IN: Koch was born in Crotona Park East section of The Bronx borough of New York City, the son of Yetta (or Joyce, nee Silpe) and Louis (Leib) Koch, immigrants from Kozliv and Uscieczko in Eastern Galicia. He came from a family of Conservative Jews who resided in Newark, New Jersey, where his father worked at a theater. As a child, he worked as a hatcheck boy in a Newark dance hall. He graduated from South Side High School in Newark in 1941.

In the years following his mayoralty, Koch became a partner in the law firm of Robinson, Silverman, Pearce, Aronsohn, and Berman LLP, (now Bryan Cave LLP) and became a commentator on politics, as well reviewing movies and restaurants, for newspapers, radio and television. He also became an adjunct professor at New York University (NYU) and was the judge on The People's Court for two years (1997-1999), following the retirement of Judge Joseph Wapner. In 1999, he was a visiting professor at Brandeis University. Koch regularly appeared on the lecture circuit, and had a highly rated local talk show on WABC radio. He also hosted his own movie review video show on the web called The Mayor at the Movies.  On August 12, 1993, a street in southern Tel Aviv was named after Koch in a ceremony attended by him along prominent Israeli and American dignitaries.  In 2004, together with his sister Pat (also Pauline) Koch Thaler, Koch wrote a children's book, Eddie, Harold's Little Brother; the book told the story of Koch's own childhood, when he tried unsuccessfully to emulate his older brother Harold's baseball talents, before realizing that he should instead focus on what he was already good at, which was telling stories and speaking in public.  On March 23, 2011, the New York City Council voted to rename the Queensboro Bridge as the "Ed Koch Queensboro Bridge" in honor of the former mayor. Later, city councilman Peter Vallone (D-Queens) introduced legislation banning the naming of New York City property after people who are still alive. The legislation subsequently failed. In May 2011 Koch sat for a portrait by Dmitry Borshch which has been exhibited at the Institute of Oriental Studies of the Russian Academy of Sciences, DePaul University, Brecht Forum, CUNY Graduate Center and is included in the Catalog of American Portraits, maintained by the Smithsonian's National Portrait Gallery.

Was he involved in any bad things or scandals in his later life?

OUT: 

input: Reasoner took part in covering the John F. Kennedy assassination on Friday, November 22, 1963. Walter Cronkite and Charles Collingwood had been switching back and forth to report on the incident for about four hours after Cronkite initially broke the news at 1:40 p.m. EST. Reasoner took over the anchor chair after Collingwood tossed it to him at 5:49 p.m. EST and opened with the repeat of an announcement by Frank Stanton, the president of CBS, which had already been relayed by Collingwood:  He later reported on the arrival of Kennedy's body in Washington, D.C., and provided details regarding Lee Harvey Oswald (who was then accused only of killing Dallas Police Officer J. D. Tippit; he would be accused of killing the president only hours later). Reasoner left the desk when Cronkite returned to anchor CBS Evening News at 6:35 p.m. EST. He reappeared in another studio, approximately two hours later, to narrate a special program called "John F. Kennedy -- A Man of This Century", and he talked about Kennedy's career and the new president, Lyndon B. Johnson and announced the conclusion of CBS's coverage for that day. (Reasoner also anchored the final coverage of the next day, with a CBS News special titled "A Day to Mourn".)  Reasoner's next appearance came two days later, Sunday, and as Reasoner was at the anchor desk, Oswald was shot by Jack Ruby while being moved in the Dallas City Jail. At that very moment, Roger Mudd was filing a report from Washington, describing the President's funeral arrangements.  At this point, CBS abruptly cut back to Reasoner at the newsroom anchor desk with breaking news.  At the time CBS picked up KRLD's live feed of the city jail basement, Oswald was lying on the floor and Dallas Police were apprehending Ruby. KRLD's reporter on the scene, Bob Huffaker, was heard to say, "Oswald has been shot, Oswald has been shot". After the ambulance carrying Oswald sped out of the jail en route to Parkland Hospital, KRLD switched back to CBS in New York, where Reasoner replayed the tape from the beginning so the viewers could see Ruby shooting Oswald. Several minutes later, he reported that the Dallas Police had released Ruby's name. (Reasoner was not at the anchor desk when Oswald was declared dead since he had been replaced by Cronkite.)
