Context paragraphs:
Effie Bancroft: Marie Effie Wilton, Lady Bancroft (1839–1921) was an English actress and theatre manager.  She appeared onstage as Marie Wilton until after her marriage in December 1867 to Squire Bancroft, when she adopted his last name.  Bancroft and her husband were important in the development of Victorian era theatre through their presentation of innovative plays at the London theatres that they managed, first the Prince of Wales's Theatre and later the Haymarket Theatre.

William Greet: William Greet (1851 – 25 April 1914) was a British theatre manager from the end of the 19th century and into the 20th century.  Originally a business manager for other theatre licensees in the 1880s, he branched out as an independent manager in the 1890s and was associated with various London theatres, principally the Lyric, the Savoy and the Adelphi Theatres.

Globe Theatre (Newcastle Street): The Globe was a Victorian theatre built in 1868 and demolished in 1902.  It was the third of five London theatres to bear the name.  It was also known at various times as the Royal Globe Theatre or Globe Theatre Royal.  Its repertoire consisted mainly of comedies and musical shows.  The theatre's most famous production was "Charley's Aunt" by Brandon Thomas, which enjoyed a record-setting run at the theatre, having transferred to it from the Royalty Theatre.

The Swan (theatre): The Swan was a theatre in Southwark, London, England, built in 1595 on top of a previously standing structure, during the first half of William Shakespeare's career.  It was the fifth in the series of large public playhouses of London, after James Burbage's The Theatre (1576) and Curtain (1577), the Newington Butts Theatre (between 1575 and 1577) and Philip Henslowe's Rose (1587–88).

The Duke's Mistress: The Duke's Mistress is a Caroline era stage play, a tragicomedy written by James Shirley and first published in 1638.  It was the last of Shirley's plays produced before the major break in his career: with the closing of the London theatres due to bubonic plague in May 1636, Shirley left England for Ireland, where he worked under John Ogilby at the Werburgh Street Theatre in Dublin for four years.

Newington Butts Theatre: The Newington Butts Theatre was one of the earliest Elizabethan theatres, possibly predating even The Theatre of 1576 and the Curtain Theatre, which are usually regarded as the first dedicated playhouses in London.  William Ingram believes it was probably the first of the three to begin construction, and may have been the first completed.

Delfont Mackintosh Theatres: Delfont Mackintosh Theatres is a theatre group owned by British theatrical producer Sir Cameron Mackintosh.  The company was founded in 1991 by Mackintosh and Bernard Delfont.  The group owns eight London theatres.

Curtain Theatre: The Curtain Theatre was an Elizabethan playhouse located in Hewett Street, Shoreditch (part of the modern London Borough of Hackney), just outside the City of London.  It opened in 1577, and continued staging plays until 1624.

Hope Theatre: The Hope Theatre was one of the theatres built in and around London for the presentation of plays in English Renaissance theatre, comparable to the Globe, the Curtain, the Swan, and other famous theatres of the era.

Wyndham's Theatre: Wyndham's Theatre is a West End theatre, one of two opened by the actor/manager Charles Wyndham (the other is the Criterion Theatre).  Located on Charing Cross Road in the City of Westminster, it was designed c.1898 by W.G.R. Sprague, the architect of six other London theatres between then and 1916.  It was designed to seat 759 patrons on three levels although later refurbishment increased this to four.  The theatre was Grade II* listed by English Heritage in September 1960.
