Geoffrey Arundel Whitworth CBE (1883-1951) was an English lecturer and author who sought to promote amateur and professional theatre through the formation of the British Drama League, acting as its director for many years. Whitworth was instrumental in the founding of a National Theatre, and served the committee lobbying for this as its secretary. Though not an actor or playwright, he was praised by George Bernard Shaw as one of the most important figures in the history of British theatre. The library he assembled is a large and important collection, now held at the Theatre Museum at Convent Garden.[1]
