The double-edged sword of discovery is exemplified by the life of Swedish chemist and inventor Alfred Nobel, who left instructions in his will to recognize people whose work was of the greatest benefit to mankind.
Nobel made a fortune by inventing dynamite, which greatly improved the safety of explosives. He initially hoped that his invention would put an end to war, by making it so horrible that no one would want to engage in it. Was wrong-He fundamentally wrong -but the wealth generated from his invention did create the Nobel Peace Prize.
A meeting with Italian chemist Ascanio Sobrero, inventor of nitroglycerine, led to Nobel's invention of dynamite. Because nitroglycerine and its production were difficult to control-an explosion killed Nobel's brother Emil in 1864 - Nobel tried adding different substances to make it safer. He eventually mixed it with silica, making a paste that could be shaped into rods and inserted into drilling holes. In 1867, he patented this material, calling it dynamite.
His invention was a boon 'during the era of rapidly growing industries and cities, because dynamite reduced the cost of blasting rock and drilling tunnels. It was a profitable one, too, and Nobel became a very wealthy man. In fact, Nobel held the patent for some 600 inventions, including dynamite.
