Theodore Edward Hook was an English man of letters and composer and briefly a civil servant in Mauritius. He is best known for his practical jokes, particularly the Berners Street hoax in 1809. The world's first postcard was received by Hook in 1840; he likely posted it to himself.

The Berners Street hoax was perpetrated by Theodore Hook in Westminster, London, England, in 1810. Hook had made a bet with his friend Samuel Beazley that he could transform any house in London into the most talked-about address in a week, which he achieved by sending out thousands of letters in the name of Mrs Tottenham, who lived at 54 Berners Street, requesting deliveries, visitors and assistance.
