Mander and MitchensonRaymond Mander (15 July 1911 – 27 December 1988) and Joe Mitchenson (4 October 1911 – 7 October 1992) were theatre historians and joint founders of a large collection of theatrical memorabilia.
Both began their careers as actors, but what began as a shared hobby turned into full-time work in running the Mander and Mitchenson Theatre Collection (MMTC) and writing books, reviews and articles on theatre, opera and ballet. The collection remained their private property until 1977, when they handed it over to a trust. After the deaths of the founders the collection was moved first to the Jerwood Library of the Performing Arts in Greenwich, and, in 2010, to the Theatre Collection of the University of Bristol.
During the founders' lifetimes the collection contributed illustrations to more than four hundred books, and has remained one of the most important resources for authors writing about history of the British theatre. Provided by Wikipedia
