 U.S. President William H. Taft made three nominations to the U.S. Supreme Court on the same day, proposing Edward D. White for Chief Justice, and Joseph R. Lamar and Willis Van Devanter as associate justices. White, an associate justice since 1894, was confirmed as Chief Justice "within less than an hour after his name was sent in", but "The speed with which the confirmation ... was accomplished surprised even staid old senators." Actors and actresses in silent films were regularly using profane and indecent expressions, perceptible only to lipreaders, according to a deaf education teacher who filed a complaint with the film censorship bureau in Cleveland. Mrs. Elmer E. Bates brought the matter to national attention after taking a Cleveland newspaper reporter on a tour of the city's theaters. The reporter, in turn, wrote down what she said that the actors were actually saying, "and at times the language was so vile that she had to stop". Perfume heiress Dorothy Arnold left her parents' apartment in Manhattan to go shopping. After leaving a book shop, the 25-year-old was never seen or heard from again. Her family waited until January 26 to allow police to make the case public, for fear that their daughter's disappearance would lead to a major societal scandal. Her father spent the rest of his life searching for his daughter, spending at least $100,000 on the case before his death in 1922. Numerous false sightings appeared for decades thereafter, as late as 1935 when she would have been 51, but no conclusive evidence was ever proven as to her fate. December 13, 1910 (Tuesday)

"A horrified guest reported to the manager that a woman was smoking in public," wrote the Washington Post, and the manager broke with the custom, adding "I certainly should much prefer to see a woman smoking than drinking a cocktail." Bands of Bedouin warriors attacked and massacred Turkish officers at several military outposts. Born: John H.

 Aviator Henry Farman set an airplane endurance record by remaining in the air for 8 hours and 13 minutes, while flying above the Étampes airfield in France. The previous record had been 6 hours, set by Maurice Tabuteau on October 28. Flight magazine reported the event as taking place on Saturday, December 17. The New York Times Magazine reported that "The aeroplane and automobile have caused a new disease," citing reports from English physicians that "when men pass rapidly through the air, the pressure on the face from fast driving prevents the expulsion of poisoned air from the lungs. The carbonic acid gas is forced back into the body. Only a little of it can get away, because of the air pressing on the face. The gas is rebreathed and poisons the system." The suggested remedy was "a mouthpiece to be strapped to the face with tubes extending from it on either side to the back of the head". December 19, 1910 (Monday)
At the conclusion of voting in British parliamentary elections, the coalition government increased its majority. Of the 660 seats contested, the Conservatives had a plurality (272, compared to the Liberals 271), but Prime Minister Asquith formed a coalition of Liberals, Irish nationalists and Labour MPs for a total of 398. Harold St Maur defeated Henry Duke in the race for the Exeter constituency by four votes (4,786 to 4,782) but the result would be reversed on a recount on April 11, 1911, with the invalidation of 15 ballots a finding that Duke had won by a single vote, 4,777 to 4,776.

At a factory on Bodine Street in Philadelphia, a fire killed 14 men and injured 40 others. December 22, 1910 (Thursday)

Robin, had diverted hundreds of thousands of dollars for his own speculation in the stock market. Washington Savings Bank (New York) and Carnegie Trust Company, also operated by Robin, were closed two days later. Biographer Thomas G. Riggio concluded that Robin was the inspiration for the protagonist in Theodore Dreiser's story "Vanity, Vanity" and for the character of Jay Gatsby in F. Scott Fitzgerald's novel The Great Gatsby. Died: Green McCurtain, 62, principal chief of the Choctaw Nation of Oklahoma since 1902

 At the northern Korean city of Sonchon, a meeting between the Japanese Governor-General (Terauchi Masatake) and the foremost American Christian missionary (George M. McCune) was the occasion of a failed attempt to assassinate Terauchi. The Korean independence group Shinminhoe (New People's Association) was implicated, and Japan accused the missionary group of conspiracy. Hundreds of Koreans and foreign missionaries were arrested and held for more than two years. A group of 105 Koreans were convicted of treason and sentenced to hard labor. The incident, also called the "Christian Conspiracy Case", is referred to in Korean history as Paego-in sakkon, the 105-Man Incident.

 A nova (later referred to as DI Lacertae), was spotted in the constellation Lacerta, by Anglican minister and astronomer T.H.E.C. Espin, who was the first human to see the birth of the new star. With an estimated average distance of 1,569 parsecs (5,117 light years, plus or minus as much as 166 light years), DI Lacertae had exploded sometime before the year 3040 BC and its light took 50 centuries to be seen from Earth. Cornell University Professor Walter F. Willcox delivered his address, "The Change in the Proportion of Children in the United States and the Birth-Rate in France During the Nineteenth Century", to a meeting of the American Statistical Association in St. Louis. Citing the steady decline in the birth rate in the United States since 1870, Willcox said that, statistically speaking, if the trend continued, births would cease by 2015. Though recognized as hyperbole, the address made front-page news as a talking point about what Theodore Roosevelt had described as "race suicide" (for the White race). Born: Paul Bowles, American author; in Jamaica, Queens, New York City (d. 1999)

December 31, 1910 (Saturday)

Hours later, Archibald Hoxsey was told of Moisant's death before attempting a new altitude record in Los Angeles, and said to reporters, "From what I hear, Moisant was careless ... it is too bad, but accidents are liable to happen to all of us." After flying to an altitude of about 7,000 feet, Hoxsey was at 800 feet when his plane suddenly plunged to the ground. Died: Marion Hedgepeth, 53, American outlaw, was shot and killed during an attempted robbery of a saloon in Chicago. References
