Alfred Nobel was born in Stockholm on October 21, 1833. His father
HYPERLINK "immanuel.html" Immanuel Nobel was an engineer and inventor
who built bridges and buildings in Stockholm. In connection with his
construction work Immanuel Nobel also experimented with different
techniques of blasting rock.

Alfred s mother, HYPERLINK "andrietta.html" Andrietta Ahlsell came
from a wealthy family. Due to misfortunes in the construction work
caused by the loss of some barges of building material, Immanuel Nobel
was forced into bankruptcy the same year Alfred Nobel was born. In 1837
Immanuel Nobel left Stockholm and his family to start a new career in
Finland and in Russia. To support the family, Andrietta Nobel started a
grocery store which provided a modest income. Meanwhile Immanuel Nobel
was successful in his new enterprise in St. Petersburg, Russia. He
started a mechanical workshop which provided equipment for the Russian
army and he also convinced the Tsar and his generals that naval mines
could be used to block enemy naval ships from threatening the city.

The naval mines designed by Immanuel Nobel were simple devices
consisting of submerged wooden casks filled with gun powder. Anchored
below the surface of the Gulf of Finland they effectively deterred the
British Royal Navy from moving into firing range of St. Petersburg
during the Crimean war (1853-1856). Immanuel Nobel was also a pioneer in
arms manufacture and in designing steam engines. Successful in his
industrial and business ventures, Immanuel Nobel was able, in 1842, to
bring his family to St. Petersburg. There, his sons were given a first
class education by private teachers. The training included natural
sciences, languages and literature. By the age of 17 Alfred Nobel was
fluent in Swedish, Russian, French, English and German. His primary
interests were in English literature and poetry as well as in chemistry
and physics. Alfred s father, who wanted his sons to join his enterprise
as engineers, disliked Alfred s interest in poetry and found his son
rather introverted. In order to widen Alfred s horizons his father sent
him abroad for further training in chemical engineering. During a two
year period Alfred Nobel visited Sweden, Germany, France and the United
States. In Paris, the city he came to like best, he worked in the
private laboratory of Professor T.J. Pelouze, a famous chemist. There he
met the young Italian chemist HYPERLINK "sobrero.html" Ascanio Sobrero
who, three years earlier, had invented HYPERLINK "nitrodyn.html"
nitroglycerine , a highly explosive liquid. Nitroglycerine was produced
by mixing glycerine with sulphuric and nitric acid. It was considered
too dangerous to be of any practical use. Although its explosive power
greatly exceeded that of gun powder, the liquid would explode in a very
unpredictable manner if subjected to heat and pressure. Alfred Nobel
became very interested in nitroglycerine and how it could be put to
practical use in construction work. He also realized that the safety
problems had to be solved and a method had to be developed for the
controlled detonation of nitroglycerine. In the United States he visited
John Ericsson, the Swedish-American engineer who had developed the screw
propeller for ships. In 1852 Alfred Nobel was asked to come back and
work in the family enterprise which was booming because of its
deliveries to the Russian army. Together with his father he performed
experiments to develop nitroglycerine as a commercially and technically
useful explosive. As the war ended and conditions changed, Immanuel
Nobel was again forced into bankruptcy. Immanuel and two of his sons,
Alfred and Emil, left St. Petersburg together and returned to Stockholm.
His other two sons, HYPERLINK "russia.html" Robert and Ludvig ,
remained in St. Petersburg. With some difficulties they managed to
salvage the family enterprise and then went on to develop the HYPERLINK
"russia.html" oil industry in the southern part of the Russian empire.
They were very successful and became some of the wealthiest persons of
their time.
After his return to Sweden in 1863, Alfred Nobel concentrated on
developing nitroglycerine as an explosive. Several explosions, including
one (1864) in which his brother Emil and several other
persons were killed, convinced the authorities that nitroglycerine
production was exceedingly dangerous. They forbade further
experimentation with nitroglycerine within the Stockholm city limits and
Alfred Nobel had to move his experimentation to a barge anchored on Lake
Mälaren. Alfred was not discouraged and in 1864 he was able to start
mass production of nitroglycerine. To make the handling of
nitroglycerine safer Alfred Nobel experimented with different additives.
He soon found that mixing nitroglycerine with silica would turn the
liquid into a paste which could be shaped into rods of a size and form
suitable for insertion into drilling holes. In 1867 he patented this
material under the name of HYPERLINK "nitrodyn.html" dynamite . To be
able to detonate the dynamite rods he also invented a detonator
(blasting cap) which could be ignited by lighting a fuse. These
inventions were made at the same time as the diamond drilling crown and
the pneumatic drill came into general use. Together these inventions
drastically reduced the cost of blasting rock, drilling tunnels,
building canals and many other forms of construction work.

