Some context: Richard Milhous Nixon was born on January 9, 1913 in Yorba Linda, California, in a house that was built by his father. His parents were Hannah (Milhous) Nixon and Francis A. Nixon. His mother was a Quaker, and his father converted from Methodism to the Quaker faith. Nixon was a descendant of the early American settler, Thomas Cornell, who was also an ancestor of Ezra Cornell, the founder of Cornell University, as well as of Jimmy Carter and Bill Gates.
Nixon laid the groundwork for his overture to China before he became president, writing in Foreign Affairs a year before his election: "There is no place on this small planet for a billion of its potentially most able people to live in angry isolation." Assisting him in this venture was his National Security Advisor and future Secretary of State, Henry Kissinger, with whom the President worked closely, bypassing Cabinet officials. With relations between the Soviet Union and China at a nadir--border clashes between the two took place during Nixon's first year in office--Nixon sent private word to the Chinese that he desired closer relations. A breakthrough came in early 1971, when Chairman Mao invited a team of American table tennis players to visit China and play against top Chinese players. Nixon followed up by sending Kissinger to China for clandestine meetings with Chinese officials. On July 15, 1971, it was simultaneously announced by Beijing and by Nixon (on television and radio) that the President would visit China the following February. The announcements astounded the world. The secrecy allowed both sets of leaders time to prepare the political climate in their countries for the contact.  In February 1972, Nixon and his wife traveled to China. Kissinger briefed Nixon for over 40 hours in preparation. Upon touching down, the President and First Lady emerged from Air Force One and greeted Chinese Premier Zhou Enlai. Nixon made a point of shaking Zhou's hand, something which then-Secretary of State John Foster Dulles had refused to do in 1954 when the two met in Geneva. Over 100 television journalists accompanied the president. On Nixon's orders, television was strongly favored over printed publications, as Nixon felt that the medium would capture the visit much better than print. It also gave him the opportunity to snub the print journalists he despised.  Nixon and Kissinger met for an hour with Mao and Zhou at Mao's official private residence, where they discussed a range of issues. Mao later told his doctor that he had been impressed by Nixon, whom he considered forthright, unlike the leftists and the Soviets. He said he was suspicious of Kissinger, though the National Security Advisor referred to their meeting as his "encounter with history". A formal banquet welcoming the presidential party was given that evening in the Great Hall of the People. The following day, Nixon met with Zhou; the joint communique following this meeting recognized Taiwan as a part of China, and looked forward to a peaceful solution to the problem of reunification. When not in meetings, Nixon toured architectural wonders including the Forbidden City, Ming Tombs, and the Great Wall. Americans received their first glimpse into Chinese life through the cameras which accompanied Pat Nixon, who toured the city of Beijing and visited communes, schools, factories, and hospitals.  The visit ushered in a new era of Sino-American relations. Fearing the possibility of a Sino-American alliance, the Soviet Union yielded to pressure for detente with the United States.

Some context: 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.
