King's Men personnel were the people who worked with and for the Lord Chamberlain's Men and the King's Men (for all practical purposes a single continuous theatrical enterprise) from 1594 to 1642 (and after). The company was the major theatrical enterprise of its era and featured some of the leading actors of their generation – Richard Burbage, John Lowin, and Joseph Taylor among other – and some leading clowns and comedians, like Will Kempe and Robert Armin. The company benefitted from the services of William Shakespeare, John Fletcher, and Philip Massinger as regular dramatists.
The actors who performed the plays have left the most evidence of their lives and activities; but they were supported by musicians and other functionaries, and were enabled by managers and financial backers like Cuthbert Burbage.
