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.
On April 16, 1962, Cronkite succeeded Douglas Edwards as anchorman of the CBS's nightly feature newscast, tentatively renamed Walter Cronkite with the News, but later the CBS Evening News on September 2, 1963, when the show was expanded from 15 to 30 minutes, making Cronkite the anchor of American network television's first nightly half-hour news program. Cronkite's tenure as anchor of the CBS Evening News made him an icon in television news. During the early part of his tenure anchoring the CBS Evening News, Cronkite competed against NBC's anchor team of Chet Huntley and David Brinkley, who anchored the Huntley-Brinkley Report. For much of the 1960s, the Huntley-Brinkley Report had more viewers than Cronkite's broadcast. A key moment for Cronkite came during his coverage of John F. Kennedy's assassination on November 22, 1963. Another factor in Cronkite and CBS' ascendancy to the top of the ratings was that, as the decade progressed, RCA made a corporate decision not to fund NBC News at the levels that CBS provided for its news broadcasts. Consequently, CBS News acquired a reputation for greater accuracy and depth in coverage. This reputation meshed well with Cronkite's wire service experience, and in 1967 the CBS Evening News began to surpass The Huntley-Brinkley Report in viewership during the summer months. In 1969, during the Apollo 11 (with co-host and former astronaut Wally Schirra) and Apollo 13 moon missions, Cronkite received the best ratings and made CBS the most-watched television network for the missions. In 1970, when Huntley retired, the CBS Evening News finally dominated the American TV news viewing audience. Although NBC finally settled on the skilled and well-respected broadcast journalist John Chancellor, Cronkite proved to be more popular and continued to be top-rated until his retirement in 1981. One of Cronkite's trademarks was ending the CBS Evening News with the phrase "...And that's the way it is," followed by the date. Keeping to standards of objective journalism, he omitted this phrase on nights when he ended the newscast with opinion or commentary. Beginning with January 16, 1980, Day 50 of the Iran hostage crisis, Cronkite added the length of the hostages' captivity to the show's closing in order to remind the audience of the unresolved situation, ending only on Day 444, January 20, 1981.

What were his ratings for the Apollo 11 and Apollo 13 missions?

and made CBS the most-watched television network for the missions.

Allan David Bloom (September 14, 1930 - October 7, 1992) was an American philosopher, classicist, and academician. He studied under David Grene, Leo Strauss, Richard McKeon, and Alexandre Kojeve. He subsequently taught at Cornell University, the University of Toronto, Yale University, Ecole Normale Superieure of Paris, and the University of Chicago. Bloom championed the idea of Great Books education and became famous for his criticism of contemporary American higher education, with his views being expressed in his bestselling 1987 book, The Closing of the American Mind.
Allan Bloom was born in Indianapolis, Indiana in 1930 to second-generation Jewish parents who were both social workers. The couple had a daughter, Lucille, two years earlier. As a thirteen-year-old, Bloom read a Readers Digest article about the University of Chicago and told his parents he wanted to attend; his parents thought it was unreasonable and did not encourage his hopes. Yet, when his family moved to Chicago in 1944, his parents met a psychiatrist and family friend whose son was enrolled in the University of Chicago's humanities program for gifted students. In 1946, Bloom was accepted to the same program, starting his degree at the age of fifteen, and spending the next decade of his life enrolled at the University in Chicago's Hyde Park neighborhood. This began his lifelong passion for the 'idea' of the university. In the preface to Giants and Dwarfs: Essays, 1960-1990, he stated that his education "began with Freud and ended with Plato". The theme of this education was self-knowledge, or self-discovery--an idea that Bloom would later write, seemed impossible to conceive of for a Midwestern American boy. He credits Leo Strauss as the teacher who made this endeavor possible for him. Bloom graduated from the University of Chicago with his Bachelor's Degree at the age of 18. One of his college classmates was the classicist Seth Benardete. For post-graduate studies, he enrolled in the University of Chicago's Committee on Social Thought, where he was assigned Classicist David Grene as tutor, and went on to write his thesis on Isocrates. Grene recalled Bloom as an energetic and humorous student completely dedicated to studying classics, but with no definite career ambitions. The Committee was a unique interdisciplinary program that attracted a small number of students due to its rigorous academic requirements and lack of clear employment opportunities after graduation. Bloom earned his Ph.D. from the Committee on Social Thought in 1955. He subsequently studied under the influential Hegelian philosopher Alexandre Kojeve in Paris, whose lectures Bloom would later introduce to the English-speaking world. While teaching philosophy at the Ecole Normale Superieure in Paris, he befriended Raymond Aron, amongst many other philosophers. Among the American expatriate community in Paris his friends included leftist writer Susan Sontag.
