Alfred Nobel's actions as both a scientist and an industrialist led to his lasting legacy: the establishment of the highly esteemed Nobel Prizes.  His experiments to stabilize nitroglycerin led to the creation of dynamite which contributed to his massive wealth, and became instrumental in building roads, tunnels, and canals around the world.  Although his primary intention was peaceful use, Nobel realized that ultimately dynamite would be used as a weapon of war.  Unable to accept this as his legacy, Nobel rewrote his will to include a vast sum of money to establish a prize foundation to honor those who "have conferred the greatest benefit to mankind" (Nobel).
