Royall Tyler (born July 18, 1757, Boston—died Aug. 26, 1826, Brattleboro, Vt., U.S.) was a U.S. lawyer, teacher, and dramatist, known as the author of the first American comedy, The Contrast (1787).
After graduating from Harvard University, Tyler served in the U.S. Army and later became a lawyer. A meeting with Thomas Wignell, the star comedian of the American Company, in New York City, led him to write The Contrast, which premiered in 1787 at the John Street Theatre. A light comedy echoing the English playwrights Oliver Goldsmith and Richard Sheridan (especially The School for Scandal), The Contrast contains a Yankee character, the predecessor of many such in years to follow, that brought something native to the stage. His other plays, some no longer extant, did not equal The Contrast.
