Shrapnel

Origin

From Henry Shrapnel, British army officer who invented an anti-personnel shell that transported a large number of bullets to the target before releasing them, at a far greater distance than rifles could fire the bullets individually. The surname is likely a metathesised form of Charbonnel, a diminutive of Old French "charbon" (charcoal) in reference to hair colour, complexion, or the like.
