Sir Alan Patrick Herbert, CH (usually writing as A. P. Herbert or A. P. H.) (24 September 1890 – 11 November 1971) was an English humorist, novelist, playwright and law reform activist. He was an independent Member of Parliament (MP) for Oxford University for 15 years, five of which he combined with service in the Royal Navy.
He was born in Ashtead, Surrey, to Patrick Herbert, a civil servant, and Beatrice Herbert, née Selwyn. His mother died when he was seven years old. He had two younger brothers; both were killed in battle—one in 1914 and the other in 1941.
He was educated at Winchester College and New College, Oxford, obtaining a first class honours degree in jurisprudence. He was called to the bar by the Inner Temple in 1919, but never practised.
