Robert Greene (8 July 1558 - 3 September 1592) is sometimes considered to have been the first professional author in England. Greene published in many genres including romances, plays and autobiography. He is now best known for his mysterious double-edged connection to the then-up-and-coming William Shakespeare. Greene's final pamphlet Groats-Worth of Wit describes Shakespeare in very disparaging terms, and Shakespeare scholars have long puzzled over the reason for this hostility. Some, including Isaac Asimov, have hypothesised that Greene was the co-author of Shakespeare's early plays, and was dissatisfied with the finished products overseen by the younger man. Around 1610, Shakespeare adapted the long-dead Greene's novel Pandosto: The Triumph of Time for the stage as The Winter's Tale.
