Lieutenant-Commander John Bryan Peter Duppa-Miller, GC (born Miller;[1] 22 May 1903 – 15 December 1994) was a Royal Navy officer who was awarded the George Cross for his "great gallantry and undaunted devotion to duty" in bomb disposal work during the Blitz of late 1940.

[2] Temporary Sub-Lieutenant Miller, working closely with Able Seaman Stephen Tuckwell, defused and rendered safe numerous enemy bombs and mines.

They were both awarded the George Cross for dealing with a parachute mine that had fallen into the soft mud bank of the Roding River, which runs into Barking Creek.

The two experts got back into the water, put ropes round the mine, and with the assistance of the crane-drivers, the huge cylinder was dragged slowly out of the creek, over the muddy bank and up on to the wharf.

[4] The King has been graciously pleased to approve the award of the GEORGE CROSS for great gallantry and undaunted devotion to duty, to: — Probationary Temporary Sub-Lieutenant John Bryan Peter Miller, R.N.V.R.Miller married three times.
