When Alfred was 17 years old, he traveled to the United States and several European countries to study.
Alfred and his father experimented with nitroglycerin. Finally, in 1863, Alfred invented a way to make it more safe . Scientists everywhere praised his work. Nitroglycerin had many good uses.
The Nobels continued to experiment to make nitroglycerin safer. Unfortunately, in September 1864. Alfred's brother, Emil, was killed in an explosion in their laboratory. After the accident, Immanuel had a stroke and was paralyzed. He died eight years later, on the same day Emil had died.
Alfred Nobel wanted to make nitro-glycerin safe. He built a new laboratory and continued his work. In 1867, he discovered a new material to mix with the nitroglycerin. This material made the nitroglycerin safer and more effective. He called his new invention "dynamite“.
