"Prince George, Duke of Cambridge KG KT KP GCB GCH GCSI GCMG GCIE GCVO VD PC (George William Frederick Charles; 26 March 1819 ? 17 March 1904) was a member of the British Royal Family, a male-line grandson of King George III and maternal uncle of Queen Mary, consort of King George V. The Duke was an army officer by profession and served as Commander-in-Chief of the Forces (military head of the British Army) from 1856 to 1895. He became Duke of Cambridge in 1850 and Field Marshal in 1862."--Wikipedia.

Son of the eccentric Adolphus, seventh and favourite son of George III, Prince George was born in 1819 and was briefly heir presumptive to the throne of England until the birth that same year of his cousin Victoria. Instead he became George, second Duke of Cambridge, and rose to be Commander-in-Chief of the Army aged 37, holding that position for 39 years. Often considered a hidebound reactionary, he nonetheless took a keen interest in reform of the Army, and made considerable efforts to improve the soldier's lot. In the year that the title of Duke and Duchess of Cambridge was bestowed by HRH the Queen upon Prince William and Catherine Middleton on the morning of their wedding, this charming, substantial and formidably researched life of 'The Royal George' has a renewed topicality.
