Charles Philip Yorke, 5th Earl of Hardwicke, (23 April 1836 – 18 May 1897), styled Viscount Royston until 1873, was a British aristocrat, Conservative politician and dandy.[2]
Hardwicke was the eldest son of Admiral Charles Yorke, 4th Earl of Hardwicke, and the Hon. Susan, daughter of Thomas Liddell, 1st Baron Ravensworth. Elliot Yorke was his younger brother.[3]
While studying at Trinity College, Cambridge, Hardwicke played first-class cricket on four occasions for Cambridge University Cricket Club in 1856 and 1857.[4] He was also a Freemason, initiated into Lodge of Himalayan Brotherhood No. 459[5] and was appointed Provincial Grand Master of Cambridgeshire in 1872.[6]
Hardwicke was returned to Parliament for Cambridgeshire in 1865[3] [7] (succeeding his uncle Eliot Yorke) and served under the Earl of Derby and Benjamin Disraeli as Comptroller of the Household between 1866 and 1868.[3] He was sworn of the Privy Council in 1866.
In 1873 he succeeded his father in the earldom and to his estates, including Wimpole Hall in Cambridgeshire, and entered the House of Lords.[3] The following year he was appointed Master of the Buckhounds under Disraeli, and continued in this post until the government fell in 1880.
In 1879 Lord Hardwicke had a horse race, the Hardwicke Stakes, named after him.[8] [9]
An inveterate gambler, the 5th Earl racked up huge debts with the Agar-Robartes Bank and was obliged to put the Wimpole Hall Estate up for sale by auction in 1891. When it failed to raise the reserve price Lord Robartes, as Chairman of Agar-Robartes Bank, accepted the estate in settlement.
Lord Hardwicke married Lady Sophia Georgiana Robertina, daughter of Henry Wellesley, 1st Earl Cowley, in 1863. They had one son and two daughters.
He died in May 1897, aged 61, and was succeeded in the earldom by his only son, Albert. The Countess of Hardwicke died in June 1923.[3]
