Douglas William Jerrold (London 3 January 1803 – 8 June 1857 London) was an English dramatist and writer.
Jerrold's father, Samuel Jerrold, was an actor and lessee of the little theatre of Wilsby near Cranbrook in Kent. In 1807 Douglas moved to Sheerness, where he spent his childhood. He occasionally took a child part on the stage, but his father's profession held little attraction for him. In December 1813 he joined the guardship Namur, where he had Jane Austen's brother Francis as captain, and served as a midshipman until the peace of 1815. He saw nothing of the war save a number of wounded soldiers from Waterloo, but he retained an affection for the sea.
The peace of 1815 ruined Jerrold's father; on 1 January 1816 he took his family to London, where Douglas began work as a printer's apprentice, and in 1819 he became a compositor in the printing-office of the Sunday Monitor. Several short papers and copies of verses by him had already appeared in the sixpenny magazines, and a criticism of the opera Der Freischütz was admired by the editor, who requested further contributions. Thus Jerrold became a professional journalist.
Jerrold's figure was small and spare, and in later years bowed almost to deformity. His features were strongly marked and expressive, from the thin humorous lips to the keen blue eyes, gleaming from beneath the shaggy eyebrows. He was brisk and active, with the careless bluffness of a sailor. Open and sincere, he concealed neither his anger nor his pleasure; to his sailor's frankness all polite duplicity was distasteful. The cynical side of his nature he kept for his writings; in private life his hand was always open. In politics Jerrold was a Liberal, and he gave eager sympathy to Lajos Kossuth, Giuseppe Mazzini and Louis Blanc. In social politics especially he took an eager part; he never tired of declaiming against the horrors of war, the luxury of bishops, or the iniquity of capital punishment.
