In the 1860s Heleneborg was owned by W.N. Burmester, who housed the manufacturer and inventor Immanuel Nobel on the premises. There his son Alfred Nobel and Alfred's brothers experimented with the safe handling of the explosive nitroglycerin. After a big explosion in this plant on September 3, 1864, which killed the youngest brother, Emil Oskar Nobel, Alfred Nobel created the Alfred Nobel &amp; Company in Germany to continue his work in more isolated circumstances.
