Mel Brooks (born Melvin Kaminsky; June 28, 1926) is an American actor, writer, producer, director, comedian, and composer. He is known as a creator of broad film farces and comic parodies. Brooks began his career as a comic and a writer for the early TV variety show Your Show of Shows. He created, with Buck Henry, the hit television comedy series Get Smart, which ran from 1965 to 1970.
For several years, Brooks had been toying with a bizarre and unconventional idea about a musical comedy of Adolf Hitler. Brooks explored the idea as a novel and a play before finally writing a script. Eventually, he was able to find two producers to fund the show, Joseph E. Levine and Sidney Glazier, and made his first feature film, The Producers, in 1967. The Producers was so brazen in its satire that major studios would not touch it, nor would many exhibitors. Brooks finally found an independent distributor who released it as an art film, a specialized attraction. In 1968, Brooks received an Oscar for Best Original Screenplay for the film, beating such writers as Stanley Kubrick and John Cassavetes. The Producers became a smash underground hit, first on the nationwide college circuit, then in revivals and on home video. Brooks later turned it into a musical, which became hugely successful on Broadway, receiving an unprecedented twelve Tony awards. With the moderate financial success of the film The Producers, Glazier financed Brooks' next film in 1970, The Twelve Chairs. Loosely based on a Russian 1928 novel The Twelve Chairs by Ilf and Petrov about greedy materialism in post-revolutionary Russia, the film stars Ron Moody, Frank Langella, and Dom DeLuise as three men individually searching for a fortune in diamonds hidden in a set of 12 antique chairs. Brooks makes a cameo appearance as an alcoholic ex-serf who "yearns for the regular beatings of yesteryear." The film was shot in Yugoslavia with a budget of $1.5 million. The film received poor reviews and was not financially successful.

What did he do after that?

Answer the question at the end by quoting:

Gurney was born on November 1, 1930 in Buffalo, New York to Albert Ramsdell Gurney, Sr. (1896-1977), who was president of Gurney, Becker and Bourne, an insurance and real estate company in Buffalo, and Marion Spaulding (1908-2001). His parents had three children, of which Gurney was the middle: (1) Evelyn Gurney Miller (b. 1929), (2) Albert Ramsdell Gurney, Jr. (b. 1930), and (3) Stephen S. Gurney (b. 1933).
Gurney's plays often explore the theme of declining upper-class "WASP" (White Anglo-Saxon Protestant) life in contemporary America. The Wall Street Journal has called his works "penetratingly witty studies of the WASP ascendancy in retreat." Several of his works are loosely based on his patrician upbringing, including The Cocktail Hour and Indian Blood. The New York Times drama critic Frank Rich, in his review of The Dining Room, wrote, "As a chronicler of contemporary America's most unfashionable social stratum -- upper-middle-class WASPs, this playwright has no current theatrical peer." In his 1988 play, "The Cocktail Hour", the lead character tells her playwright son that theater critics "don't like us.... They resent us. They think we're all Republicans, all superficial and all alcoholics. Only the latter is true." The New York Times described the play as witty observations about a nearly extinct patrician class that regards psychiatry as an affront to good manners, underpaid hired help as a birthright. In a 1989 interview with the New York Times, Gurney said, "Just as it's mentioned in The Cocktail Hour,' my great-grandfather hung up his clothes one day and walked into the Niagara River and no one understood why." Gurney added that "he was a distinguished man in Buffalo. My father could never mention it, and it affected the family well into the fourth generation as a dark and unexplainable gesture. It made my father and his father desperate to be accepted, to be conventional, and comfortable. It made them commit themselves to an ostensibly easy bourgeois world. They saw it so precariously, but the reason was never mentioned. I first learned about it after my father died." Gurney told the Washington Post in 1982: WASPs do have a culture -- traditions, idiosyncrasies, quirks, particular signals and totems we pass on to one another. But the WASP culture, or at least that aspect of the culture I talk about, is enough in the past so that we can now look at it with some objectivity, smile at it, and even appreciate some of its values. There was a closeness of family, a commitment to duty, to stoic responsibility, which I think we have to say weren't entirely bad."
