Captain Frederick Marryat (10 July 1792 - 9 August 1848) was a British Royal Navy officer, a novelist, and an acquaintance of Charles Dickens. He is noted today as an early pioneer of the sea story, particularly for his semi-autobiographical novel Mr Midshipman Easy (1836), for his children's novel The Children of the New Forest (1847), and for a widely used system of maritime flag signalling, known as Marryat's Code.
