Bertolt Brecht (1898-1956) is acknowledged as one of the great dramatists whose plays, work with the Berliner Ensemble and critical writings have had a considerable influence on the theatre. His landmark plays include The Threepenny Opera, Fear and Misery of the Third Reich, The Life of Galileo, Mother Courage and Her Children and The Caucasian Chalk Circle.

Jean Benedetti was born in 1930 and educated in England and France. He trained as an actor and teacher at the Rose Bruford College of Speech and Drama, returning in 1970 as Principal of the College until 1987. His published translations include Brecht's Edward II and A Respectable Wedding and Georges Michel's A Sunday Walk. From 1979 to 1987 he was chairman of the Theatre Education Committee of the International Theatre Institute (UNESCO).

John Willett (1917-2002) was the greatest English language authority on Brecht the writer and man of the theatre. The foremost translator and editor of Brecht's drama, poetry, letters, diaries, theatrical essays and fiction, Willett produced a dozen volumes for Methuen Drama on the greatest modern German writer.

Ralph Manheim (b. New York, 1907) was an American translator of German and French literature. His translating career began with a translation of Mein Kempf in which Manheim set out to reproduce Hitler's idiosyncratic, often grammatically aberrant style. In collaboration with John Willett, Manheim translated the works of Bertolt Brecht. The Pen/Ralph Manheim Medal for translation, inaugurated in his name, is a major lifetime achievement award in the field of translation. He himself won its predecessor, the PEN translation prize, in 1964. Manheim died in Cambridge in 1992. He was 85.
