Kenneth Augustus Muir Mackenzie, 1st Baron Muir Mackenzie GCB PC QC (29 June 1845 – 22 May 1930), was a British barrister, civil servant and Labour politician.

Background and education[edit]

Muir Mackenzie was a younger son of Sir John Muir Mackenzie, 2nd Baronet, and Sophia Matilda, daughter of James Raymond Johnstone, of Alva, Clackmannanshire. He was educated at Charterhouse School and Balliol College, Oxford. In 1873 he was called to the Bar, Lincoln's Inn.[1]


Muir Mackenzie was Clerk to the Crown in Treasury from 1885 to 1915 and served as Permanent Secretary to the Lord Chancellor from 1890 to 1915. He was appointed a Queen's Counsel in 1887 and a Bencher of Lincoln's Inn in 1891. He was made a CB in 1893,[2] a KCB in 1898[3] and a GCB in 1911[1][4] and in 1915 he was raised to the peerage as Baron Muir Mackenzie, of Delvine in the County of Perth.[5] In February 1924 Muir Mackenzie, then aged 78, was appointed a Lord-in-Waiting (government whip in the House of Lords) by Prime Minister Ramsay Macdonald, head of the first ever Labour government,[1] and was sworn of the Privy Council the same year.[6] He held this position until the government fell in November 1924 and again from 1929 to 1930.[1] At the time of his death he was the oldest government minister of the twentieth century.


Lord Muir-Mackenzie married Amelia, daughter of William Graham, MP, in 1874. They had one son and three daughters. His wife died in 1900 and his only son William in 1901, aged 25 and unmarried. Muir-Mackenzie died at his home in Cumberland Terrace, Regent's Park, London, in May 1930, aged 84, and was cremated at Golders Green Crematorium.[7] As he had no surviving male issue the barony became extinct on his death.[1]