The market for dynamite and detonating caps grew very rapidly and Alfred
Nobel also proved himself to be a very skilful entrepreneur and business
man. By 1865 his factory in Krümmel near Hamburg, Germany, was
exporting nitroglycerine explosives to other countries in, Europe
America and Australia. Over the years he founded factories and
laboratories in some 90 differe nt places in more than 20 countries.
Although he lived in Paris much of his life he was constantly
travelling. Victor Hugo at one time described him as "Europe s richest
vagabond". When he was not travelling or engaging in business activities
Nobel himself worked intensively in his various laboratories, first in
Stockholm and later in Hamburg (Germany), Ardeer (Scotland), Paris
(France), Karlskoga (Sweden) and San Remo (Italy). He focused on the
development of explosives technology as well as other chemical
inventions, including such materials as synthetic rubber and leather,
artificial silk etc. By the time of his death in 1896 he had 355
patents.
feeling like an old man. At this time he advertised in a newspaper
"Wealthy, highly educated elderly gentleman seeks lady of mature age,
versed in languages, as secretary and supervisor of
household". The most qualified applicant turned out to be an Austrian
woman, Countess Bertha Kinsky. After working for Nobel for about two
months she decided to return to Austria to marry Count Arthur von
Suttner. In spite of this Alfred Nobel and HYPERLINK "suttner.html"
Bertha von Suttner remained friends and kept writing letters to each
other for decades. Over the years Bertha von Suttner became increasingly
critical of the arms race. She wrote a famous book Lay Down Arms and
became a prominent figure in the peace movement. No doubt this
influenced Alfred Nobel when he wrote his final will which was to
include a Prize for persons or organizations who promoted peace. Several
years after the death of Alfred Nobel, the Norwegian Storting
(Parliament) decided to award the 1905 Nobel Peace Prize to Bertha von
Suttner.
Alfred Nobel s greatness lay in his ability to combine the penetrating
mind of the scientist and inventor with the forward-looking dynamism of
the industrialist. Nobel was very interested in social and peace-related
issues and held what were considered radical views in his era. He had a
great interest in literature and wrote his own poetry and dramatic
works. The Nobel Prizes became an extension and a fulfillment of his
lifetime interests.
Many of the companies founded by Nobel have developed into industrial
enterprises that still play a prominent role in the world economy, for
example Imperial Chemical Industries (ICI), Great Britain, Société
Centrale de Dynamite, France, and Dyno Industries in Norway. Toward the
end of his life, he acquired the company AB Bofors in Karlskoga, where
Björkborn Manor became his Swedish home. Alfred Nobel died in San Remo,
Italy, on December 10, 1896. When his HYPERLINK "will.html" will was
opened it came as a surprise that his fortune was to be used for Prizes
in Physics, Chemistry, Physiology or Medicine, Literature and Peace. The
executors of his will were two young engineers, HYPERLINK
"sohlman.html" Ragnar Sohlman and Rudolf Lilljequist. They set about
forming the HYPERLINK "../foundation/index.html" Nobel Foundation as
an organization to take care of the financial assets left by Nobel for
this purpose and to coordinate the work of the HYPERLINK
"../awarding/index.html" Prize-Awarding Institutions . This was not
without its difficulties since the will was contested by relatives and
questioned by authorities in various countries.
