He was an English military officer that lived in the time of Napoleon:
In 1784, while a lieutenant in the Royal Artillery, he perfected, with his own resources, an invention of what he called “spherical case” ammunition: a hollow cannonball filled with lead shot that burst in mid-air. He successfully demonstrated this in 1787 at Gibraltar.[n 1] He intended the device as an anti-personnel weapon. In 1803, the British Army adopted a similar but elongated explosive shell which immediately acquired the inventor’s name. It has lent the term shrapnel to fragmentation from artillery shells and fragmentation in general ever since, long after it was replaced by high explosive rounds. Until the end of World War I, the shells were still manufactured according to his original principles.
