I developed nitroglycerin so roads could be blasted out of mountains instead of human labor. I manufactured nitroglycerin but my factory blew up. Through further experimenting, I invented dynamite. I was a bachelor and I eventually became wealthy enough to leave nine million dollars for Prizes to be awarded each year for high achievement. These awards and an Institute in Sweden are named after me. U. S. President Obama received one of my awards this year.
Who am I?
