At the end of the year 2018, the International Theatre Institute (ITI) bid farewell to Thilo Wittenbecher from his active work in the office. As director of the Mime Centrum Berlin - today part of the ITI - he has built up a place of work, information and documentation for the performing arts with international appeal since the early 1990s. Since 2011 it has been possible to transfer this institution into the programme of the ITI as a permanent project. Thilo Wittenbecher continues to be associated with the work of the Media Library and the International Theatre Institute through his professional involvement in individual projects.

His successor ist Christine Henniger, who has been working with the ITI since 2014. The studied linguist and philosopher will be in charge of the projects in the Mediathek - concerning digitisation and information services - as well as in Studio 2 concerning courses, workshops and rehearsals for international artists.
