artillery officer and inventor of a form of artillery case shot. Commissioned in the Royal Artillery in 1779, he served in Newfoundland, Gibraltar, and the West Indies and was wounded in Flanders in the Duke of York's unsuccessful campaign against the French in 1793. In 1804 he became an inspector of artillery and spent several years at Woolwich arsenal.

Shrapnel's invention, perfected by long, private research, consisted of a spherical projectile filled with bullets and fitted with a small charge fired by a time fuse; as the projectile neared the enemy lines, the charge burst the container, and the bullets continued onward in a widening swath. Later versions altered the spherical projectile to a cylindrical shape and increased the bursting charge. The introduction of high-explosive ammunition led to the abandonment of case shot, the violently exploded shell casing itself serving the purpose far better. The term shrapnel continued to be used to designate such shell splinters.
