Brigadier-General Frederick William Lumsden, was a British officer in Royal Marine Artillery and during the First World War. During his service he was decorated four times for valorous service and saw action in several major campaigns before he was killed just months before the war's end in June 1918. Amongst his decorations was the Victoria Cross, the highest award for gallantry to British or Commonwealth troops. He was also the first of seven British officers to be awarded the DSO four times in the First World War.

The Distinguished Service Order (DSO) is a military decoration of the United Kingdom, as well as formerly of other parts of the Commonwealth, awarded for operational gallantry for highly successful command and leadership during active operations, typically in actual combat. Since 1993 it has been awarded specifically for "highly successful command and leadership during active operations", with all ranks being eligible. It is a level 2A decoration (order) in the British system of military decorations.
