Surgeon General William George Nicholas Manley, was a British Army officer, surgeon and a recipient of the Victoria Cross, the highest award for gallantry in the face of the enemy that can be awarded to British and Commonwealth forces. He received awards from several other countries, and is the only person to have been awarded both the VC and the Iron Cross.

The Victoria Cross (VC) is the highest and most prestigious decoration of the British honours system. It is awarded for valour "in the presence of the enemy" to members of the British Armed Forces and may be awarded posthumously. It was previously awarded by countries of the Commonwealth of Nations, most of which have established their own honours systems and no longer recommend British honours. It may be awarded to a person of any military rank in any service and to civilians under military command. No civilian has received the award since 1879. Since the first awards were presented by Queen Victoria in 1857, two thirds of all awards have been personally presented by the British monarch. The investitures are usually held at Buckingham Palace.
