Marvin Neil Simon (born July 4, 1927) is an American playwright and screenwriter. He is one of the most reliable hitmakers in Broadway history, as well as one of the most performed playwrights in the world. Though primarily a comic writer, some of his plays, particularly the Eugene Trilogy and The Sunshine Boys, reflect on the twentieth century Jewish-American experience.

Simon was born in The Bronx, New York City to Irving and Mamie Simon where after attending De Witt Clinton High School, he briefly attended New York University from 1944 to 1945 and the University of Denver from 1945 to 1946. Two years later, he quit his job as a mailroom clerk in the Warner Brothers offices in Manhattan to write radio and television scripts with his brother Danny Simon, including a tutelage under radio comedy legend Goodman Ace when Ace ran a short-lived writing workshop for CBS. Their revues for Camp Tamiment in Pennsylvania in the early 1950s caught the attention of Sid Caesar, who hired the duo for his popular TV comedy series Your Show of Shows. Simon later incorporated their experiences into his play Laughter on the 23rd Floor. His work won him two Emmy Award nominations and the appreciation of Phil Silvers, who hired him to write for his sitcom in 1959.

In 1961, Simon's first Broadway play, Come Blow Your Horn, opened at the Brooks Atkinson Theatre, where it ran for 678 performances. Six weeks after its closing, his second production, the musical Little Me opened to mixed reviews. Although it failed to attract a large audience, it earned Simon his first Tony Award nomination. Overall, he has garnered seventeen Tony nominations and won three. He also won the 1991 Pulitzer Prize for Drama for Lost In Yonkers.
