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.
