Question: 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.

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.

Answer: he joined the United Press in 1937.

Problem: Abner Doubleday (June 26, 1819 - January 26, 1893) was a career United States Army officer and Union general in the American Civil War. He fired the first shot in defense of Fort Sumter, the opening battle of the war, and had a pivotal role in the early fighting at the Battle of Gettysburg. Gettysburg was his finest hour, but his relief by Maj. Gen. George G. Meade caused lasting enmity between the two men.

Although Doubleday achieved minor fame as a competent combat general with experience in many important Civil War battles, he is more widely known as the supposed inventor of the game of baseball, in Elihu Phinney's cow pasture in Cooperstown, New York, in 1839.  The Mills Commission, chaired by Abraham G. Mills, the fourth president of the National League, was appointed in 1905 to determine the origin of baseball. The committee's final report, on December 30, 1907, stated, in part, that "the first scheme for playing baseball, according to the best evidence obtainable to date, was devised by Abner Doubleday at Cooperstown, New York, in 1839." It concluded by saying, "in the years to come, in the view of the hundreds of thousands of people who are devoted to baseball, and the millions who will be, Abner Doubleday's fame will rest evenly, if not quite as much, upon the fact that he was its inventor ... as upon his brilliant and distinguished career as an officer in the Federal Army."  However, there is considerable evidence to dispute this claim. Baseball historian George B. Kirsch has described the results of the Mills Commission as a "myth". He wrote, "Robert Henderson, Harold Seymour, and other scholars have since debunked the Doubleday-Cooperstown myth, which nonetheless remains powerful in the American imagination because of the efforts of Major League Baseball and the Hall of Fame in Cooperstown." At his death, Doubleday left many letters and papers, none of which describe baseball or give any suggestion that he considered himself a prominent person in the evolution of the game, and his New York Times obituary did not mention the game at all. Chairman Mills himself, who had been a Civil War colleague of Doubleday and a member of the honor guard for Doubleday's body as it lay in state in New York City, never recalled hearing Doubleday describe his role as the inventor. Doubleday was a cadet at West Point in the year of the alleged invention and his family had moved away from Cooperstown the prior year. Furthermore, the primary testimony to the commission that connected baseball to Doubleday was that of Abner Graves, whose credibility is questionable; a few years later, he shot his wife to death and was committed to an institution for the criminally insane for the rest of his life. Part of the confusion could stem from there being another man by the same name in Cooperstown in 1839.  Despite the lack of solid evidence linking Doubleday to the origins of baseball, Cooperstown, New York became the new home of what is today the National Baseball Hall of Fame and Museum in 1937.  There may have been some relationship to baseball as a national sport and Abner Doubleday. While the modern rules of baseball were formulated in New York during the 1840s, it was the scattering of New Yorkers exposed to these rules throughout the country, that spread not only baseball, but also the "New York Rules", thereby harmonizing the rules, and being a catalyst for its growth. Doubleday was a high-ranking officer, whose duties included seeing to provisions for the US Army fighting throughout the south and border states. For the morale of the men, he is said to have provisioned balls and bats for the men.
