Who is this particular inventor from XIX century?

Question

I came acros with the following description about a certain inventor from XIX century:

An illustrious 19th-century European character who amassed an immense fortune thanks to his more than three hundred inventions, has passed to the annals of history for having developed a device with a photosynthetic organism that was a true economic reef for this inventor. After making a public demonstration of the benefits of this invention in British territory, the German authorities and the Scandinavian countries began to manufacture it, while the British, somewhat more reluctant, would authorize its production several years later. When its use was extended to the industry or public works, among others, the patent made the assets of this character increase substantially.

Additional background: It was also mentioned that this particular substance is related to the inventor:

Answer 1

I believe the correct answer is Alfred Nobel, as you already surmised.

.... Finally, [Nobel] tried diatomaceous earth, ..., that he brought from the Elbe River near his factory in Hamburg, which successfully stabilized the nitroglycerin into a portable explosive.

Nobel obtained patents for his inventions in England on 7 May 1867

The additional pictorial hint is diatomaceous earth, Nobel's stabilizer for nitroglycerin in inventing and manufacturing dynamite:

diatomaceous earth: ... a naturally occurring, soft, siliceous sedimentary rock that is easily crumbled into a fine white to off-white powder. ....

Diatomaceous earth consists of fossilized remains of diatoms, a type of hard-shelled protist. It is used as ..., a stabilizing component for dynamite, ....

As for diatoms:

Similar to plants, diatoms convert light energy to chemical energy by photosynthesis ....
