Who invented shrapnel?

I'm curious, who was the genius behind the invention of shrapnel? Was it a military strategist looking to revolutionize warfare, or perhaps a scientist experimenting with explosives? I'm eager to learn about the mind that conceived of this devastating yet effective ammunition, and how their discovery came to be. Was it a chance occurrence, or the culmination of years of research and development? I'm intrigued to know the full story behind the invention of shrapnel, and who deserves the credit for this significant contribution to military technology.
