Alfred Nobel: Life and Career

Born in Stockholm, Alfred Nobel was the fourth son of Immanuel Nobel (1801–1872), an inventor and engineer, and Andriette Ahlsell Nobel (1805–1889). The couple married in 1827 and had eight children. The family was impoverished, and only Alfred and his three brothers survived past childhood. Through his father, Alfred Nobel was a descendant of the Swedish scientist Olaus Rudbeck (1630–1702),and in his turn the boy was interested in engineering, particularly explosives, learning the basic principles from his father at a young age.
Following various business failures, Nobel's father moved to Saint Petersburg in 1837 and grew successful there as a manufacturer of machine tools and explosives. He invented modern plywood and started work on the "torpedo".In 1842, the family joined him in the city. Now prosperous, his parents were able to send Nobel to private tutors and the boy excelled in his studies, particularly in chemistry and languages, achieving fluency in English, French, German, and Russian. For 18 months, during 1841–1842, Nobel went to the only school he ever attended as a child, the Jacobs Apologistic School in Stockholm.

As a young man, Nobel studied with chemist Nikolai Zinin; then, in 1850, went to Paris to further the work; and, at 18, he went to the United States for four years to study chemistry, collaborating for a short period under inventor John Ericsson, who designed the American Civil War ironclad USS Monitor. Nobel filed his first patent, for a gas meter, in 1857.[2][5][1]
The family factory produced armaments for the Crimean War (1853–1856); but, had difficulty switching back to regular domestic production when the fighting ended and they filed for bankruptcy. In 1859, Nobel's father left his factory in the care of the second son, Ludvig Nobel (1831–1888), who greatly improved the business. Nobel and his parents returned to Sweden from Russia and Nobel devoted himself to the study of explosives, and especially to the safe manufacture and use of nitroglycerine (discovered in 1847 by Ascanio Sobrero, one of his fellow students under Théophile-Jules Pelouze at the University of Turin). Nobel invented a detonator in 1863; and, in 1865, he designed the blasting cap.
On 3 September 1864, a shed, used for the preparation of nitroglycerin, exploded at the factory in Heleneborg Stockholm, killing five people, including Nobel's younger brother Emil. Dogged by more minor accidents but unfazed, Nobel went on to build further factories, focusing on improving the stability of the explosives he was developing. Nobel invented dynamite in 1867, a substance easier and safer to handle than the more unstable nitroglycerin. Dynamite was patented in the US and the UK and was used extensively in mining and the building of transport networks internationally. In 1875 Nobel invented gelignite, more stable and powerful than dynamite, and in 1887 patented ballistite, a forerunner of cordite.
Nobel was elected a member of the Royal Swedish Academy of Sciences in 1884, the same institution that would later select laureates for two of the Nobel prizes, and he received an honorary doctorate from Uppsala University in 1893.
Nobel's brothers Ludvig and Robert exploited oilfields along the Caspian Sea and became hugely rich in their own right. Nobel invested in these and amassed great wealth through the development of these new oil regions. During his life Nobel issued 350 patents internationally and by his death had established 90 armaments factories, despite his belief in pacifism.
In 1891, following the death of his mother and his brother Ludvig and the end of a long standing relationship, Nobel moved from Paris to San Remo, Italy. Suffering from angina, Nobel died at home, of a cerebral haemorrhage in 1896. Unbeknownst to his family, friends or colleagues, he had left most of his wealth in trust, in order to fund the awards that would become known as the Nobel Prizes. He is buried in Norra begravningsplatsen in Stockholm.

Alfred Nobel:Father of Explosives

Alfred Bernhard Nobel ([äl'fred bern'härd nōbel'] About this sound listen) (21 October 1833 – 10 December 1896) was a Swedish chemist, engineer, innovator, and armaments manufacturer. He was the inventor of dynamite. Nobel also owned Bofors, which he had redirected from its previous role as primarily an iron and steel producer to a major manufacturer of cannon and other armaments. Nobel held 350 different patents, dynamite being the most famous. He used his fortune to posthumously institute the Nobel Prizes. The synthetic element nobelium was named after him. His name also survives in modern-day companies such as Dynamite Nobel and Akzo Nobel, which are descendants of the companies Nobel himself established.

Department of Transportation (DOT) changes


a. In 1991 the DOT adopted into federal law a different system
for hazard classification of dangerous goods. The new system is
essentially that which is used by United Nations for the transportation
of dangerous goods. The total phase-in period for the new
system is ten years. The 49 CFR (App A, Ref 3) has more detailed
information regarding the different phase-in periods for specific
situations and should be consulted as the authoritative source. The
JHCS will continue to have the old DOT information for the entire
phase-in period of ten years.
b. For new items added to the JHCS after April 1991, there will
be no DOT (old system) information added.
c. For those items added after April 1991, the DOT hazard class
for Class 1 items will be the DoD Hazard Division Compatibility
Group. Any parenthetical values appearing in the DoD hazard class
will not be included in the DOT hazard class. For those items where
the DoD Hazard Division Compatibility Group is other than Class 1
 (i.e., Class 2–9), the DOT class will consist only of the DoD Hazard
Division. No Compatibility Group for Class 2–9 will be included in
the DOT hazard class; whereas, it will be for DoD.
d. For those items entered in the JHCS after April 1991, the DOT
label for Class 1 items will be the word “Explosive” followed by the
DOT hazard class (i.e., 1.2C). For Class 2–9 consult 49 CFR (App
A, Ref 3).
e. For those items entered after April 1991, the DOT container
marking for Class 1 items will consist of the Proper Shipping Name
(as defined by the UN Serial Number), the UN Serial Number, and
the NSN or part number. The NSN or part number may be used
only if it is directly traceable to a DOT assigned registration number
(i.e., “EX” number). All of these data elements are in the JHCS.
