Walter Leland Cronkite, Jr. was an American broadcast journalist, best known as anchorman for the CBS Evening News for 19 years. 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; Watergate; the Iran Hostage Crisis; and the murders 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 was the only non-NASA recipient of a Moon-rock award. Cronkite is well known for his departing catchphrase "And that's the way it is," followed by the date on which the appearance aired.
