Arthur Lyulph Stanley, 5th Baron Stanley of Alderley, (14 September 1875 – 22 August 1931), also 5th Baron Sheffield and 4th Baron Eddisbury, was an English nobleman and Governor of Victoria from 1914 to 1920.
Stanley was the second child and first son of Edward Lyulph Stanley, 4th Baron Stanley and Mary Katherine Bell. On 29 August 1905 he married Margaret Evelyn Evans Gordon. They had five children:
Stanley was educated at Eton College and Balliol College, University of Oxford, where obtained a Bachelor of Arts in 1898. In 1902 he was called to the bar at the Inner Temple. In 1904 he became a London County Councillor and in 1906 became Liberal Member of Parliament for Eddisbury in Cheshire near the family seat. Whilst an MP he was Parliamentary Secretary to the Postmaster General serving under Sydney Buxton. His sister, Venetia Stanley, was a close correspondent of the Prime Minister and leader of the Liberal party, H. H. Asquith.
Stanley had been commissioned an officer in the Royal Anglesey Engineers Militia in May 1900, and saw active service in South Africa during the Second Boer War. He was promoted to captain on 6 December 1902.
In 1913 he was serving as High Sheriff of Anglesey when he was appointed Governor of Victoria. He was made a Knight Commander of the Order of St Michael and St George and took up his post on 23 February 1914. He served a five-year term and an additional year until relinquishing the post on 30 January 1920, although he had returned to Britain the previous year due to ill health. In the 1923 General election he stood unsuccessfully as Liberal candidate for Knutsford, losing by 80 votes to Conservative, Sir Ernest Makins. From 1925 to 1928 he was Chairman of the Royal Colonial Institute and of the East Africa Joint Committee.
In 1925 he succeeded his father to the three baronies and was known by the Stanley title. He died in August 1931 of a bacterial infection, actinomycosis. He was succeeded by his son Edward.
In his capacity as former Governor of Victoria, he attended the Covent Garden farewell of the Australian soprano Nellie Melba, and made a speech thanking her for her artistry and war-work. HMV recorded several excerpts of the evening, including Lord Stanley's speech, all of which can be heard on CD today.[3] [4]
