Alfred Nobel was born in Stockholm on October 21, 1833. His father 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,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 who, three years earlier, had invented , 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, remained in St. Petersburg. With some difficulties they managed to salvage the family enterprise and then went on to develop the 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 . 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.

Intensive work and travel did not leave much time for a private life. At the age of 43 he was 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 51491lhu24pmd8k

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 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 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,This was not without its difficulties since the will was contested by relatives and questioned by authorities in various countries.
