Betterton, Thomas (?1635–1710), English actor, the greatest figure of the Restoration stage. He was in the company which reopened the
Cockpit in 1660, and soon after joined
Davenant's company at
Lincoln's Inn Fields Theatre. After Davenant's death in 1671, the company, of which Betterton was by then joint manager with Henry
Harris, moved to a new theatre in
Dorset Garden, and remained there until it was amalgamated with the company at the Theatre Royal in 1682. In 1695 Betterton broke with the management of the Theatre Royal and successfully reopened the theatre in Lincoln's Inn Fields with the first performance of
Congreve's Love for Love, moving 10 years later to
Vanbrugh's new theatre in the Haymarket (see
HER MAJESTY'S THEATRE). He was a good manager and an excellent actor, both in comedy and tragedy, his Hamlet and Sir Toby Belch (in
Twelfth Night) being equally admired. He adapted a number of Shakespeare's plays to suit the taste of the time, and in 1690 turned
Fletcher's The Prophetess (1622) into an opera with music by Purcell. Though not so well suited to
Restoration comedy he excelled in
heroic drama, and created many leading roles by contemporary dramatists. Betterton's wife was
Mary Saunderson (?–1712), one of the first English actresses, whom
Pepys in his Diary always refers to as lanthe, from her excellent playing of that part in Davenant's
The Siege of Rhodes.
