Captain Frederick Marryat (10 July 1792 – 9 August 1848) was an English Royal Navy officer, novelist, and a contemporary and acquaintance of Charles Dickens, noted today as an early pioneer of the sea story. He is now known particularly for the semi-autobiographical novel Mr Midshipman Easy and his children's novel The Children of the New Forest, and for a widely used system of maritime flag signalling, known as Marryat's Code.
