Major Lord Henry Arthur George Somerset, DL (17 November 1851 – 26 May 1926) was the third son of the 8th Duke of Beaufort and his wife, the former Lady Georgiana Curzon.

[4] In 1885 he was appointed to succeed Nigel Kingscote as superintendent of the stables and an extra equerry-in-waiting to the Prince of Wales (later King Edward VII).

[5] Lord Arthur Somerset was linked with the Cleveland Street scandal, in which he was identified and named by several male prostitutes as a customer of their services.

It is believed that he gave the police the initials of a member of the royal family "P. A. V.", which stood for Prince Albert Victor, the second in line to the throne, who – he alleged – also frequented the brothel.

[9] From there he travelled through Constantinople, Budapest, Vienna, and back to France, where he settled, living with an Englishman, James Neale,[10] until his death in 1926, aged 74.
