Ben Hecht  (February 28, 1894 - April 18, 1964) was an American screenwriter, director, producer, playwright, journalist, and novelist. A journalist in his youth, he went on to write thirty-five books and some of the most entertaining screenplays and plays in America. He received screen credits, alone or in collaboration, for the stories or screenplays of some seventy films. At the age of 16, Hecht ran away to Chicago, where, in his own words, he "haunted streets, whorehouses, police stations, courtrooms, theater stages, jails, saloons, slums, madhouses, fires, murders, riots, banquet halls, and bookshops".

Hecht was born in New York City, the son of Russian Jewish immigrants. His father, Joseph Hecht, worked in the garment industry. His father and mother, Sarah Swernofsky Hecht, had immigrated to New York from Minsk, Belarus. The Hechts married in 1892.  The family moved to Racine, Wisconsin, where Ben attended high school. When Hecht was in his early teens, he would spend the summers with an uncle in Chicago. On the road much of the time, his father did not have much effect on Hecht's childhood, and his mother was busy managing the store outlet in downtown Racine. Film author Scott Siegal wrote, "He was considered a child prodigy at age ten, seemingly on his way to a career as a concert violinist, but two years later was performing as a circus acrobat."  After graduating from Racine High School in 1910, at age sixteen Hecht moved to Chicago, running away to live there permanently. He lived with relatives, and started a career in journalism. He found work as a reporter, first for the Chicago Journal, and later with the Chicago Daily News. He was an excellent reporter who worked on several Chicago papers. After World War I, Hecht was sent to cover Berlin for the Daily News. There he wrote his first and most successful novel, Erik Dorn (1921). It was a sensational debut for Hecht as a serious writer.  The 1969 movie, Gaily, Gaily, directed by Norman Jewison and starring Beau Bridges as "Ben Harvey", was based on Hecht's life during his early years working as a reporter in Chicago. The film was nominated for three Oscars. The story was taken from a portion of his autobiography, A Child of the Century. Answer this question using a quote from the following article:
