Although Alfred Nobel officially settled in Sanremo in 1891, this does not mean that during his later years from 1891 to 1896, he had settled down.

fame, or just while away the hours in a sunny Mediterranean retreat.

This is not his character.

It can be seen from the many letters he sent there that the endless travel required by his work could not calm him down even now.

He visited several European capitals and many places where his factories and companies were located.

Paris accounted for half of his visits and was where he stayed the longest.

Despite persecution by the French government and press, he still had many connections with the capital.

He avoided getting involved in political and business disputes as much as possible, but if he did get involved in these disputes, he was fearless and was quick to fight them with his mouth and pen.

If he thought something was going wrong that threatened to interfere with his research, he had a knack for evading it.

He used old roll-up notebooks and letterheads, a fountain pen he designed himself, which must have been a unique new gadget at the time, and a special suitcase, all of which accompanied him on his travels.

And it shows that he has to work hard even in trains, ships and hotel rooms.

The interlude of political propaganda played by the French government and the dynamite control authorities in the mid-1890s over the far-from-smokeless explosives has died down.

The days of the Barb and Panama scandals are over, as is the vexing string of smokeless explosives lawsuits.

The inventor's vast business affairs were developing favorably and bringing in large incomes.

New general managers and independent companies and cartels have taken much of the heavy lifting off his shoulders, especially now that he has resigned from all board positions.

This 60-year-old man with Sanremo as his base camp has been exhausted by the experiences in his life.

However, even though he felt tired, he still felt that there was still a lot of things waiting for him to accomplish.

Those interesting problems that urgently need to be solved give him the strength to persist in his work.

He once said at this time: "I work intermittently. Sometimes I feel lonely, and then I work again. I often work like that, but for those things that I feel will be successful in the end. I will always seize

Don’t let go.” This is typical Nobel.

The inventor's trusted figure, Georges Fehrenbach, was regarded as a theoretically proficient chemist during the prolific Parisian years and was unwilling to leave his hometown.

Therefore, Nobel allowed him to receive his pension and leave his job; he also hired the British Hugh Beckett as the new chief chemist of the laboratory; his laboratory, built in the large garden of the Villa Sanremo, is

Equipped with the latest German equipment.

In 1893, he also hired the twenty-three-year-old Swedish explosives chemist Ragnar Solman (1870-1948), who had just returned from a technical job in the United States.

Practice has proved that this is a very important step.

Solman, a genius, humble and honest man, not only became, as Nobel himself said: "one of my few favorites" but also became the main executor of his will.

He was one of those who deserved the credit for carrying out this extraordinary testament which benefited the world.

With tireless efforts, often in spectacular circumstances, he overcame the many difficulties encountered in establishing the Nobel Foundation and in receiving the funds for the award contained in this will.

with obstacles.

He also devoted his life to Nobel's many aspects of his legacy.

Nobel built a small pier jutting out into the sea at Sanremo to conduct explosives and firearms experiments; he worked there for five years in a highly intense manner.

The basic work of several important inventions that Nobel did not complete during his lifetime was done there; later, these inventions were successfully tested by others and played a role in promoting some major events.

Nobel's final discovery in the field of explosives, the so-called "improved smokeless explosive" (the first invention patent registered in Sweden is No. 7552 of 1896), is a hybrid smokeless explosive further developed to suit certain special purposes.

Smoke explosives were created in this laboratory.

If we want to thoroughly explain this invention, we need to involve the technical details of cannon and internal ballistics; so here we can only simply say that its purpose is to "increase the muzzle velocity of the projectile without increasing the maximum pressure inside the weapon."

; This is done by inducing a certain increased incremental force in the burning of the explosive, so that as the projectile advances within the gun chamber, the pressure is maintained and the overall ballistic action increases the consumption of explosive for this advance.

From two aspects: mechanically, through the progressive increase of the surface layer of the explosive pellets during the combustion process; and chemically, through the individual explosive pellets, which are made into various layers.

The various layers allowed the inner layer to burn at a greater rate, thereby increasing the effectiveness of the combustion process." Manufacturing and testing of improved explosives began in several Nobel factories, mainly in 1895.

Between 1896 and 1896, experiments were carried out in the inventor's new Swedish laboratory in Bjerkborn, near Bofors.
