Question:
John William Carson (October 23, 1925 - January 23, 2005) was an American television host, comedian, writer, and producer. He is best known as the host of The Tonight Show Starring Johnny Carson (1962-1992). Carson received six Emmy Awards, the Television Academy's 1980 Governor's Award, and a 1985 Peabody Award. He was inducted into the Television Academy Hall of Fame in 1987.
Carson began his broadcasting career in 1950 at WOW radio and television in Omaha, Nebraska. Carson soon hosted a morning television program called The Squirrel's Nest. One of his routines involved interviewing pigeons on the roof of the local courthouse that would report on the political corruption they had seen. Carson supplemented his income by serving as master of ceremonies at local church dinners, attended by some of the same politicians and civic leaders whom he had lampooned on the radio.  The wife of one of the Omaha political figures Carson spoofed owned stock in a radio station in Los Angeles, and in 1951 referred Carson to her brother, who was influential in the emerging television market in southern California. Carson joined CBS-owned Los Angeles television station KNXT. In 1953, comic Red Skelton--a fan of Carson's "cult success" low-budget sketch comedy show, Carson's Cellar (1951 to 1953) on KNXT--asked Carson to join his show as a writer. In 1954, Skelton during rehearsal accidentally knocked himself unconscious an hour before his live show began, and Carson successfully filled in for him. In 1955, Jack Benny invited Carson to appear on one of his programs during the opening and closing segments. Carson imitated Benny and claimed that Benny had copied his gestures. Benny predicted that Carson would have a successful career as a comedian.  Carson hosted several shows besides Carson's Cellar, including the game show Earn Your Vacation (1954) and the CBS variety show The Johnny Carson Show (1955-1956). He was a guest panelist on the original To Tell the Truth starting in 1960, later becoming a regular panelist from 1961 until 1962. After the prime time The Johnny Carson Show failed, he moved to New York City to host Who Do You Trust? (1957-1962), formerly known as Do You Trust Your Wife?. In 1958, he appeared as a guest star in an episode entitled "Do You Trust Your Wife" on NBC's short-lived variety show, The Polly Bergen Show. On Who Do You Trust?, Carson met his future sidekick and straight man, Ed McMahon. Although he believed moving to daytime would hurt his career, Who Do You Trust? was a success. It was the first show where he could ad lib and interview guests, and because of Carson's on-camera wit, the show became "the hottest item on daytime television" during his five years at ABC.

Question:
Leonard Bernstein ( BURN-styne; August 25, 1918 - October 14, 1990) was an American composer, conductor, author, music lecturer, and pianist. He was among the first conductors born and educated in the US to receive worldwide acclaim. According to music critic Donal Henahan, he was "one of the most prodigiously talented and successful musicians in American history."
While Bernstein was very well known for his music compositions and conducting, he was also known for his outspoken political views and his strong desire to further social change. His first aspirations for social change were made apparent in his producing (as a student) a recently banned opera, The Cradle Will Rock, by Marc Blitzstein, about the disparity between the working and upper class. His first opera, Trouble in Tahiti, was dedicated to Blitzstein and has a strong social theme, criticizing American civilization and suburban upper-class life in particular. As he went on in his career Bernstein would go on to fight for everything from the influences of "American Music" to the disarming of western nuclear weapons.  Like many of his friends and colleagues, Bernstein had been involved in various left wing causes and organizations since the 1940s. He was blacklisted by the US State Department and CBS in the early 1950s, but unlike others his career was not greatly affected, and he was never required to testify before the House Un-American Activities Committee. His political life received substantial press coverage though in 1970, due to a gathering hosted at his Manhattan apartment on January 14, 1970. Bernstein and his wife held the event seeking to raise awareness and money for the defense of several members of the Black Panther Party against a variety of charges. The New York Times initially covered the gathering as a lifestyle item, but later posted an editorial harshly unfavorable to Bernstein following generally negative reaction to the widely publicized story. This reaction culminated in June 1970 with the appearance of "Radical Chic: That Party at Lenny's", an essay by satirist Tom Wolfe featured on the cover of the magazine New York. The article contrasted the Bernsteins' comfortable lifestyle in one of the world's most expensive neighborhoods with the anti-establishment politics of the Black Panthers. It led to the popularization of "radical chic" as a critical term. Both Bernstein and his wife Felicia responded to the criticism, arguing that they were motivated not by a shallow desire to express fashionable sympathy but by their concern for civil liberties.  Bernstein was named in the book Red Channels: The Report of Communist Influence in Radio and Television (1950) as a Communist along with Aaron Copland, Lena Horne, Pete Seeger, Artie Shaw and other prominent figures of the performing arts. Red Channels was issued by the right-wing journal Counterattack and was edited by Vincent Hartnett, who was later found to have libeled and defamed the noted radio personality John Henry Faulk.
