William Sidney, 1st Viscount De L'Isle

William Philip Sidney, 1st Viscount De L'Isle, was a British Army officer, politician, and Victoria Cross recipient who later served as the 15th governor-general of Australia from 1961 to 1965. Notably, he was the last non-Australian to hold the position and the last British national to be appointed Governor-General of any Commonwealth realm.

During his military service in the British Army, he attained the rank of Major. He was decorated with the Victoria Cross, the highest award for gallantry in the face of the enemy that can be awarded to British and Commonwealth forces.

In his later years, he was appointed a Knight Companion of the Order of the Garter, achieving the rare distinction of being one of only two men to hold both the Victoria Cross and the Order of the Garter. He also held several other prestigious appointments, including Knight Grand Cross of the Order of St Michael and St George and Knight Grand Cross of the Royal Victorian Order.
