Alfred Nobel was a Swedish chemist who lived from 1833 to 1896. Alfred and his brother made explosives, but in 1864 there was an accident in the laboratory and Alfred’s brother was killed. Alfred then decided to spend his life truing to make explosives safer to use.
One of the strongest explosives at that time was nitroglycerine. This explosive, which looks like oily water, is very dangerous to use or even to carry. Nobel wanted to study nitroglycerine so he could find a way to make it safer. Nobel had an idea of taking nitroglycerine out on a boat in the middle of a lake and working with it there.
When Nobel wanted to take the nitroglycerine he was working with from one place to another, he put it into small boxes. Then he put the small boxes into a larger box made of clay. One day, when he opened the large clay box, he found that nitroglycerine was coming out of one of the small boxes. To his surprise, the large clay box was still dry. This gave him the idea of mixing clay with nitroglycerine. The clay would take the oil out of nitroglycerine and make it safer. He called this explosive ‘dynamite’.
