In 1931, he began to write London theatre reviews for The Christian Science Monitor. In 1935, he was employed on the paper's staff, remaining its London drama critic until 1974.[1] He was an assistant literary editor for The Sunday Times from 1944 and later became its drama critic (1947–76).
Hobson was the only drama critic to recognise the early Harold Pinter's talent as a dramatist[2] and wrote of The Birthday Party: "I am willing to risk whatever reputation I have as a judge of plays by saying ... that Mr Pinter, on the evidence of this work, possesses the most original, disturbing and arresting talent in theatrical London."[3] During his career, he was to champion many other new playwrights, especially John Osborne, Samuel Beckett and Tom Stoppard.
Hobson wrote books relating to British and French theatre, including his autobiography Indirect Journey (1978), and a personal history based on his work as a drama critic, Theatre in Britain (1984). He also wrote a novel, The Devil in Woodford Wells (1946).[4]
