Yes he did. But he did so because of death. He found a way to stablize Nitro Glycerine (sp?) which produced TNT known as dynomite. He was horrified that his product would be used to kill. So upon his death, his amassed fortune was to be used to fund prizes in excellence in various academic subjects and the famous Peace Prize.
At least Nobel felt guilt, Tookie does not.
I didn't know his invention was sparked (HA!) by many people blowing themselves up with unstable nitro. That makes a lot more sense. Thanks for the background.
