Sir Richard Birnie (c. 1760 – 1832) was a Scottish police magistrate in London, who came to prominence for his involvement with the Cato Street Conspiracy.
He was a native of Banff, Aberdeenshire, born about 1760. After serving an apprenticeship to a saddler he came to London, and worked for the house of Macintosh & Co., in the Haymarket, saddlers and harness-makers to the royal family. In favour with the Prince of Wales, he was made foreman and eventually a partner in the business; he married the daughter of a wealthy baker.[1]
After his marriage Birnie rented a house in St Martin-in-the-Fields parish, and took part in parochial affairs. He established almshouses in Pratt Street, Camden Town. He also enrolled himself in the Royal Westminster Volunteers, in which he became a captain. At the request of the Duke of Northumberland he was placed in the commission of the peace, and began to frequent the Bow Street Magistrates' Court.[1]
In time Birnie was appointed police magistrate at Union Hall court[1] (which later became Southwark Police Court).[2] After a few years he was promoted to be a magistrate at Bow Street. In February 1820 he headed the police officers in the apprehension of the Cato Street conspirators.[1]
At the funeral of Queen Caroline in August 1821 Birnie took the initiative in reading the Riot Act, which Sir Robert Baker, the chief magistrate, refused to do.[1] Shortly afterwards Baker resigned; he had been criticised, for example by the Tory Harriet Arbuthnot for his soft line, in the violent circumstances where there had already been deaths.[3] Birnie was appointed to succeed him, and a knighthood was conferred on him in the September following.[1]
In 1823, Birnie refused to enforce the unpopular Poor rate in Acton, causing it to be reduced for some householders.[4]
Birnie retained throughout life the special favour of George IV. He died on 29 April 1832.[1]
Birnie and his wife Louisa had a son Richard Birnie (1808–1888), a barrister and journalist, who emigrated to Australia in 1854.[5]
