and he didn't submit his records for public review.

In 1930, as head of the Motion Picture Producers and Distributors of America, William Hays established a code of decency that outlined what was acceptable in films. The public - and government - had felt that films in the '20's had become increasingly risque and that the behavior of its stars was becoming scandalous. Laws were being passed. In response, the heads of the movie studios adopted a voluntary "code", hoping to head off legislation. The first part of the code prohibited "lowering the moral standards of those who see it", called for depictions of the "correct standards of life", and forbade a picture from showing any sort of ridicule towards a law or "creating sympathy for its violation". The second part dealt with particular behavior in film such as homosexuality, the use of specific curse words, and miscegenation.

In 1957, on September 24th, the "Little Rock Nine" (nine African-American students) entered Little Rock High School. Arkansas Gov. Orval Faubus had previously prevented the students from entering the school at the beginning of the term with the Arkansas National Guard - they blocked the door. President Eisenhower ordered federal troops - the 101st Airborne Division of the United States Army - to guard the students and allow them entry.

In 1972, on June 17th, 5 men were arrested by police in an attempt to bug the Democratic National Committee headquarters in Washington D.C.’s Watergate hotel. The burglars were found to be paid by cash from a slush fund used by the Committee for the Re-Election of the President - the official organization of President Nixon's campaign.

In 1980, on December 8th, ex-Beatle John Lennon was shot and killed by Mark David Chapman in front of his home - the Dakota - in New York City. Chapman was found guilty of murder and still remains in jail.
