Background: Atsuko Maeda (Qian Tian  Dun Zi , Maeda Atsuko, born July 10, 1991, in Ichikawa, Chiba) is a Japanese singer and actress known for her work in the Japanese idol group AKB48. Maeda was one of the most prominent members in the group, and placed first among all AKB48 and sister group candidates in the group's general 2009 and 2011 elections, and second in the 2010 election. She also appeared on many of its album covers. On March 25, 2012, she announced her graduation from AKB48; it was held on August 27.
Context: At age 14, Maeda became a member of AKB48's first group, Team A, which composed of 24 girls and debuted on December 8, 2005.  In 2009, Maeda won the first edition of AKB48's annual general elections, which are described as a popularity contest. As a result, she was the headlined performer for the group's 13th single, "Iiwake Maybe". The following year, she placed second overall, but still had a significant choreography position in the lineup for "Heavy Rotation". Later that year, AKB48 employed a rock-paper-scissors tournament to determine the top spot of AKB48's 19th major single "Chance no Junban". Maeda placed 15th, which secured her a spot on title track. Maeda would also win the group's third general election held in 2011.  Maeda was one of the members who sang on every AKB48 title track since the group's inception. Her streak of A-side appearances ended in 2011, when she lost to Team K captain Sayaka Akimoto at a rock-paper-scissors tournament which determined the featured members for the group's 24th single "Ue kara Mariko".  On March 25, 2012, during an AKB48 Concert at the Saitama Super Arena, Maeda announced that she would leave the group. This caused a large buzz in the Japanese news, and spawned a rumor (later proved false) that a student from University of Tokyo had committed suicide over the announcement. AKB48 later announced that Maeda would leave after the Tokyo Dome concerts; For her final performance, there were 229,096 requests filed for seat tickets. Her farewell performance and ceremony occurred on August 27 at the AKB48 theater, and was streamed live on YouTube.

Background: Walter Leland Cronkite Jr. (November 4, 1916 - July 17, 2009) was an American broadcast journalist who served as anchorman for the CBS Evening News for 19 years (1962-1981). During the heyday of CBS News in the 1960s and 1970s, he was often cited as "the most trusted man in America" after being so named in an opinion poll. He reported many events from 1937 to 1981, including bombings in World War II; the Nuremberg trials; combat in the Vietnam War; the Dawson's Field hijackings; Watergate; the Iran Hostage Crisis; and the assassinations of President John F. Kennedy, civil rights pioneer Martin Luther King Jr., and Beatles musician John Lennon. He was also known for his extensive coverage of the U.S. space program, from Project Mercury to the Moon landings to the Space Shuttle.
Context: He dropped out of college in his junior year, in the fall term of 1935, after starting a series of newspaper reporting jobs covering news and sports. He entered broadcasting as a radio announcer for WKY in Oklahoma City, Oklahoma. In 1936, he met his future wife, Mary Elizabeth "Betsy" Maxwell, while working as the sports announcer for KCMO (AM) in Kansas City, Missouri. His broadcast name was "Walter Wilcox". He would explain later that radio stations at the time did not want people to use their real names for fear of taking their listeners with them if they left. In Kansas City, he joined the United Press in 1937. He became one of the top American reporters in World War II, covering battles in North Africa and Europe.  With his name now established, he received a job offer from Edward R. Murrow at CBS News to join the Murrow Boys team of war correspondents, relieving Bill Downs as the head of the Moscow bureau. CBS offered Cronkite $125 a week along with "commercial fees" amounting to $25 for almost every time Cronkite reported on air. Up to that point, he had been making $57.50 per week at UP, but he had reservations about broadcasting. He initially accepted the offer. When he informed his boss Harrison Salisbury, UP countered with a raise of $17.50 per week; Hugh Baillie also offered him an extra $20 per week to stay. Cronkite ultimately accepted the UP offer, a move which angered Murrow and drove a wedge between them that would last for years.  Cronkite was on board USS Texas (BB-35) starting in Norfolk, Virginia, through her service off the coast of North Africa as part of Operation Torch, and thence back to the US. On the return trip, Cronkite was flown off Texas in one of her OS2U Kingfisher aircraft when Norfolk was within flying distance. He was granted permission to be flown the rest of the distance to Norfolk so that he could outpace a rival correspondent on USS Massachusetts (BB-59) to return to the US and to issue the first uncensored news reports to published about Operation Torch. Cronkite's experiences aboard Texas launched his career as a war correspondent. Subsequently, he was one of eight journalists selected by the United States Army Air Forces to fly bombing raids over Germany in a B-17 Flying Fortress part of group called the Writing 69th, and during a mission fired a machine gun at a German fighter. He also landed in a glider with the 101st Airborne in Operation Market Garden and covered the Battle of the Bulge. After the war, he covered the Nuremberg trials and served as the United Press main reporter in Moscow from 1946 to 1948.
