IN: Theodore Roosevelt Jr. ( ROH-z@-velt; October 27, 1858 - January 6, 1919) was an American statesman and writer who served as the 26th President of the United States from 1901 to 1909. He also served as the 25th Vice President of the United States from March to September 1901 and as the 33rd Governor of New York from 1899 to 1900. As a leader of the Republican Party during this time, he became a driving force for the Progressive Era in the United States in the early 20th century. His face is depicted on Mount Rushmore, alongside those of George Washington, Thomas Jefferson, and Abraham Lincoln.

Theodore Roosevelt Jr. was born on October 27, 1858, at East 20th Street in New York City. He was the second of four children born to socialite Martha Stewart "Mittie" Bulloch and businessman and philanthropist Theodore Roosevelt Sr. He had an older sister, Anna (nicknamed "Bamie"), a younger brother, Elliott, and a younger sister, Corinne. Elliott was later the father of First Lady Anna Eleanor Roosevelt, the wife of Theodore's distant cousin, President Franklin Delano Roosevelt. His paternal grandfather was of Dutch descent; his other ancestry included primarily Scottish and Scots-Irish, English and smaller amounts of German, Welsh, and French. Theodore Sr. was the fifth son of businessman Cornelius Van Schaack "C.V.S." Roosevelt and Margaret Barnhill. Theodore's fourth cousin, James Roosevelt I, who was also a businessman, was the father of President Franklin Delano Roosevelt. Mittie was the younger daughter of Major James Stephens Bulloch and Martha P. "Patsy" Stewart. Through the Van Schaacks, Roosevelt was a descendant of the Schuyler family.  Roosevelt's youth was largely shaped by his poor health and debilitating asthma. He repeatedly experienced sudden nighttime asthma attacks that caused the experience of being smothered to death, which terrified both Theodore and his parents. Doctors had no cure. Nevertheless, he was energetic and mischievously inquisitive. His lifelong interest in zoology began at age seven when he saw a dead seal at a local market; after obtaining the seal's head, Roosevelt and two cousins formed what they called the "Roosevelt Museum of Natural History". Having learned the rudiments of taxidermy, he filled his makeshift museum with animals that he killed or caught; he then studied the animals and prepared them for display. At age nine, he recorded his observation of insects in a paper entitled "The Natural History of Insects".  Roosevelt's father significantly influenced him. His father was a prominent leader in New York's cultural affairs; he helped to found the Metropolitan Museum of Art, and had been especially active in mobilizing support for the Union during the Civil War, even though his in-laws included Confederate leaders. Roosevelt said, "My father, Theodore Roosevelt, was the best man I ever knew. He combined strength and courage with gentleness, tenderness, and great unselfishness. He would not tolerate in us children selfishness or cruelty, idleness, cowardice, or untruthfulness." Family trips abroad, including tours of Europe in 1869 and 1870, and Egypt in 1872, shaped his cosmopolitan perspective. Hiking with his family in the Alps in 1869, Roosevelt found that he could keep pace with his father. He had discovered the significant benefits of physical exertion to minimize his asthma and bolster his spirits. Roosevelt began a heavy regime of exercise. After being manhandled by two older boys on a camping trip, he found a boxing coach to teach him to fight and strengthen his body.

input: The orchestra was founded in 1945 by Walter Legge. As Legge was a recording producer for EMI, it was believed that the orchestra was primarily formed for recording purposes, but that was not Legge's intention. He had been Sir Thomas Beecham's assistant at the Royal Opera House, Covent Garden, before World War II, and, assuming that he and Beecham would be in charge there again after the war, Legge planned to establish a first-class orchestra for opera, concerts and recordings. After the war, opera resumed at Covent Garden under a different management, but Legge went ahead with his plans for a new orchestra. His contacts in the musical world during the war enabled him to secure the services of a large number of talented young musicians still serving in the armed forces in 1945. At the Philharmonia's first concert on 25 October 1945, more than sixty per cent of the players were still officially in the services. Beecham conducted the concert (for the fee of one cigar), but as he refused to be Legge's employee and Legge refused to cede control of the orchestra, Beecham instead went on to found the Royal Philharmonic Orchestra.  In its early years, with financial support of the Last Maharaja of Mysore, Jayachamaraja Wodeyar Bahadur (1919-1974), the orchestra engaged many prominent conductors, including Arturo Toscanini, Richard Strauss and Wilhelm Furtwangler. Herbert von Karajan was closely associated with the Philharmonia in its early years, although he never held an official title with the orchestra. At first, Legge was against appointing an official principal conductor, feeling that no one conductor should have more importance to the orchestra than Legge himself. But Karajan was principal conductor in all but name. He built the orchestra into one of the finest in the world and made numerous recordings, including all the Beethoven symphonies.  In 1954, Karajan was elected music director of the Berlin Philharmonic Orchestra and subsequently curtailed his work with the Philharmonia. Needing to find a new conductor for the orchestra, Legge turned to Otto Klemperer, whose career was flagging at the time. Klemperer's name became closely linked with the orchestra during an "Indian summer" of celebrated recordings. In 1959, Klemperer was named music director for life.  On 10 March 1964, Legge announced that he was going to disband the Philharmonia Orchestra. At a recording session with Klemperer, a meeting was convened where those present unanimously agreed that they would not allow the orchestra to be disbanded. Klemperer gave his immediate support. On 17 March 1964, the members of the orchestra elected their own governing body and adopted the name New Philharmonia Orchestra. The inaugural concert of the New Philharmonia under its own auspices took place on 27 October 1964. It was a performance of Beethoven's Symphony No. 9, conducted by Klemperer, who was now honorary president of the orchestra. From 1966 until 1972, the chairman of the orchestra was the principal flautist, Gareth Morris.  The orchestra gave many more live performances after it became self-governing than it had under Legge's management. It reacquired the rights to the name "Philharmonia Orchestra" in 1977, and has been known by that name ever since.
